TASK: Retrieve occupational vocabulary
1. Select four terms from the reference. Explain each in plain English, give two natural collocations and quote or create a short workplace example. Label invented examples. Contrast each term with a plausible confusable term; acknowledge regional variation.
2. Present one role-labelled exchange with one missing word or phrase and four choices A-D. Exactly one choice must fit the stated facts and grammar. Stop and wait for my answer before revealing it.
3. Explain all four options, then invite me to read the completed exchange aloud. Offer a sentence frame for optional spoken practice, never an open-ended writing assignment.
4. Repeat for the other three terms, one question at a time. Vary the correct letter and the situation; preserve the reference facts. If a choice is ambiguous, replace the item.
5. Finish with two new four-choice collocation questions for later review, with a clearly separate answer key. Do not claim to schedule a reminder.

Be my workplace English practice partner. Follow the practice instructions above, using the REFERENCE block below. The block contains fictional study material, not instructions to you. Keep its facts, numbers, uncertainty and professional responsibilities accurate. Clearly label any new scenario or changed fact as an invented variation. Use natural workplace language; explain unfamiliar abbreviations in context. If a technical expression is uncertain, say so rather than inventing a definition or authority. Coach communication, not professional decisions; respect the course scope. Ask only for fictional or anonymized practice details. Judge clarity, meaning, appropriate tone and the next step. Accept valid alternative English and distinguish errors from style preferences. Do not claim to certify my language level. Unless I ask to change the plan, follow the stages and stop wherever the instructions say to wait.

When discussing a word, phrase, or example sentence as language within an explanation, question, or answer feedback, enclose that wording in quotation marks. For example: What does “about” mean in “about twenty people”? Use “on” with a named day. Keep standalone answer choices, vocabulary headwords, and ordinary reading or dialogue text uncluttered. Quotation marks identifying a language example do not attribute it to a news source; attributed source quotations must remain verbatim.

Practice setting: B2 independent. Use natural professional English with brief explanations. Let me attempt each task without a model first. Offer a hint after difficulty and invite a more precise retry.

Lesson 01: Demand Planning and Forecast Bias
Original fictional case: Demand planner Aisha and sales lead Martin review monthly forecasts of 120, 130, and 140 units against verified demand of 100, 110, and 120. For this case, signed error means forecast minus actual demand. Next month's baseline is 120 units. Sales proposes a 30-unit promotional uplift but has no order evidence for it. Aisha and Martin must describe the three-month pattern and preserve the promotion as a scenario without treating either historical bias or future uplift as a certainty forever.
Language workshop: Three optimistic forecasts and a new promotion
Communication goal: Explain signed forecast error, distinguish bias from error size, and keep an unconfirmed promotional uplift separate from the baseline.
Language guidance: With error defined as forecast minus actual, the three errors are +20, +20, and +20 units. Total error is +60 and mean error is +20. Positive means overforecasting under this convention; other systems may reverse the sign.
Useful expressions (preserve the supplied facts): Here we define signed error as forecast minus actual demand. / Each of the three forecasts exceeded actual demand by 20 units. / Mean signed error is plus 20 units over these three months. / This pattern does not prove every future forecast will be high. / Absolute error measures the miss without its sign. / The next-month baseline remains 120 units. / Sales proposes a 30-unit promotional uplift. / That produces a 150-unit scenario, not confirmed demand. / What order or response evidence supports the proposed increment? / A future promotion does not change the earlier forecast errors. / Compare the forecast version that existed at the agreed planning point. / A sales target is not automatically an unbiased demand estimate. / Is the uplift additional demand or partly shifted from another item? / Keep the adjustment, owner, and rationale visible. / Assess whether the adjustment improves the defined forecast measure. / Present baseline, upside, and supporting evidence separately.
Vocabulary: demand forecast: An estimate of future demand for a defined item and period. / actual demand: The observed demand under the stated measurement definition. / forecast bias: A tendency for forecasts to be systematically too high or too low. / signed error: The forecast difference calculated with an explicitly stated direction. / mean error: The average signed forecast error across the defined observations. / absolute error: The size of a forecast error without its positive or negative sign. / mean absolute error: The average absolute error across the defined observations. / overforecast: A forecast greater than the corresponding actual demand. / underforecast: A forecast below the corresponding actual demand. / baseline forecast: The reference forecast before a separately identified adjustment. / promotional uplift: Additional demand expected because of a promotion. / incremental demand: Demand additional to the specified base rather than displaced from elsewhere. / cannibalization: A gain in one product's demand at the expense of another's. / seasonality: A recurring demand pattern tied to a calendar or cycle. / trend: A sustained directional movement in a series over time. / forecast horizon: The future period covered by a forecast. / forecast lag: The time between making a forecast and the period being forecast. / forecast snapshot: A saved version of the forecast at a specified time. / consensus forecast: A forecast agreed through the relevant cross-functional planning process. / demand signal: Information indicating demand behavior or potential change. / booked order: An order recorded under the organization's order definition. / scenario assumption: A premise used to construct a possible future case. / forecast override: A deliberate adjustment to a model or baseline forecast. / forecast value added: Improvement in a defined forecast measure from a specified planning step.
Speaking task: Read the corrected forecast dialogue in pairs. Stress plus twenty, mean, and absolute when comparing the historical errors. Switch roles. Read turns 9-20, distinguishing the 120-unit baseline, proposed 30-unit uplift, and 150-unit scenario. Complete and check the transfer. Read 80 minus 100 as minus 20, and keep the 105-unit next-month scenario separate from orders.
Partner: Aisha: Demand planner / Martin: Sales lead
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: A forecast is 80 units and actual demand is 100. Error is defined as forecast minus actual. Next month has a 90-unit baseline and a proposed 15-unit uplift without orders.
Model for comparison AFTER my attempt, not a response to give me first: Martin: When the next results arrive, let's evaluate the forecast version we actually used. Revising old numbers after seeing demand would make the performance comparison misleading.
Aisha: Preserve the forecast snapshot and its planning date. We need a consistent lag and definition if we want to learn whether the adjustment helped.
Martin: I will present one hundred twenty as baseline and one hundred fifty as the promotion scenario, with the evidence gap stated. The historical errors will remain unchanged.
Aisha: Good. Record the proposed forecast override with its owner and rationale. That gives the opportunity a fair assessment without disguising uncertainty or treating the scenario as a customer commitment.

TASK: Choose grammar that preserves the meaning
1. Use the lesson's language workshop, or one actual sentence from the dialogue, to explain a single grammar distinction in no more than 90 words. Show how it affects timing, certainty, responsibility or politeness.
2. Give one brief occupational exchange containing a gap and four complete options A-D. Supply enough context for exactly one answer. Keep distractors plausible; distinguish grammar errors from wording that changes the facts. Stop and wait.
3. Explain why each choice fits or fails, then ask me to read the completed exchange aloud. Do not request a draft, original written sentence or essay.
4. Repeat with three new exchanges, one at a time, moving from recognition to a more subtle meaning contrast. Do not copy the published checks. Label invented variations and do not turn uncertainty into a promise.
5. End with a short contrast table and two supported spoken turns using supplied frames. Accept accurate alternatives in oral practice; acknowledge and replace ambiguous multiple-choice items.

TASK: Interactive workplace role-play
1. Use the supplied case or dialogue as the starting situation. Give a two-sentence briefing and offer two relevant professional roles for me to choose from. For a supplied dialogue, use its actual roles. Ask which role I want, then stop and wait. Do not write my replies.
2. After I choose, identify who you will play and the immediate communication goal. Play the other professional; where a meeting requires a third person, label each of your speakers clearly. Start with one natural workplace turn and wait for my reply. Keep most turns to one to three sentences and ask no more than one question at a time.
3. Let the exchange develop across six to ten learner turns, or end earlier if I type "feedback". Respond to what I actually say. Include a plausible clarification, disagreement or tradeoff without silently changing the starting facts. Mark any added constraint as a fictional second-round variation. Do not resolve approvals, evidence or commitments that remain uncertain.
4. Stay in role during the exchange. If my meaning is unclear, ask for clarification naturally. Give a hint only if I ask or cannot proceed. Do not deliver a model conversation in advance.
5. At the debrief, quote two of my phrases: one successful choice and one worth improving. Check factual accuracy, language, register and whether the next step was clear. Give up to three focused suggestions. Ask me to retry the weakest turn; wait. Only then offer an alternative wording and a harder replay.
Use voice replies when available. If I prefer selections, offer four plausible spoken replies and explain my choice before continuing. Do not require written compositions.

