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.

REFERENCE
Course: Corporate Strategy English
Professional audience: corporate strategy, CEO office, transformation, corporate development, strategic finance, product strategy, and internal consulting teams
Scope: Original fictional language practice, not investment, legal, accounting, valuation, or transaction advice. Figures are teaching assumptions, not forecasts. Actual strategic decisions require verified company facts, appropriate analysis, authorized governance, and qualified review where needed.
Lesson 01: Strategy Role, Problem Framing, and Executive Diagnosis
Original fictional case: Executive sponsor Daniel asks strategy lead Rina for a growth strategy. Last year the business reported $20 million revenue and $2 million operating profit. The sponsor has not chosen whether the primary objective is revenue growth, operating-profit improvement, or entry into a new market. No target, horizon, or spending limit has been agreed. A workshop is scheduled for Monday. Rina must establish the decision question and missing inputs rather than assume that an acquisition or a 20% revenue target has already been authorized.
Language workshop: Growth is an ambition, not yet a clear assignment
Communication goal: Clarify an executive mandate before selecting a growth option or commissioning broad analysis.
Language guidance: Revenue and operating profit are different measures. The historical figures imply a 10% operating margin on the stated basis, but do not tell the team which outcome to prioritize. A growth label should not silently become a revenue target, acquisition mandate, or permission to spend.
Useful expressions (preserve the supplied facts): Which outcome should the growth strategy prioritize? / Last year revenue was $20 million and operating profit was $2 million. / Revenue growth and profit improvement can point to different choices. / Over what period should we evaluate the result? / We have not yet agreed a spending limit or scope. / Acquisition is an option to assess, not the mandate itself. / Who will approve the objective and the final recommendation? / Let us confirm the mandate before Monday's options discussion. / What evidence explains the gap between current performance and the desired outcome? / I will label that premise as unverified until its owner confirms it. / We should test the cause before designing the response. / Which questions would actually change the decision? / A 20% revenue figure has not been approved as the goal. / The initial option set should not assume one route is inevitable. / We have a historical baseline, but no agreed target or horizon. / Does this question capture the choice you need the team to support?
Vocabulary: strategic mandate: The authorized purpose and boundaries of a strategy assignment. / problem statement: A precise description of the issue to be addressed. / decision question: The choice the analysis is intended to support. / executive sponsor: The senior person accountable for backing and directing an initiative. / objective: The outcome an effort is intended to achieve. / target: A specified desired level of performance or outcome. / baseline: The starting reference against which a change is assessed. / time horizon: The period over which a decision or outcome is evaluated. / scope boundary: A limit on what the assignment includes. / constraint: A condition restricting feasible choices. / diagnosis: An evidence-based explanation of the central problem or challenge. / symptom: An observed sign that may have more than one underlying cause. / hypothesis: A proposition requiring testing against evidence. / issue tree: A structured breakdown of a problem into questions. / driver analysis: Examination of factors contributing to an observed result. / evidence gap: Missing information needed to support a conclusion. / assumption register: A record of premises, evidence status, and owners. / fact base: The verified information supporting an analysis. / stakeholder map: A description of relevant parties and their interests or roles. / alignment: Shared understanding of the relevant goal or decision. / decision rights: The authority to make or approve specified choices. / success criterion: A condition used to determine whether the effort meets its goal. / strategic option: A distinct possible course of action. / recommendation: A proposed course of action supported by reasoning.
Speaking task: Check the cloze key, then read the sponsor discussion. State $20 million revenue and $2 million operating profit as last year's baseline, not next year's targets. Switch roles for the mandate questions. Preserve the unresolved objective, horizon, scope, spending limit, and decision rights instead of inventing answers. Complete and check the overseas-office exchange. Contrast an option with an objective, and retain the absence of lease authority.
Partner: Daniel: Executive sponsor / Rina: Strategy 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 sponsor proposes opening an overseas office but has not stated the intended business outcome or budget. The team has no authority to sign a lease.
Model for comparison AFTER my attempt, not a response to give me first: Daniel: I should confirm the outcome and limits, then the team can compare routes. Who else needs a decision role should be explicit as well.
Rina: Yes. Clear decision rights will prevent a workshop preference from being reported as authorization. We can name the sponsor decisions separately from the analytical work assigned to the team.
Daniel: Send me a one-page mandate before Monday. Leave the target open for my decision; the twenty-percent figure mentioned earlier was not an agreement.
Rina: I will mark the open success criteria and frame the decision for confirmation. The workshop can then compare options against the same objective instead of debating several different meanings of growth.