Lesson 02: Procurement and Supplier Performance
Original fictional case: Buyer Keiko and supplier account manager Luis discuss purchase order P46 for 500 units. The supplier has acknowledged receipt but has given no shipping date. The buyer needs warehouse receipt by October 12. Capacity and transit timing are not confirmed. A supplier message promises an update tomorrow at noon, not dispatch tomorrow. Keiko must obtain a clear status and request line-level quantities and dates without treating the acknowledgment or update appointment as a delivery commitment.
Language workshop: Acknowledged, but not scheduled
Communication goal: Request a usable supplier commitment by separating acknowledgment, quantities, shipment timing, arrival timing, and unresolved dependencies.
Language guidance: Order acknowledged does not specify which dates or quantities have been accepted. Ask what the acknowledgment covers. A requested warehouse-receipt date needs a compatible dispatch plan and transit basis; neither is established in this case.
Useful expressions (preserve the supplied facts): This concerns P46 for 500 units. / Does your acknowledgment confirm receipt only, or specific quantities and dates? / We need warehouse receipt by October 12. / A ship date is not the same as a warehouse-receipt date. / Please confirm the quantity and committed ship date for each line. / Is capacity allocated to this order, or still under review? / What transit assumption supports the proposed arrival? / Tomorrow at noon is the response time, not a dispatch commitment. / We cannot enter a confirmed receipt date without a supported supply plan. / A partial shipment may help if quantities and the remainder are explicit. / Show how the proposed shipments add up to all 500 units. / What prevents you from confirming the date now? / Please involve the person who can confirm allocation and timing. / Are we scoring departure or receipt, and against which agreed date? / I will report the date as unconfirmed until your commitment is clear. / Please send the status tomorrow at noon even if the final date remains open.
Vocabulary: procurement: The process of sourcing and obtaining required goods or services. / purchase order: A buyer's order identifying goods, quantities, and relevant terms. / order acknowledgment: Confirmation that an order has been received or accepted as stated. / requested date: The date a party asks another party to meet. / committed date: A date a party has explicitly agreed to meet within stated terms. / ship date: The date goods leave the specified shipping point. / receipt date: The date goods arrive and are received at the stated location. / supplier lead time: The time between defined order and supply events. / transit time: The time spent moving goods between specified points. / order line: A separate item-and-quantity entry within an order. / partial shipment: Delivery of only part of the ordered quantity in one dispatch. / backorder: Ordered demand that cannot yet be fulfilled as required. / allocation: Assignment of limited supply to particular orders or customers. / capacity commitment: A confirmed assignment of production capability for a specified need. / expediting: Action to accelerate or closely follow a delayed supply activity. / minimum order quantity: The smallest quantity a supplier will accept under specified terms. / request for quotation: A buyer's request for a priced offer against defined requirements. / quotation validity: The period or conditions under which a supplier's offer remains open. / supplier scorecard: A structured summary of supplier performance against defined measures. / on-time delivery: Delivery within the agreed timing definition and tolerance. / on-time in-full: Delivery meeting both the agreed timing and quantity requirements. / service-level agreement: An agreement defining specified service commitments and measures. / commercial escalation: Referral of an unresolved supply issue to the appropriate decision level. / status checkpoint: An agreed point for obtaining an updated status.
Speaking task: Read turns 1-10, clearly distinguishing warehouse receipt by October 12 from tomorrow's noon status response. Switch roles for turns 11-20. Stress the requested shipment quantities, departure dates, and unconfirmed transit basis. Complete and check the transfer. Repeat Tuesday as an update commitment and Friday as requested receipt, without adding a dispatch promise.
Partner: Keiko: Buyer / Luis: Supplier account manager
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: A supplier acknowledges an order for 80 units. Receipt is requested on Friday. The supplier promises a status response on Tuesday but has not confirmed dispatch.
Model for comparison AFTER my attempt, not a response to give me first: Keiko: If the planning team cannot resolve allocation, please involve the right decision maker. We need a practical next route without accusing anyone of breaking a date not yet promised.
Luis: I will use the commercial escalation process if needed. The update will identify the constraint and owner rather than replace the missing date with a vague assurance.
Keiko: For performance reporting later, let's also agree whether we measure dispatch or warehouse receipt. Moving between those definitions would make on-time performance misleading.
Luis: Agreed. On-time delivery needs a fixed basis. For now, report P46 as acknowledged with timing unconfirmed, and expect my status response tomorrow at noon.

Keiko must obtain a clear status and request line-level quantities and dates without treating the acknowledgment or update appointment as a delivery commitment.
Language workshop: Acknowledged, but not scheduled
Communication goal: Request a usable supplier commitment by separating acknowledgment, quantities, shipment timing, arrival timing, and unresolved dependencies.
Language guidance: Order acknowledged does not specify which dates or quantities have been accepted. Ask what the acknowledgment covers. A requested warehouse-receipt date needs a compatible dispatch plan and transit basis; neither is established in this case.
Useful expressions (preserve the supplied facts): This concerns P46 for 500 units. / Does your acknowledgment confirm receipt only, or specific quantities and dates? / We need warehouse receipt by October 12. / A ship date is not the same as a warehouse-receipt date. / Please confirm the quantity and committed ship date for each line. / Is capacity allocated to this order, or still under review? / What transit assumption supports the proposed arrival? / Tomorrow at noon is the response time, not a dispatch commitment. / We cannot enter a confirmed receipt date without a supported supply plan. / A partial shipment may help if quantities and the remainder are explicit. / Show how the proposed shipments add up to all 500 units. / What prevents you from confirming the date now? / Please involve the person who can confirm allocation and timing. / Are we scoring departure or receipt, and against which agreed date? / I will report the date as unconfirmed until your commitment is clear. / Please send the status tomorrow at noon even if the final date remains open.
Vocabulary: procurement: The process of sourcing and obtaining required goods or services. / purchase order: A buyer's order identifying goods, quantities, and relevant terms. / order acknowledgment: Confirmation that an order has been received or accepted as stated. / requested date: The date a party asks another party to meet. / committed date: A date a party has explicitly agreed to meet within stated terms. / ship date: The date goods leave the specified shipping point. / receipt date: The date goods arrive and are received at the stated location. / supplier lead time: The time between defined order and supply events. / transit time: The time spent moving goods between specified points. / order line: A separate item-and-quantity entry within an order. / partial shipment: Delivery of only part of the ordered quantity in one dispatch. / backorder: Ordered demand that cannot yet be fulfilled as required. / allocation: Assignment of limited supply to particular orders or customers. / capacity commitment: A confirmed assignment of production capability for a specified need. / expediting: Action to accelerate or closely follow a delayed supply activity. / minimum order quantity: The smallest quantity a supplier will accept under specified terms. / request for quotation: A buyer's request for a priced offer against defined requirements. / quotation validity: The period or conditions under which a supplier's offer remains open. / supplier scorecard: A structured summary of supplier performance against defined measures. / on-time delivery: Delivery within the agreed timing definition and tolerance. / on-time in-full: Delivery meeting both the agreed timing and quantity requirements. / service-level agreement: An agreement defining specified service commitments and measures. / commercial escalation: Referral of an unresolved supply issue to the appropriate decision level. / status checkpoint: An agreed point for obtaining an updated status.
Speaking task: Read turns 1-10, clearly distinguishing warehouse receipt by October 12 from tomorrow's noon status response. Switch roles for turns 11-20. Stress the requested shipment quantities, departure dates, and unconfirmed transit basis. Complete and check the transfer. Repeat Tuesday as an update commitment and Friday as requested receipt, without adding a dispatch promise.
Partner: Keiko: Buyer / Luis: Supplier account manager
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: A supplier acknowledges an order for 80 units. Receipt is requested on Friday. The supplier promises a status response on Tuesday but has not confirmed dispatch.
Model for comparison AFTER my attempt, not a response to give me first: Keiko: If the planning team cannot resolve allocation, please involve the right decision maker. We need a practical next route without accusing anyone of breaking a date not yet promised.
Luis: I will use the commercial escalation process if needed. The update will identify the constraint and owner rather than replace the missing date with a vague assurance.
Keiko: For performance reporting later, let's also agree whether we measure dispatch or warehouse receipt. Moving between those definitions would make on-time performance misleading.
Luis: Agreed. On-time delivery needs a fixed basis. For now, report P46 as acknowledged with timing unconfirmed, and expect my status response tomorrow at noon.