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: Strategic Choices: Ambition, Where to Play, How to Win, and Tradeoffs
Original fictional case: For the next quarter, a service business has 160 specialist-weeks available after existing commitments. Improving the core service requires 120 specialist-weeks; entering an adjacent segment requires 100. Both need the same specialists. A draft strategy says to deliver both in full next quarter without explaining the 60-week shortfall. No additional hiring, outsourcing, or reduced scope has been approved. Strategy manager Sana and business-unit head Victor must compare choices and sequencing without treating ambition as extra capacity.
Language workshop: Two priorities competing for the same specialist team
Communication goal: Make a strategic trade-off explicit when two attractive initiatives cannot both fit the available capacity.
Language guidance: The resource gap is 60 specialist-weeks, not 60 people and not automatically a cash budget of any particular size. Available capacity already excludes existing commitments. Do not count the same specialist time twice or treat an unapproved recruitment idea as immediately usable capacity.
Useful expressions (preserve the supplied facts): Both initiatives may have value, but the current plan does not fit. / The two initiatives require 220 specialist-weeks against 160 available. / We are short by 60 specialist-weeks. / Both proposals depend on the same specialist team. / Which outcome takes priority if we cannot deliver both in full? / We can compare sequencing, reduced scope, or a properly approved capacity plan. / No extra hiring or outsourcing has been approved. / The final plan must name what happens now and what waits. / Which segment are we choosing to serve first? / Why would customers choose us in that segment? / Operational improvement and a new market position are not identical choices. / Funding this route means delaying or reducing another use of the team. / New staff would need realistic onboarding and availability assumptions. / A smaller scope should answer a defined question. / The strategy should state what we are not committing to this quarter. / These figures are specialist-weeks, not headcount.
Vocabulary: strategic ambition: The overall level or direction of desired achievement. / where to play: The markets, customers, or activities selected for competition. / how to win: The proposed basis for succeeding in the chosen arena. / trade-off: A choice that sacrifices one benefit to obtain another. / opportunity cost: The value of the next-best alternative forgone. / capacity constraint: A limit imposed by the amount of usable resources. / resource envelope: The total resources available within defined boundaries. / core business: The established activities central to the company's current operation. / adjacency: A related market or activity beyond the current core. / strategic focus: Concentration on a selected set of choices and priorities. / differentiation: A relevant distinction that gives customers a reason to choose an offering. / cost advantage: A relative cost position that can support competitive performance. / competitive positioning: The chosen place and proposition relative to alternatives. / activity system: A set of mutually supporting activities that deliver a strategy. / strategic fit: Compatibility among choices, capabilities, and the intended direction. / operational effectiveness: Performing activities well relative to their required standard or alternatives. / cannibalization: A new offering reducing demand or revenue for the company's existing offering. / sequencing: Ordering initiatives over time according to priorities and dependencies. / phased rollout: Introduction through defined stages rather than all at once. / minimum viable scope: The smallest scope sufficient for the specified purpose or learning goal. / deprioritization: A decision to give an activity less priority or delay it. / stop-doing list: An explicit set of activities to discontinue or suspend. / resource bottleneck: A resource whose limited availability restricts overall progress. / commitment: An agreed allocation or obligation rather than a tentative proposal.
Speaking task: After checking the answers, read Victor and Sana's exchange. Stress combined demand: 120 plus 100 is 220 specialist-weeks against 160 available. Switch roles for turns 11-20. Keep the forty-week pilot as an option requiring design, not an approved substitute for the full launch. Complete the two-pilot exchange and check the key. Read 105 required, 90 available, and 15 short clearly, retaining analyst-days as the unit.
Partner: Sana: Strategy manager / Victor: Business-unit head
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 team has 90 analyst-days available. Pilot A needs 55 days and Pilot B needs 50. No additional capacity or scope reduction has been approved.
Model for comparison AFTER my attempt, not a response to give me first: Victor: I also want a page showing what stops. Otherwise another priority will arrive and we will have this argument again.
Sana: I will include a stop-doing list with the consequences of each choice. Removing work needs a decision too; it cannot remain an unnamed assumption.
Victor: Bring the customer evidence, expected value, and feasible scopes to the meeting. Leave the full-delivery promise out until we choose.
Sana: Then we can record a deliverable commitment: one resource plan, named priorities, and explicit timing. The sixty-week gap stays visible until a decision resolves it.