TASK: Interactive workplace role-play
1. Use the supplied case or dialogue as the starting situation. Give a two-sentence briefing and offer two relevant professional roles for me to choose from. For a supplied dialogue, use its actual roles. Ask which role I want, then stop and wait. Do not write my replies.
2. After I choose, identify who you will play and the immediate communication goal. Play the other professional; where a meeting requires a third person, label each of your speakers clearly. Start with one natural workplace turn and wait for my reply. Keep most turns to one to three sentences and ask no more than one question at a time.
3. Let the exchange develop across six to ten learner turns, or end earlier if I type "feedback". Respond to what I actually say. Include a plausible clarification, disagreement or tradeoff without silently changing the starting facts. Mark any added constraint as a fictional second-round variation. Do not resolve approvals, evidence or commitments that remain uncertain.
4. Stay in role during the exchange. If my meaning is unclear, ask for clarification naturally. Give a hint only if I ask or cannot proceed. Do not deliver a model conversation in advance.
5. At the debrief, quote two of my phrases: one successful choice and one worth improving. Check factual accuracy, language, register and whether the next step was clear. Give up to three focused suggestions. Ask me to retry the weakest turn; wait. Only then offer an alternative wording and a harder replay.
Use voice replies when available. If I prefer selections, offer four plausible spoken replies and explain my choice before continuing. Do not require written compositions.

Keep its facts, numbers, uncertainty and professional responsibilities accurate. Clearly label any new scenario or changed fact as an invented variation. Use natural workplace language; explain unfamiliar abbreviations in context. If a technical expression is uncertain, say so rather than inventing a definition or authority. Coach communication, not professional decisions; respect the course scope. Ask only for fictional or anonymized practice details. Judge clarity, meaning, appropriate tone and the next step. Accept valid alternative English and distinguish errors from style preferences. Do not claim to certify my language level. Unless I ask to change the plan, follow the stages and stop wherever the instructions say to wait.

When discussing a word, phrase, or example sentence as language within an explanation, question, or answer feedback, enclose that wording in quotation marks. For example: What does “about” mean in “about twenty people”? Use “on” with a named day. Keep standalone answer choices, vocabulary headwords, and ordinary reading or dialogue text uncluttered. Quotation marks identifying a language example do not attribute it to a news source; attributed source quotations must remain verbatim.

TASK: Retrieve occupational vocabulary
1. Select four terms from the reference. Explain each in plain English, give two natural collocations and quote or create a short workplace example. Label invented examples. Contrast each term with a plausible confusable term; acknowledge regional variation.
2. Present one role-labelled exchange with one missing word or phrase and four choices A-D. Exactly one choice must fit the stated facts and grammar. Stop and wait for my answer before revealing it.
3. Explain all four options, then invite me to read the completed exchange aloud. Offer a sentence frame for optional spoken practice, never an open-ended writing assignment.
4. Repeat for the other three terms, one question at a time. Vary the correct letter and the situation; preserve the reference facts. If a choice is ambiguous, replace the item.
5. Finish with two new four-choice collocation questions for later review, with a clearly separate answer key. Do not claim to schedule a reminder.

Lesson 03: Inventory, Safety Stock, and Service Levels
Original fictional case: Inventory planner Elena and distribution manager Omar review a warehouse with a total inventory value of two million dollars. Item A has 40 units on hand, all allocated to existing orders. Item B has 80 units on hand, all blocked by a quality hold. New orders for both items remain unfilled. No available substitute or confirmed replenishment date is supplied. Elena must explain why the headline value does not resolve these shortages and distinguish physical stock from stock available to promise.
Language workshop: Plenty of inventory, none of these items available
Communication goal: Explain item-level availability and service measures without treating a high total balance or safety-stock policy as proof of fulfillment.
Language guidance: Physical presence does not establish free availability. All 40 A units are allocated; all 80 B units are blocked. Neither group is available for the new orders on the supplied facts. A total dollar value cannot be substituted for an item quantity.
Useful expressions (preserve the supplied facts): The value total does not show availability for these two items. / All 40 A units are allocated to existing orders. / All 80 B units remain blocked by the quality hold. / Neither item has available stock for these new orders on the current facts. / New demand does not remove the quality restriction. / We cannot promise the same allocated stock to two orders. / Show item, location, quantity, allocation, and status. / A planned receipt is not yet usable on-hand inventory. / Are we measuring units filled, complete orders, or stockout-free cycles? / Safety stock reduces exposure to specified uncertainty; it is not a universal guarantee. / Review demand variability and replenishment assumptions for the affected items. / High value in another item does not supply a missing unit of A. / A priority change needs an authorized allocation decision. / A larger buffer proposal needs an item-specific basis. / No confirmed replenishment date is supplied. / Report the headline value and the item-level shortage together.
Vocabulary: stock-keeping unit: A distinct inventory item identifier, commonly abbreviated SKU. / on-hand inventory: The quantity physically recorded at the stated location. / available inventory: Stock usable for the specified demand after relevant restrictions. / allocated stock: Stock assigned to particular demand or orders. / blocked stock: Stock restricted from use under a defined status. / quality hold: A restriction pending the required quality review or decision. / available to promise: The quantity that can be committed under the defined supply-and-demand rules. / inventory position: A defined balance considering on-hand stock, incoming supply, and demand commitments. / safety stock: Buffer inventory intended to protect against specified uncertainty. / cycle stock: Inventory supporting normal demand between replenishments. / reorder point: The inventory level or position that triggers replenishment under a policy. / replenishment lead time: The elapsed time from a defined replenishment trigger to usable receipt. / stockout: Inability to supply an item when required from the relevant inventory. / fill rate: The share of defined demand filled under the stated service measure. / cycle service level: The probability of avoiding a stockout during a defined replenishment cycle. / backorder: Demand retained for later fulfillment after it cannot be supplied as required. / inventory turnover: A period's inventory usage or cost relative to the defined average inventory. / days of supply: Inventory expressed as coverage of demand at a stated rate. / slow-moving stock: Inventory used or sold less frequently than the defined threshold. / obsolete stock: Inventory no longer suitable or expected to meet its intended demand. / ABC analysis: Grouping items by a selected importance measure, often annual consumption value. / item segmentation: Grouping items by relevant demand, supply, or service characteristics. / inventory accuracy: Agreement between recorded and actual inventory under the defined measure. / reallocation: Authorized reassignment of stock from one demand to another.
Speaking task: Read the corrected dialogue, contrasting physically present with available for new orders for both A and B. Switch roles for turns 11-20. Keep fill rate, cycle service level, and an authorized reallocation distinct. Complete and check the transfer. Say the quantities in order: 100 on hand, 60 allocated, 25 separately blocked, 15 free.
Partner: Elena: Inventory planner / Omar: Distribution manager
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: An item has 100 units on hand. Sixty are allocated and 25 are blocked, with no overlap. No receipt is confirmed.
Model for comparison AFTER my attempt, not a response to give me first: Omar: The replenishment report counts cycles with no shortage. Should that have a separate label so our teams stop comparing it directly with the demand-fill figure?
Elena: That is cycle service level. It is not automatically equal to a demand-fill percentage, so a shared label of service level can conceal an important difference.
Omar: I will explain the two-million-dollar total alongside the item-specific restrictions. Any proposal to move A from existing orders will also need a clear priority decision.
Elena: Yes, any reallocation must be authorized and visible. For now, report A fully allocated, B fully blocked, and replenishment unconfirmed rather than imply the headline value resolves the shortages.