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: Strategic Choices: Ambition, Where to Play, How to Win, and Tradeoffs
Original fictional case: For the next quarter, a service business has 160 specialist-weeks available after existing commitments. Improving the core service requires 120 specialist-weeks; entering an adjacent segment requires 100. Both need the same specialists. A draft strategy says to deliver both in full next quarter without explaining the 60-week shortfall. No additional hiring, outsourcing, or reduced scope has been approved. Strategy manager Sana and business-unit head Victor must compare choices and sequencing without treating ambition as extra capacity.
Language workshop: Two priorities competing for the same specialist team
Communication goal: Make a strategic trade-off explicit when two attractive initiatives cannot both fit the available capacity.
Language guidance: The resource gap is 60 specialist-weeks, not 60 people and not automatically a cash budget of any particular size. Available capacity already excludes existing commitments. Do not count the same specialist time twice or treat an unapproved recruitment idea as immediately usable capacity.

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: Industry Structure, Competitive Dynamics, and Profit Pools
Original fictional case: A presentation labels $10 billion of annual industry spending as the company's immediate opportunity. The company can serve only a segment estimated at $400 million, of which $120 million lies in its current service geography. A separate model assumes a 10% share of that $120 million, implying $12 million annual revenue, but the share assumption has not been validated. No segment profit data or customer-switching evidence are supplied. Strategy analyst Kai and commercial director Yara must rebuild the claim without turning an estimate into a forecast.
Language workshop: A large industry is not the company's available market
Communication goal: Narrow a market-size claim and distinguish addressable spending, assumed capture, and available profit.
Language guidance: TAM means total addressable market; SAM, serviceable available market; SOM, serviceable obtainable market. Define each boundary. Industry spending is not automatically the TAM for a narrow offer, and an assumed share is not demonstrated demand.
Useful expressions (preserve the supplied facts): The $10 billion figure includes demand we cannot currently serve. / The relevant segment is $400 million, with $120 million in our geography. / Ten percent capture is a modeling input, not a validated result. / That assumption implies $12 million annual revenue. / Market spending does not establish the profit available to us. / What would make accounts switch from their current approach? / We need evidence of access, buying behavior, and delivery capacity. / Show the market boundary, filters, and capture assumptions together. / A substitute may solve the same need in a different way. / Which buyers or suppliers can influence the terms? / The model does not guarantee that we will win those sales. / A bottom-up estimate can test the top-down calculation. / Are we measuring revenue, volume, accounts, or profit? / The current service area limits the relevant opportunity. / How might existing competitors respond to entry? / We have a bounded estimate, with capture still to validate.
Vocabulary: market boundary: The definition of customers, products, and geography included in an analysis. / total addressable market: Total demand within a clearly defined offering and market boundary. / serviceable available market: The portion of defined demand the business can serve with its offering and reach. / serviceable obtainable market: The portion of serviceable demand realistically targeted for capture under stated assumptions. / top-down estimate: An estimate derived by narrowing a larger aggregate. / bottom-up estimate: An estimate built from smaller units such as accounts, usage, and prices. / capture assumption: An assumed share of available demand won by the company. / market share: A company's sales or volume relative to a defined market total. / industry structure: The configuration of participants and forces shaping competition. / profit pool: The total profits available in a defined set of activities or segments. / value chain: The linked activities that create and deliver an offering. / value capture: The portion of created value retained by a participant. / buyer power: Customers' ability to influence prices or terms. / supplier power: Input providers' ability to influence prices or terms. / rivalry: Competition among existing participants. / substitute: An alternative way to meet the same underlying need. / barrier to entry: A condition making entry more difficult or costly. / switching cost: The cost or difficulty of changing providers or approaches. / concentration: The degree to which activity is held by a few participants. / price elasticity: Responsiveness of demand to price changes on a stated basis. / channel access: The ability to reach customers through relevant distribution routes. / regulatory barrier: An applicable rule or authorization requirement affecting participation. / market segmentation: Division of demand into relevant customer or usage groups. / competitive response: A rival's possible or observed reaction to a company's move.
Speaking task: Check the answers, then read the market discussion in pairs. Keep $10 billion, $400 million, and $120 million as nested boundaries. Switch roles for the capture discussion. Stress assuming ten percent and annual revenue; do not turn the implied $12 million into profit or confirmed orders. Complete and check the regional-market exchange. Read $80 million as a subset of $200 million, not an amount to add to it.
Partner: Kai: Strategy analyst / Yara: Commercial director
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 report estimates a $900 million category, including a $200 million target segment. Of that segment, $80 million is in the current region. The figures describe nested groups.
Model for comparison AFTER my attempt, not a response to give me first: Yara: Before entering, we also need to know whether distribution access, permissions, or capabilities limit participation. None of that is answered by the share calculation.
Kai: Those are possible barriers to entry. We should identify and verify the relevant ones, then reflect them in the entry options rather than leave them outside the model.
Yara: I will separate the four numbers on the slide. Keep ten percent labeled as an assumption; nobody has validated that share yet.
Kai: I will add a bottom-up estimate using potential accounts and realistic usage assumptions. That will give us a more useful test of the opportunity than repeating a large industry total.

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.

Speaking task: Check the answers, then read the market discussion in pairs. Keep $10 billion, $400 million, and $120 million as nested boundaries. Switch roles for the capture discussion. Stress assuming ten percent and annual revenue; do not turn the implied $12 million into profit or confirmed orders. Complete and check the regional-market exchange. Read $80 million as a subset of $200 million, not an amount to add to it.
Partner: Kai: Strategy analyst / Yara: Commercial director
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 report estimates a $900 million category, including a $200 million target segment. Of that segment, $80 million is in the current region. The figures describe nested groups.
Model for comparison AFTER my attempt, not a response to give me first: Yara: Before entering, we also need to know whether distribution access, permissions, or capabilities limit participation. None of that is answered by the share calculation.
Kai: Those are possible barriers to entry. We should identify and verify the relevant ones, then reflect them in the entry options rather than leave them outside the model.
Yara: I will separate the four numbers on the slide. Keep ten percent labeled as an assumption; nobody has validated that share yet.
Kai: I will add a bottom-up estimate using potential accounts and realistic usage assumptions. That will give us a more useful test of the opportunity than repeating a large industry total.

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.

Course: Corporate Strategy English
Professional audience: corporate strategy, CEO office, transformation, corporate development, strategic finance, product strategy, and internal consulting teams
Scope: Original fictional language practice, not investment, legal, accounting, valuation, or transaction advice. Figures are teaching assumptions, not forecasts. Actual strategic decisions require verified company facts, appropriate analysis, authorized governance, and qualified review where needed.
Lesson 04: Business Models, Unit Economics, Capabilities, and Advantage
Original fictional case: A new service charges $100 per completed job and incurs $115 in variable delivery costs per job. Monthly completed jobs increased from 1,000 to 1,500, with price and variable cost per job unchanged. Fixed costs, acquisition costs, and taxes are excluded from these figures. A slide calls rising revenue proof of a sound business model. Business lead Mei and finance partner Hugo must explain the negative contribution and identify what would need to change before higher volume could support profitability.
Language workshop: More orders, more negative contribution
Communication goal: Explain a growing service's economics and challenge an unsupported claim that scale alone will solve the loss.
Language guidance: The service loses $15 of contribution per job on the stated revenue and variable-cost basis. At 1,000 jobs the contribution is negative $15,000; at 1,500 it is negative $22,500. Fixed and acquisition costs are excluded, so these are not complete operating-profit figures.
Useful expressions (preserve the supplied facts): More completed jobs show higher volume, not automatically a sound model. / We are measuring one completed job. / Each $100 of job revenue carries $115 of variable delivery cost. / Contribution is negative $15 per job before the excluded costs. / More volume at unchanged unit economics increases the negative contribution. / Which specific change would improve price or variable cost? / Fixed costs, acquisition costs, and taxes are not included here. / Test the proposed economics before treating scale as the solution. / Revenue growth and profitability answer different questions. / Does the delivery figure include every relevant variable item? / This contribution figure is not complete operating profit. / We need evidence of willingness to pay before assuming a higher price. / Which capability or process change could reduce cost to serve? / Compare customers on a consistent cost and time basis. / A lower future unit cost remains an assumption until supported. / We can investigate the model without declaring it proven or impossible.