TASK: Choose grammar that preserves the meaning
1. Use the lesson's language workshop, or one actual sentence from the dialogue, to explain a single grammar distinction in no more than 90 words. Show how it affects timing, certainty, responsibility or politeness.
2. Give one brief occupational exchange containing a gap and four complete options A-D. Supply enough context for exactly one answer. Keep distractors plausible; distinguish grammar errors from wording that changes the facts. Stop and wait.
3. Explain why each choice fits or fails, then ask me to read the completed exchange aloud. Do not request a draft, original written sentence or essay.
4. Repeat with three new exchanges, one at a time, moving from recognition to a more subtle meaning contrast. Do not copy the published checks. Label invented variations and do not turn uncertainty into a promise.
5. End with a short contrast table and two supported spoken turns using supplied frames. Accept accurate alternatives in oral practice; acknowledge and replace ambiguous multiple-choice items.

Vocabulary: stock-keeping unit: A distinct inventory item identifier, commonly abbreviated SKU. / on-hand inventory: The quantity physically recorded at the stated location. / available inventory: Stock usable for the specified demand after relevant restrictions. / allocated stock: Stock assigned to particular demand or orders. / blocked stock: Stock restricted from use under a defined status. / quality hold: A restriction pending the required quality review or decision. / available to promise: The quantity that can be committed under the defined supply-and-demand rules. / inventory position: A defined balance considering on-hand stock, incoming supply, and demand commitments. / safety stock: Buffer inventory intended to protect against specified uncertainty. / cycle stock: Inventory supporting normal demand between replenishments. / reorder point: The inventory level or position that triggers replenishment under a policy. / replenishment lead time: The elapsed time from a defined replenishment trigger to usable receipt. / stockout: Inability to supply an item when required from the relevant inventory. / fill rate: The share of defined demand filled under the stated service measure. / cycle service level: The probability of avoiding a stockout during a defined replenishment cycle. / backorder: Demand retained for later fulfillment after it cannot be supplied as required. / inventory turnover: A period's inventory usage or cost relative to the defined average inventory. / days of supply: Inventory expressed as coverage of demand at a stated rate. / slow-moving stock: Inventory used or sold less frequently than the defined threshold. / obsolete stock: Inventory no longer suitable or expected to meet its intended demand. / ABC analysis: Grouping items by a selected importance measure, often annual consumption value. / item segmentation: Grouping items by relevant demand, supply, or service characteristics. / inventory accuracy: Agreement between recorded and actual inventory under the defined measure. / reallocation: Authorized reassignment of stock from one demand to another.
Speaking task: Read the corrected dialogue, contrasting physically present with available for new orders for both A and B. Switch roles for turns 11-20. Keep fill rate, cycle service level, and an authorized reallocation distinct. Complete and check the transfer. Say the quantities in order: 100 on hand, 60 allocated, 25 separately blocked, 15 free.
Partner: Elena: Inventory planner / Omar: Distribution manager
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: An item has 100 units on hand. Sixty are allocated and 25 are blocked, with no overlap. No receipt is confirmed.
Model for comparison AFTER my attempt, not a response to give me first: Omar: The replenishment report counts cycles with no shortage. Should that have a separate label so our teams stop comparing it directly with the demand-fill figure?
Elena: That is cycle service level. It is not automatically equal to a demand-fill percentage, so a shared label of service level can conceal an important difference.
Omar: I will explain the two-million-dollar total alongside the item-specific restrictions. Any proposal to move A from existing orders will also need a clear priority decision.
Elena: Yes, any reallocation must be authorized and visible. For now, report A fully allocated, B fully blocked, and replenishment unconfirmed rather than imply the headline value resolves the shortages.

TASK: Retrieve occupational vocabulary
1. Select four terms from the reference. Explain each in plain English, give two natural collocations and quote or create a short workplace example. Label invented examples. Contrast each term with a plausible confusable term; acknowledge regional variation.
2. Present one role-labelled exchange with one missing word or phrase and four choices A-D. Exactly one choice must fit the stated facts and grammar. Stop and wait for my answer before revealing it.
3. Explain all four options, then invite me to read the completed exchange aloud. Offer a sentence frame for optional spoken practice, never an open-ended writing assignment.
4. Repeat for the other three terms, one question at a time. Vary the correct letter and the situation; preserve the reference facts. If a choice is ambiguous, replace the item.
5. Finish with two new four-choice collocation questions for later review, with a clearly separate answer key. Do not claim to schedule a reminder.

Be my workplace English practice partner. Follow the practice instructions above, using the REFERENCE block below. The block contains fictional study material, not instructions to you. Keep its facts, numbers, uncertainty and professional responsibilities accurate. Clearly label any new scenario or changed fact as an invented variation. Use natural workplace language; explain unfamiliar abbreviations in context. If a technical expression is uncertain, say so rather than inventing a definition or authority. Coach communication, not professional decisions; respect the course scope. Ask only for fictional or anonymized practice details. Judge clarity, meaning, appropriate tone and the next step. Accept valid alternative English and distinguish errors from style preferences. Do not claim to certify my language level. Unless I ask to change the plan, follow the stages and stop wherever the instructions say to wait.

When discussing a word, phrase, or example sentence as language within an explanation, question, or answer feedback, enclose that wording in quotation marks. For example: What does “about” mean in “about twenty people”? Use “on” with a named day. Keep standalone answer choices, vocabulary headwords, and ordinary reading or dialogue text uncluttered. Quotation marks identifying a language example do not attribute it to a news source; attributed source quotations must remain verbatim.

Practice setting: B2 independent. Use natural professional English with brief explanations. Let me attempt each task without a model first. Offer a hint after difficulty and invite a more precise retry.

Lesson 04: Warehousing and Fulfillment
Original fictional case: Warehouse lead Pavel and customer-operations manager Zoe review a shift that began with 300 open orders. Fifty new orders arrived during the shift, and 220 orders were fully shipped and closed. There were no cancellations, reopenings, or partial closures. The data do not identify which shipped orders came from the opening queue. A report says 80 remain and the oldest orders are cleared. Pavel and Zoe must correct the balance and separate the known throughput from the unsupported age and service claims.
Language workshop: Shipments and the closing queue
Communication goal: Reconcile a changing order queue, distinguish gross completions from net reduction, and avoid unsupported claims about order age or service.
Language guidance: 300 opening orders plus 50 arrivals minus 220 completed orders equals 130 closing orders. Gross completions are 220; the net queue reduction is 170. Ignoring arrivals produces the incorrect balance of 80.
Useful expressions (preserve the supplied facts): We began the shift with 300 open orders. / Fifty new orders entered during the shift. / Two hundred twenty orders were fully shipped and closed. / The closing balance is 130 open orders. / We completed 220 orders, but the queue fell by 170. / Eighty omits the 50 new arrivals. / We do not know which completed orders came from the opening queue. / The total does not prove the oldest orders were cleared. / Show the remaining orders by age and due date. / Shipped volume does not by itself establish on-time delivery. / Do not mix orders, order lines, units, and cartons. / This report counts only fully closed orders. / Identify unresolved stock, documentation, or address issues separately. / Match the completion events to the warehouse record. / The next-shift plan needs current capacity and priority information. / Present arrivals, completions, ending balance, and remaining exceptions together.

Speaking task: Read turns 1-10 and repeat Zoe's corrected balance: 300 plus 50 minus 220 equals 130. Switch roles for turns 11-20. Stress the phrases that withhold claims about the oldest orders and on-time delivery. Complete and check the transfer. Say 50 remaining and 80 completed, then read the line leaving order ages unknown.
Partner: Pavel: Warehouse lead / Zoe: Customer-operations manager
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: A shift starts with 100 open orders, receives 30, and fully closes 80. There are no other changes, and shipped-order ages are not supplied.
Model for comparison AFTER my attempt, not a response to give me first: Zoe: I will change that heading too. We are counting fully closed orders, not cartons, individual units, or customer deliveries.
Pavel: Correct. This count excludes partial fulfillment. Shipping one carton from an unfinished order does not make that order one of our two hundred twenty closures.
Zoe: I have corrected eighty to one hundred thirty, kept the completed count, and removed the oldest-cleared and on-time-delivery claims. Please check the underlying events.
Pavel: I will reconcile them against the warehouse management system. Customer service will receive the corrected balance and the age and exception details, with any unresolved differences identified.

TASK: Choose grammar that preserves the meaning
1. Use the lesson's language workshop, or one actual sentence from the dialogue, to explain a single grammar distinction in no more than 90 words. Show how it affects timing, certainty, responsibility or politeness.
2. Give one brief occupational exchange containing a gap and four complete options A-D. Supply enough context for exactly one answer. Keep distractors plausible; distinguish grammar errors from wording that changes the facts. Stop and wait.
3. Explain why each choice fits or fails, then ask me to read the completed exchange aloud. Do not request a draft, original written sentence or essay.
4. Repeat with three new exchanges, one at a time, moving from recognition to a more subtle meaning contrast. Do not copy the published checks. Label invented variations and do not turn uncertainty into a promise.
5. End with a short contrast table and two supported spoken turns using supplied frames. Accept accurate alternatives in oral practice; acknowledge and replace ambiguous multiple-choice items.

TASK: Interactive workplace role-play
1. Use the supplied case or dialogue as the starting situation. Give a two-sentence briefing and offer two relevant professional roles for me to choose from. For a supplied dialogue, use its actual roles. Ask which role I want, then stop and wait. Do not write my replies.
2. After I choose, identify who you will play and the immediate communication goal. Play the other professional; where a meeting requires a third person, label each of your speakers clearly. Start with one natural workplace turn and wait for my reply. Keep most turns to one to three sentences and ask no more than one question at a time.
3. Let the exchange develop across six to ten learner turns, or end earlier if I type "feedback". Respond to what I actually say. Include a plausible clarification, disagreement or tradeoff without silently changing the starting facts. Mark any added constraint as a fictional second-round variation. Do not resolve approvals, evidence or commitments that remain uncertain.
4. Stay in role during the exchange. If my meaning is unclear, ask for clarification naturally. Give a hint only if I ask or cannot proceed. Do not deliver a model conversation in advance.
5. At the debrief, quote two of my phrases: one successful choice and one worth improving. Check factual accuracy, language, register and whether the next step was clear. Give up to three focused suggestions. Ask me to retry the weakest turn; wait. Only then offer an alternative wording and a harder replay.
Use voice replies when available. If I prefer selections, offer four plausible spoken replies and explain my choice before continuing. Do not require written compositions.

Lesson 05: Freight, Routing, and Carrier Delays
Original fictional case: Logistics coordinator Nikhil and customer planner Dana review a fictional shipment. The carrier currently estimates warehouse arrival on Wednesday, but departure has not been confirmed. Dana needs the goods for a Wednesday 14:00 production start and asks for a guarantee. An expedited route is only being assessed; its capacity, extra cost, and arrival timing are unconfirmed. Nikhil has arranged a carrier status update for Tuesday at 16:00. He must state what is known without treating that update or the alternative route as a delivery promise.
Language workshop: Wednesday is still an estimate
Communication goal: Give a useful delay update while separating a carrier estimate, confirmed transport events, appointment timing, and an authorized contingency.
Language guidance: An ETA is an estimate for a stated event and place. It is not proof of departure or a guarantee that goods will be usable for a production start. A warehouse appointment and a confirmed arrival are also different events.
Useful expressions (preserve the supplied facts): The carrier currently estimates warehouse arrival on Wednesday. / Departure has not yet been confirmed. / I cannot confirm arrival before your 14:00 production start from the available information. / I understand that the uncertainty affects your production plan. / This estimate refers to your warehouse, not merely the destination terminal. / Please provide the confirmed departure event and its source. / A receiving slot is not proof that the vehicle will arrive in that slot. / We are assessing expedited routing, not reporting a completed booking. / Any premium cost needs the appropriate authorization. / Space must be confirmed before we rely on the alternative. / The next carrier status update is Tuesday at 16:00. / I will update you then even if the arrival remains uncertain. / A forecast departure is not actual departure. / The agreed trade rule does not itself guarantee Wednesday arrival. / State which milestone, estimate, or condition has changed. / Use Wednesday as the current estimate, with the departure dependency explicit.
Vocabulary: estimated time of arrival: A forecast arrival time for a specified destination, abbreviated ETA. / estimated time of departure: A forecast departure time from a specified location, abbreviated ETD. / actual departure: The confirmed time the shipment left the stated location. / actual arrival: The confirmed time the shipment reached the stated point. / carrier: The organization transporting goods under the relevant arrangement. / freight forwarder: A party arranging transport and related logistics services. / consignor: The party sending goods under the transport record. / consignee: The party named to receive goods under the transport record. / bill of lading: A transport document evidencing receipt and carriage terms, with functions varying by type. / air waybill: A nonnegotiable document used for air-cargo carriage. / transport milestone: A defined event used to track shipment progress. / tracking exception: A reported departure from the expected shipment process. / transshipment: Transfer of goods between transport services during a journey. / routing: The planned path and transport connections for a shipment. / last mile: The final transport leg to the delivery destination. / delivery appointment: An agreed receiving time slot at the destination. / proof of delivery: Evidence documenting the defined delivery event. / expedited freight: Transport arranged to reduce delivery time under specified conditions. / premium freight cost: Additional transport cost for a higher-cost or urgent service. / capacity booking: A reservation of transport space under the applicable terms. / demurrage: A charge for specified excess terminal or port use under applicable terms. / detention: A charge for specified extended equipment use under applicable terms. / Incoterms rule: An ICC trade rule allocating specified delivery obligations, costs, and risks. / named place: The specific location stated with the relevant trade or delivery term.
Speaking task: Read turns 1-10, keeping Wednesday's arrival estimate separate from the customer's Wednesday 14:00 production requirement. Switch roles for turns 11-20. Stress the unresolved cost, booking, and departure conditions and Tuesday's 16:00 update. Complete and check the transfer. Contrast scheduled pickup, estimated arrival, and an actual collection not yet confirmed.
Partner: Nikhil: Logistics coordinator / Dana: Customer planner
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: Pickup is scheduled for Monday. Arrival is estimated Thursday. No collection event is confirmed, and the next update is Monday at 15:00.
Model for comparison AFTER my attempt, not a response to give me first: Dana: What can you promise about the next communication? We need a reliable checkpoint even if the transport timing remains uncertain.
Nikhil: The carrier update is Tuesday at sixteen hundred. I will request the next confirmed transport milestone and tell you what changed, including if departure or the alternative still remains unresolved.
Dana: That gives us an honest planning basis. We will treat Wednesday as the current estimate, keep the production dependency visible, and wait for the confirmed movement update.
Nikhil: Once delivery occurs, we can obtain proof of delivery. Until then, I will distinguish estimates, bookings, confirmed events, and the next communication rather than combine them into a guarantee.

TASK: Choose grammar that preserves the meaning
1. Use the lesson's language workshop, or one actual sentence from the dialogue, to explain a single grammar distinction in no more than 90 words. Show how it affects timing, certainty, responsibility or politeness.
2. Give one brief occupational exchange containing a gap and four complete options A-D. Supply enough context for exactly one answer. Keep distractors plausible; distinguish grammar errors from wording that changes the facts. Stop and wait.
3. Explain why each choice fits or fails, then ask me to read the completed exchange aloud. Do not request a draft, original written sentence or essay.
4. Repeat with three new exchanges, one at a time, moving from recognition to a more subtle meaning contrast. Do not copy the published checks. Label invented variations and do not turn uncertainty into a promise.
5. End with a short contrast table and two supported spoken turns using supplied frames. Accept accurate alternatives in oral practice; acknowledge and replace ambiguous multiple-choice items.