Vocabulary: business model: The logic by which a business creates, delivers, and captures value. / unit economics: Revenue and cost relationships for a defined unit of activity. / revenue model: The way an offering generates income from customers. / monetization: Converting an offering or usage into revenue. / variable cost: A cost that changes with the relevant level of activity. / fixed cost: A cost treated as unchanged within a stated activity range and period. / contribution: Revenue less the specified variable costs, before other excluded costs. / contribution margin ratio: Contribution divided by revenue on a stated basis. / gross margin: Revenue less cost of goods or services sold, expressed as an amount or ratio. / operating leverage: Sensitivity of operating profit to revenue changes given the cost structure. / break-even volume: The volume at which revenue covers the included costs under stated assumptions. / cost to serve: Costs associated with delivering and supporting an offering for a customer. / customer acquisition cost: The cost of acquiring a customer under a defined cost and customer basis. / customer lifetime value: Estimated value generated over a customer relationship under a stated model. / payback period: Time required to recover an investment or acquisition cost on a defined basis. / retention: Continued customer participation or spending under a stated measure. / churn: Customer or revenue loss over a defined period and base. / cohort economics: Revenue and costs tracked for a group with shared entry characteristics. / scalability: Ability to grow activity without proportionate deterioration in performance or economics. / economies of scale: Cost advantages associated with increased scale under relevant conditions. / learning curve: Changes in performance or cost associated with accumulated experience. / capability gap: A missing ability required to deliver the intended strategy. / defensibility: The extent to which an advantage can resist imitation or erosion. / willingness to pay: The amount customers are prepared to pay under relevant conditions.
Speaking task: Check the cloze key and read the economics exchange. Emphasize $100 price, $115 variable cost, and negative $15 contribution per job. Switch roles for the growth discussion. Contrast $50,000 additional revenue with $7,500 more negative contribution; leave excluded costs visible. Complete and check the break-even exchange. Say $30 contribution, $15,000 fixed costs, and 500 jobs, preserving the simplified assumptions.
Partner: Mei: Business lead / Hugo: Finance partner
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 simplified service charges $120 per job, has $90 variable cost per job, and $15,000 monthly fixed costs. Assume constant unit economics and no other costs for this exercise.
Model for comparison AFTER my attempt, not a response to give me first: Mei: Some customers may use the service repeatedly, while others use it once. An overall average could hide very different patterns.
Hugo: That is where cohort economics can help. We need consistent definitions and enough follow-up to compare groups, rather than calling all customers equally valuable from one month's total.
Mei: I will remove the sound-business-model claim. Show the higher demand beside the larger contribution loss, then identify which pricing and delivery assumptions need testing.
Hugo: That is a sound test of scalability. The service may have options worth exploring, but growth alone has not proved that the business model creates a sustainable positive return.

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: Portfolio Strategy, Capital Allocation, and Resource Reallocation
Original fictional case: Two divisions each request $2 million from a $3 million investment envelope. Alpha projects $700,000 annual gross savings and Beta $900,000, but implementation timing, ongoing costs, and benefit validation are incomplete. Each proposal currently assumes full funding; neither identifies the work that would stop or wait. Alpha has already spent $400,000 on a completed feasibility study that cannot be recovered. Portfolio lead Ivo and finance director Grace must frame the allocation decision without treating gross savings as net value or past spending as automatic justification.
Language workshop: A budget choice with no stop-doing consequences
Communication goal: Compare competing investment requests on a consistent basis and expose displaced work and sunk-cost reasoning.
Language guidance: The full requests total $4 million, so they cannot both fit a $3 million envelope unchanged. A $1.5 million allocation to each is not automatically a feasible compromise because both current scopes assume $2 million. Reduced funding needs a revised delivery and benefit case.
Useful expressions (preserve the supplied facts): Full funding for both requests exceeds the envelope by $1 million. / Are the benefits measured over the same period and cost basis? / These are projected gross savings, not validated net cash flows. / What work would stop, shrink, or wait if this proposal is funded? / The feasibility study is unrecoverable past spending. / We should use the study's evidence without treating its cost as a reason to continue. / A smaller allocation needs a revised scope and benefit case. / Compare forward costs, benefits, risks, timing, and displaced alternatives. / Who is accountable for realizing each saving? / Do both proposals claim the same benefit? / When would the cash costs and benefits actually occur? / Further funding should depend on the stated evidence and review. / The larger gross-saving figure does not settle the allocation. / Show the best competing use of the limited funds. / Which future costs remain avoidable, and which are already committed? / A return estimate is only as reliable as its assumptions and scope.
Vocabulary: portfolio strategy: The approach to managing a set of businesses or investments together. / capital allocation: Distribution of financial resources among competing uses. / investment envelope: The total authorized resources available for a set of investments. / capital rationing: Selection among investments when available funding is limited. / resource reallocation: Moving resources from one use to another. / investment case: The rationale, economics, risks, and implementation plan for a proposed investment. / incremental cash flow: Cash flow that changes because an option is chosen. / sunk cost: An incurred cost that cannot be recovered or changed by the current decision. / avoidable cost: A cost that can be prevented by choosing a particular course of action. / committed cost: A cost arising from an existing commitment that may not be easily changed. / benefit realization: Actual achievement and verification of intended benefits. / gross benefit: A benefit before the relevant offsetting costs are deducted. / net benefit: Benefits less the included costs under a specified basis. / net present value: Discounted future net cash flows less the relevant initial investment. / internal rate of return: A discount rate at which the modeled net present value is zero. / hurdle rate: A required return threshold used to evaluate an investment. / weighted average cost of capital: A weighted measure of the required returns on a company's financing sources. / return on invested capital: Operating return relative to invested capital on a defined accounting basis. / capital intensity: The amount of capital required relative to output, sales, or another stated base. / divestment: Disposal of a business, investment, or asset. / harvest strategy: A strategy emphasizing cash extraction with limited further investment. / stage-gated funding: Funding released in stages after specified reviews. / benefit owner: The person accountable for delivering and verifying a benefit. / dependency map: A record of relationships that affect delivery or benefits across initiatives.
Speaking task: Check the answers and read the allocation discussion. Keep the $4 million total request and $3 million funding envelope distinct. Switch roles for the study discussion. Stress unrecoverable past cost while retaining useful evidence; neither gross savings figure settles the ranking. Complete and check the study-to-pilot exchange. Read $30,000 as sunk and $70,000 as proposed new spending that still needs approval.
Partner: Ivo: Portfolio lead / Grace: Finance director
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 completed, nonrefundable study cost $30,000. A new pilot would require another $70,000. The study contains useful evidence, but no pilot approval has been given.
Model for comparison AFTER my attempt, not a response to give me first: Ivo: If the initial evidence is promising but incomplete, we could fund a defined stage and review the result before releasing the rest.
Grace: That is stage-gated funding, provided the gate has real criteria and authority. It should not become a full commitment disguised as a sequence of automatic approvals.
Ivo: I will ask both sponsors for feasible versions within the envelope. Use what Alpha's study taught us, but do not count its unrecoverable cost as a reason to proceed.
Grace: Good. The final capital allocation should explain why the chosen use of funds is preferable on that shared basis. A larger gross number or a completed study cannot substitute for the decision logic.

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.

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.