Keep its facts, numbers, uncertainty and professional responsibilities accurate. Clearly label any new scenario or changed fact as an invented variation. Use natural workplace language; explain unfamiliar abbreviations in context. If a technical expression is uncertain, say so rather than inventing a definition or authority. Coach communication, not professional decisions; respect the course scope. Ask only for fictional or anonymized practice details. Judge clarity, meaning, appropriate tone and the next step. Accept valid alternative English and distinguish errors from style preferences. Do not claim to certify my language level. Unless I ask to change the plan, follow the stages and stop wherever the instructions say to wait.

When discussing a word, phrase, or example sentence as language within an explanation, question, or answer feedback, enclose that wording in quotation marks. For example: What does “about” mean in “about twenty people”? Use “on” with a named day. Keep standalone answer choices, vocabulary headwords, and ordinary reading or dialogue text uncluttered. Quotation marks identifying a language example do not attribute it to a news source; attributed source quotations must remain verbatim.

Practice setting: B2 independent. Use natural professional English with brief explanations. Let me attempt each task without a model first. Offer a hint after difficulty and invite a more precise retry.

Lesson 05: Freight, Routing, and Carrier Delays
Original fictional case: Logistics coordinator Nikhil and customer planner Dana review a fictional shipment. The carrier currently estimates warehouse arrival on Wednesday, but departure has not been confirmed. Dana needs the goods for a Wednesday 14:00 production start and asks for a guarantee. An expedited route is only being assessed; its capacity, extra cost, and arrival timing are unconfirmed. Nikhil has arranged a carrier status update for Tuesday at 16:00. He must state what is known without treating that update or the alternative route as a delivery promise.
Language workshop: Wednesday is still an estimate
Communication goal: Give a useful delay update while separating a carrier estimate, confirmed transport events, appointment timing, and an authorized contingency.
Language guidance: An ETA is an estimate for a stated event and place. It is not proof of departure or a guarantee that goods will be usable for a production start. A warehouse appointment and a confirmed arrival are also different events.
Useful expressions (preserve the supplied facts): The carrier currently estimates warehouse arrival on Wednesday. / Departure has not yet been confirmed. / I cannot confirm arrival before your 14:00 production start from the available information. / I understand that the uncertainty affects your production plan. / This estimate refers to your warehouse, not merely the destination terminal. / Please provide the confirmed departure event and its source. / A receiving slot is not proof that the vehicle will arrive in that slot. / We are assessing expedited routing, not reporting a completed booking. / Any premium cost needs the appropriate authorization. / Space must be confirmed before we rely on the alternative. / The next carrier status update is Tuesday at 16:00. / I will update you then even if the arrival remains uncertain. / A forecast departure is not actual departure. / The agreed trade rule does not itself guarantee Wednesday arrival. / State which milestone, estimate, or condition has changed. / Use Wednesday as the current estimate, with the departure dependency explicit.
Vocabulary: estimated time of arrival: A forecast arrival time for a specified destination, abbreviated ETA. / estimated time of departure: A forecast departure time from a specified location, abbreviated ETD. / actual departure: The confirmed time the shipment left the stated location. / actual arrival: The confirmed time the shipment reached the stated point. / carrier: The organization transporting goods under the relevant arrangement. / freight forwarder: A party arranging transport and related logistics services. / consignor: The party sending goods under the transport record. / consignee: The party named to receive goods under the transport record. / bill of lading: A transport document evidencing receipt and carriage terms, with functions varying by type. / air waybill: A nonnegotiable document used for air-cargo carriage. / transport milestone: A defined event used to track shipment progress. / tracking exception: A reported departure from the expected shipment process. / transshipment: Transfer of goods between transport services during a journey. / routing: The planned path and transport connections for a shipment. / last mile: The final transport leg to the delivery destination. / delivery appointment: An agreed receiving time slot at the destination. / proof of delivery: Evidence documenting the defined delivery event. / expedited freight: Transport arranged to reduce delivery time under specified conditions. / premium freight cost: Additional transport cost for a higher-cost or urgent service. / capacity booking: A reservation of transport space under the applicable terms. / demurrage: A charge for specified excess terminal or port use under applicable terms. / detention: A charge for specified extended equipment use under applicable terms. / Incoterms rule: An ICC trade rule allocating specified delivery obligations, costs, and risks. / named place: The specific location stated with the relevant trade or delivery term.
Speaking task: Read turns 1-10, keeping Wednesday's arrival estimate separate from the customer's Wednesday 14:00 production requirement. Switch roles for turns 11-20. Stress the unresolved cost, booking, and departure conditions and Tuesday's 16:00 update. Complete and check the transfer. Contrast scheduled pickup, estimated arrival, and an actual collection not yet confirmed.

TASK: Interactive workplace role-play
1. Use the supplied case or dialogue as the starting situation. Give a two-sentence briefing and offer two relevant professional roles for me to choose from. For a supplied dialogue, use its actual roles. Ask which role I want, then stop and wait. Do not write my replies.
2. After I choose, identify who you will play and the immediate communication goal. Play the other professional; where a meeting requires a third person, label each of your speakers clearly. Start with one natural workplace turn and wait for my reply. Keep most turns to one to three sentences and ask no more than one question at a time.
3. Let the exchange develop across six to ten learner turns, or end earlier if I type "feedback". Respond to what I actually say. Include a plausible clarification, disagreement or tradeoff without silently changing the starting facts. Mark any added constraint as a fictional second-round variation. Do not resolve approvals, evidence or commitments that remain uncertain.
4. Stay in role during the exchange. If my meaning is unclear, ask for clarification naturally. Give a hint only if I ask or cannot proceed. Do not deliver a model conversation in advance.
5. At the debrief, quote two of my phrases: one successful choice and one worth improving. Check factual accuracy, language, register and whether the next step was clear. Give up to three focused suggestions. Ask me to retry the weakest turn; wait. Only then offer an alternative wording and a harder replay.
Use voice replies when available. If I prefer selections, offer four plausible spoken replies and explain my choice before continuing. Do not require written compositions.

TASK: Retrieve occupational vocabulary
1. Select four terms from the reference. Explain each in plain English, give two natural collocations and quote or create a short workplace example. Label invented examples. Contrast each term with a plausible confusable term; acknowledge regional variation.
2. Present one role-labelled exchange with one missing word or phrase and four choices A-D. Exactly one choice must fit the stated facts and grammar. Stop and wait for my answer before revealing it.
3. Explain all four options, then invite me to read the completed exchange aloud. Offer a sentence frame for optional spoken practice, never an open-ended writing assignment.
4. Repeat for the other three terms, one question at a time. Vary the correct letter and the situation; preserve the reference facts. If a choice is ambiguous, replace the item.
5. Finish with two new four-choice collocation questions for later review, with a clearly separate answer key. Do not claim to schedule a reminder.

Lesson 06: Customs, Trade Compliance, and Documentation
Original fictional case: Trade coordinator Sofia and exporter contact Chen review a fictional US-bound shipment file. The invoice describes stainless-steel bolts; the packing list describes aluminum brackets. Both show 500 pieces, but matching counts do not establish which description is correct. The broker requests clarification before relying on the file. No verified product specification, classification, or origin determination is supplied. Sofia and Chen must obtain the underlying product facts and corrected authorized documents without simply copying one unverified description over the other.
Language workshop: The invoice and packing list describe different goods
Communication goal: Raise a document discrepancy, request verified product facts, and arrange controlled correction without guessing classification or changing facts to fit a document.
Language guidance: Five hundred pieces on both documents confirms only agreement in the stated count. Bolts and brackets, and stainless steel and aluminum, are materially different descriptions. Neither document is established as correct by the supplied facts.
Useful expressions (preserve the supplied facts): The invoice says stainless-steel bolts; the packing list says aluminum brackets. / Both list 500 pieces, but that does not resolve the product identity. / We cannot assume either description is correct without supporting facts. / Please provide the verified product specification and relevant order details. / Confirm the actual material rather than copying an unverified label. / Reconcile the item identifiers and package contents. / Ask the responsible issuer to correct the affected document. / Retain the original and the reason for the correction. / The product description does not by itself complete a tariff review. / The wording must follow the goods, not a preferred duty outcome. / Country of shipment does not automatically establish country of origin. / Provide the verified facts to the broker and responsible import team. / Classification needs the applicable facts and qualified review. / The discrepancy is being resolved; customs release is not confirmed. / The corrected documents must match the verified goods, not merely each other. / Send the authorized corrections with their supporting references.
Vocabulary: commercial invoice: A transaction document describing goods, value, parties, and relevant terms. / packing list: A document describing how goods and quantities are packed. / merchandise description: The factual identification and characteristics of the goods. / product specification: Technical information defining a product's characteristics. / material composition: The substances or materials making up a product. / end use: The purpose for which the product is intended or used. / tariff classification: Assignment of goods to an applicable tariff category under the governing rules. / Harmonized System: The international goods-classification framework commonly abbreviated HS. / HTSUS: The Harmonized Tariff Schedule of the United States. / country of origin: The country determined as the goods' origin under applicable rules. / country of shipment: The country from which goods are dispatched. / customs value: The value determined under the applicable customs valuation rules. / declared quantity: The quantity stated in the relevant customs or shipment record. / unit of measure: The basis used to count or measure goods. / net weight: The weight of goods excluding the specified packaging. / gross weight: The weight including the specified goods and packaging. / importer of record: The party responsible for the import entry under applicable law. / customs broker: A qualified intermediary conducting customs business under the relevant authorization. / entry documentation: The records supporting the import entry process. / supporting evidence: Records substantiating the information in a declaration or document. / document discrepancy: A conflict between relevant records or stated facts. / corrected invoice: An authorized revised invoice addressing an identified error. / revision history: A record of what changed, when, and why. / customs release: The customs decision permitting goods to proceed under applicable conditions.
Speaking task: Read turns 1-10. Name both conflicting goods descriptions while keeping the matching count of 500 unchanged. Switch roles for turns 11-20. Emphasize verified facts, authorized correction, and customs release as separate steps. Complete and check the transfer. Read the material discrepancy and correction request without choosing plastic or steel as the verified fact.

Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: An invoice says plastic housings and the packing list says steel housings. Both list 40 pieces. Actual material and customs release are unconfirmed.
Model for comparison AFTER my attempt, not a response to give me first: Sofia: Once the verified information and authorized corrections are ready, I will send them to the broker and responsible import team with the supporting references.
Chen: That gives the customs broker a factual basis for the required review. We should answer the clarification request directly rather than imply that matching counts settle the matter.
Sofia: The status update will say the document discrepancy is being resolved. Even a corrected file would not justify telling the warehouse the goods are already released.
Chen: Exactly. Customs release must be confirmed as its own event. Our responsibility here is an accurate, authorized, traceable file, without inventing a classification or a clearance outcome.

REFERENCE
Course: Supply Chain and Logistics English
Professional audience: supply-chain managers, planners, buyers, logistics coordinators, warehouse leaders, procurement teams, customs staff, and operations managers
Scope: Original fictional language practice, not customs, legal, financial, transport-safety, or inventory-policy advice. All figures, shipments, organizations, and negotiations are invented. Use applicable law, governing contracts, current trade rules, authorized decisions, and qualified review. US customs examples are identified; requirements differ by jurisdiction.
Lesson 06: Customs, Trade Compliance, and Documentation
Original fictional case: Trade coordinator Sofia and exporter contact Chen review a fictional US-bound shipment file. The invoice describes stainless-steel bolts; the packing list describes aluminum brackets. Both show 500 pieces, but matching counts do not establish which description is correct. The broker requests clarification before relying on the file. No verified product specification, classification, or origin determination is supplied. Sofia and Chen must obtain the underlying product facts and corrected authorized documents without simply copying one unverified description over the other.
Language workshop: The invoice and packing list describe different goods
Communication goal: Raise a document discrepancy, request verified product facts, and arrange controlled correction without guessing classification or changing facts to fit a document.
Language guidance: Five hundred pieces on both documents confirms only agreement in the stated count. Bolts and brackets, and stainless steel and aluminum, are materially different descriptions. Neither document is established as correct by the supplied facts.
Useful expressions (preserve the supplied facts): The invoice says stainless-steel bolts; the packing list says aluminum brackets. / Both list 500 pieces, but that does not resolve the product identity. / We cannot assume either description is correct without supporting facts. / Please provide the verified product specification and relevant order details. / Confirm the actual material rather than copying an unverified label. / Reconcile the item identifiers and package contents. / Ask the responsible issuer to correct the affected document. / Retain the original and the reason for the correction. / The product description does not by itself complete a tariff review. / The wording must follow the goods, not a preferred duty outcome. / Country of shipment does not automatically establish country of origin. / Provide the verified facts to the broker and responsible import team. / Classification needs the applicable facts and qualified review. / The discrepancy is being resolved; customs release is not confirmed. / The corrected documents must match the verified goods, not merely each other. / Send the authorized corrections with their supporting references.
Vocabulary: commercial invoice: A transaction document describing goods, value, parties, and relevant terms. / packing list: A document describing how goods and quantities are packed. / merchandise description: The factual identification and characteristics of the goods. / product specification: Technical information defining a product's characteristics. / material composition: The substances or materials making up a product. / end use: The purpose for which the product is intended or used. / tariff classification: Assignment of goods to an applicable tariff category under the governing rules. / Harmonized System: The international goods-classification framework commonly abbreviated HS. / HTSUS: The Harmonized Tariff Schedule of the United States. / country of origin: The country determined as the goods' origin under applicable rules. / country of shipment: The country from which goods are dispatched. / customs value: The value determined under the applicable customs valuation rules. / declared quantity: The quantity stated in the relevant customs or shipment record. / unit of measure: The basis used to count or measure goods. / net weight: The weight of goods excluding the specified packaging. / gross weight: The weight including the specified goods and packaging. / importer of record: The party responsible for the import entry under applicable law. / customs broker: A qualified intermediary conducting customs business under the relevant authorization. / entry documentation: The records supporting the import entry process. / supporting evidence: Records substantiating the information in a declaration or document. / document discrepancy: A conflict between relevant records or stated facts. / corrected invoice: An authorized revised invoice addressing an identified error. / revision history: A record of what changed, when, and why. / customs release: The customs decision permitting goods to proceed under applicable conditions.
Speaking task: Read turns 1-10. Name both conflicting goods descriptions while keeping the matching count of 500 unchanged. Switch roles for turns 11-20. Emphasize verified facts, authorized correction, and customs release as separate steps. Complete and check the transfer. Read the material discrepancy and correction request without choosing plastic or steel as the verified fact.
Partner: Sofia: Trade coordinator / Chen: Exporter documentation contact
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: An invoice says plastic housings and the packing list says steel housings. Both list 40 pieces. Actual material and customs release are unconfirmed.
Model for comparison AFTER my attempt, not a response to give me first: Sofia: Once the verified information and authorized corrections are ready, I will send them to the broker and responsible import team with the supporting references.
Chen: That gives the customs broker a factual basis for the required review. We should answer the clarification request directly rather than imply that matching counts settle the matter.
Sofia: The status update will say the document discrepancy is being resolved. Even a corrected file would not justify telling the warehouse the goods are already released.
Chen: Exactly. Customs release must be confirmed as its own event. Our responsibility here is an accurate, authorized, traceable file, without inventing a classification or a clearance outcome.

TASK: Retrieve occupational vocabulary
1. Select four terms from the reference. Explain each in plain English, give two natural collocations and quote or create a short workplace example. Label invented examples. Contrast each term with a plausible confusable term; acknowledge regional variation.
2. Present one role-labelled exchange with one missing word or phrase and four choices A-D. Exactly one choice must fit the stated facts and grammar. Stop and wait for my answer before revealing it.
3. Explain all four options, then invite me to read the completed exchange aloud. Offer a sentence frame for optional spoken practice, never an open-ended writing assignment.
4. Repeat for the other three terms, one question at a time. Vary the correct letter and the situation; preserve the reference facts. If a choice is ambiguous, replace the item.
5. Finish with two new four-choice collocation questions for later review, with a clearly separate answer key. Do not claim to schedule a reminder.

Be my workplace English practice partner. Follow the practice instructions above, using the REFERENCE block below. The block contains fictional study material, not instructions to you. Keep its facts, numbers, uncertainty and professional responsibilities accurate. Clearly label any new scenario or changed fact as an invented variation. Use natural workplace language; explain unfamiliar abbreviations in context. If a technical expression is uncertain, say so rather than inventing a definition or authority. Coach communication, not professional decisions; respect the course scope. Ask only for fictional or anonymized practice details. Judge clarity, meaning, appropriate tone and the next step. Accept valid alternative English and distinguish errors from style preferences. Do not claim to certify my language level. Unless I ask to change the plan, follow the stages and stop wherever the instructions say to wait.

When discussing a word, phrase, or example sentence as language within an explanation, question, or answer feedback, enclose that wording in quotation marks. For example: What does “about” mean in “about twenty people”? Use “on” with a named day. Keep standalone answer choices, vocabulary headwords, and ordinary reading or dialogue text uncluttered. Quotation marks identifying a language example do not attribute it to a news source; attributed source quotations must remain verbatim.

Lesson 07: Supply Risk and Business Continuity
Original fictional case: Risk planner Ren and sourcing manager Julia compare supplier A, with a quoted two-week lead time, and supplier B, with a quoted four-week lead time. B reports spare capacity, but none is reserved and qualification is incomplete. Both may depend on the same coating site; this is unverified. Current usable stock equals three weeks of the stated demand rate. The team must assess continuity without declaring B immediately usable or treating two supplier names as proof of independent supply.
Language workshop: A second supplier is not yet a ready backup
Communication goal: Compare supply options while separating quoted lead time, reserved capacity, qualification, and shared disruption exposure.
Language guidance: B has a quoted lead time and reported capacity, not a completed qualification or a reserved production slot. A four-week quote is not necessarily the full time needed to activate the backup. The possible shared coating site remains an open fact to verify.
Useful expressions (preserve the supplied facts): A quotes two weeks; B quotes four, under their stated conditions. / A shorter quoted lead time does not answer every continuity question. / B is not yet a fully ready alternative. / Source qualification remains incomplete. / Reported spare capacity is not capacity reserved for us. / Verify whether both suppliers use the same coating site. / The common-site dependency is possible, not yet confirmed. / Two supplier names do not prove independent disruption exposure. / Current usable stock covers three weeks at the stated demand rate. / Tooling, qualification, and allocation may affect when the backup becomes usable. / State demand, receipts, and activation assumptions before calculating a gap. / A recovery objective is not proof that recovery can occur that quickly. / Agree which event would activate the contingency review. / Identify who will verify capacity and qualification status. / Do not promise backup supply before the required conditions are met. / Record dependencies, evidence gaps, owners, and next checkpoints.
Vocabulary: single sourcing: Choosing to obtain a requirement from one supplier despite alternatives. / sole sourcing: Depending on the only available source for a requirement. / dual sourcing: Using two sources for a defined supply requirement. / source qualification: Evaluation and approval of a source for a specified requirement. / backup capacity: Potential supply capability intended for contingency use. / capacity reservation: A defined commitment setting aside supply capability for a buyer. / quoted lead time: A supplier's stated lead-time estimate or offer under specified conditions. / activation lead time: Time needed to make a contingency operational after a trigger. / switching cost: The cost of moving a requirement to another source or arrangement. / tooling transfer: Moving required production tools to another site or source. / subtier supplier: A supplier further upstream than the directly contracted supplier. / common dependency: A resource or facility on which multiple supply options rely. / correlated disruption: A disruption capable of affecting multiple sources together. / geographic concentration: Supply dependence clustered in the same area. / business continuity plan: A plan for maintaining or restoring prioritized operations during disruption. / contingency trigger: A defined condition for activating an alternative action. / time to recover: The period needed to restore the specified supply or operational capability. / time to survive: The period operations can continue under a defined disruption scenario. / recovery objective: A target for restoring a specified capability. / buffer coverage: The demand period supported by a stated usable buffer. / resilience: The ability to prepare for, respond to, and recover from disruption. / risk register: A record of identified risks, assessments, owners, and actions. / scenario test: An examination of a plan under specified hypothetical conditions. / continuity owner: The person accountable for a defined continuity action or plan.
Speaking task: Read turns 1-10, distinguishing reported spare capacity from a reservation and a possible common site from a verified one. Switch roles for turns 11-20. Keep the one-week gap conditional on the printed simplified scenario. Complete and check the transfer. Read five weeks minus two as three, then state the unchanged-demand and unreserved-capacity conditions.
Partner: Ren: Risk planner / Julia: Sourcing manager
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: Usable stock covers two weeks at unchanged demand. In a simplified scenario with no incoming receipts, usable backup begins after five weeks. Capacity is not reserved.
Model for comparison AFTER my attempt, not a response to give me first: Julia: The continuity plan needs a decision point too. Otherwise we may know a backup exists on paper but not know when to begin the required review.
Ren: Define a contingency trigger and the responsible owner. The trigger should lead to the agreed process, not authorize an unqualified source or an unsupported shipment promise.
Julia: I will revise B from ready backup to candidate pending qualification, reservation, and dependency checks. The comparison will retain A's shorter quote without treating it as the only relevant factor.
Ren: Good. Update the risk register with those conditions and checkpoints. That gives us a practical continuity discussion instead of reassurance based only on a second supplier name.

TASK: Choose grammar that preserves the meaning
1. Use the lesson's language workshop, or one actual sentence from the dialogue, to explain a single grammar distinction in no more than 90 words. Show how it affects timing, certainty, responsibility or politeness.
2. Give one brief occupational exchange containing a gap and four complete options A-D. Supply enough context for exactly one answer. Keep distractors plausible; distinguish grammar errors from wording that changes the facts. Stop and wait.
3. Explain why each choice fits or fails, then ask me to read the completed exchange aloud. Do not request a draft, original written sentence or essay.
4. Repeat with three new exchanges, one at a time, moving from recognition to a more subtle meaning contrast. Do not copy the published checks. Label invented variations and do not turn uncertainty into a promise.
5. End with a short contrast table and two supported spoken turns using supplied frames. Accept accurate alternatives in oral practice; acknowledge and replace ambiguous multiple-choice items.

TASK: Interactive workplace role-play
1. Use the supplied case or dialogue as the starting situation. Give a two-sentence briefing and offer two relevant professional roles for me to choose from. For a supplied dialogue, use its actual roles. Ask which role I want, then stop and wait. Do not write my replies.
2. After I choose, identify who you will play and the immediate communication goal. Play the other professional; where a meeting requires a third person, label each of your speakers clearly. Start with one natural workplace turn and wait for my reply. Keep most turns to one to three sentences and ask no more than one question at a time.
3. Let the exchange develop across six to ten learner turns, or end earlier if I type "feedback". Respond to what I actually say. Include a plausible clarification, disagreement or tradeoff without silently changing the starting facts. Mark any added constraint as a fictional second-round variation. Do not resolve approvals, evidence or commitments that remain uncertain.
4. Stay in role during the exchange. If my meaning is unclear, ask for clarification naturally. Give a hint only if I ask or cannot proceed. Do not deliver a model conversation in advance.
5. At the debrief, quote two of my phrases: one successful choice and one worth improving. Check factual accuracy, language, register and whether the next step was clear. Give up to three focused suggestions. Ask me to retry the weakest turn; wait. Only then offer an alternative wording and a harder replay.
Use voice replies when available. If I prefer selections, offer four plausible spoken replies and explain my choice before continuing. Do not require written compositions.