Professional audience: corporate strategy, CEO office, transformation, corporate development, strategic finance, product strategy, and internal consulting teams
Scope: Original fictional language practice, not investment, legal, accounting, valuation, or transaction advice. Figures are teaching assumptions, not forecasts. Actual strategic decisions require verified company facts, appropriate analysis, authorized governance, and qualified review where needed.
Lesson 05: Portfolio Strategy, Capital Allocation, and Resource Reallocation
Original fictional case: Two divisions each request $2 million from a $3 million investment envelope. Alpha projects $700,000 annual gross savings and Beta $900,000, but implementation timing, ongoing costs, and benefit validation are incomplete. Each proposal currently assumes full funding; neither identifies the work that would stop or wait. Alpha has already spent $400,000 on a completed feasibility study that cannot be recovered. Portfolio lead Ivo and finance director Grace must frame the allocation decision without treating gross savings as net value or past spending as automatic justification.
Language workshop: A budget choice with no stop-doing consequences
Communication goal: Compare competing investment requests on a consistent basis and expose displaced work and sunk-cost reasoning.
Language guidance: The full requests total $4 million, so they cannot both fit a $3 million envelope unchanged. A $1.5 million allocation to each is not automatically a feasible compromise because both current scopes assume $2 million. Reduced funding needs a revised delivery and benefit case.
Useful expressions (preserve the supplied facts): Full funding for both requests exceeds the envelope by $1 million. / Are the benefits measured over the same period and cost basis? / These are projected gross savings, not validated net cash flows. / What work would stop, shrink, or wait if this proposal is funded? / The feasibility study is unrecoverable past spending. / We should use the study's evidence without treating its cost as a reason to continue. / A smaller allocation needs a revised scope and benefit case. / Compare forward costs, benefits, risks, timing, and displaced alternatives. / Who is accountable for realizing each saving? / Do both proposals claim the same benefit? / When would the cash costs and benefits actually occur? / Further funding should depend on the stated evidence and review. / The larger gross-saving figure does not settle the allocation. / Show the best competing use of the limited funds. / Which future costs remain avoidable, and which are already committed? / A return estimate is only as reliable as its assumptions and scope.
Vocabulary: portfolio strategy: The approach to managing a set of businesses or investments together. / capital allocation: Distribution of financial resources among competing uses. / investment envelope: The total authorized resources available for a set of investments. / capital rationing: Selection among investments when available funding is limited. / resource reallocation: Moving resources from one use to another. / investment case: The rationale, economics, risks, and implementation plan for a proposed investment. / incremental cash flow: Cash flow that changes because an option is chosen. / sunk cost: An incurred cost that cannot be recovered or changed by the current decision. / avoidable cost: A cost that can be prevented by choosing a particular course of action. / committed cost: A cost arising from an existing commitment that may not be easily changed. / benefit realization: Actual achievement and verification of intended benefits. / gross benefit: A benefit before the relevant offsetting costs are deducted. / net benefit: Benefits less the included costs under a specified basis. / net present value: Discounted future net cash flows less the relevant initial investment. / internal rate of return: A discount rate at which the modeled net present value is zero. / hurdle rate: A required return threshold used to evaluate an investment. / weighted average cost of capital: A weighted measure of the required returns on a company's financing sources. / return on invested capital: Operating return relative to invested capital on a defined accounting basis. / capital intensity: The amount of capital required relative to output, sales, or another stated base. / divestment: Disposal of a business, investment, or asset. / harvest strategy: A strategy emphasizing cash extraction with limited further investment. / stage-gated funding: Funding released in stages after specified reviews. / benefit owner: The person accountable for delivering and verifying a benefit. / dependency map: A record of relationships that affect delivery or benefits across initiatives.

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: Growth Strategy, Market Entry, Partnerships, and M&A Logic
Original fictional case: A proposed acquisition case claims $4 million in annual procurement savings once fully implemented. The estimate assumes combined buying volumes and revised supplier contracts. No supplier has confirmed the proposed terms, and no integration plan or cost-to-achieve estimate exists. The purchase price is outside this meeting. Strategy lead Elena and integration director Marcus must identify the evidence needed before presenting the savings as dependable. The executive committee has authorized analysis only, not a bid. Building internally and forming a partnership remain alternatives.
Language workshop: A savings headline without an integration plan
Communication goal: Qualify an acquisition rationale and distinguish recurring potential from timed, net cash benefits.
Language guidance: Annual run-rate savings are not automatically cash received during the first year. A change introduced halfway through a year has a different time profile from one operating throughout it. The proposal also needs implementation costs and offsetting effects before anyone labels the benefit net.
Useful expressions (preserve the supplied facts): The $4 million is an unverified annual run-rate estimate. / When would each saving begin, and when would it reach full effect? / That is not yet a first-year cash-flow forecast. / We need the cost to achieve before describing a net benefit. / Which supplier terms must change for the savings to occur? / We should compare building, buying, and partnering on the same basis. / The committee authorized analysis, not a bid. / Who is accountable for validating and delivering this saving? / What would improve in the standalone business anyway? / Let us remove benefits already counted in the existing improvement plan. / This saving depends on successful supplier renegotiation. / Could integration disrupt the customers we need to retain? / Strategic fit supports the rationale but does not establish the price. / Show the steps from gross potential to timed net cash flows. / A positive diligence finding does not itself confer transaction authority. / Return with verified assumptions, delivery costs, timing, and accountable owners.
Vocabulary: acquisition rationale: The explanation of why buying a business may create value. / strategic fit: The relationship between an option and the company's objectives and capabilities. / build-buy-partner: A comparison of internal development, acquisition, and collaboration routes. / organic growth: Expansion generated within the business rather than by acquisition. / inorganic growth: Expansion through acquisitions or similar external combinations. / market-entry mode: The arrangement used to enter a market. / partnership model: The agreed structure for collaborating with another organization. / deal thesis: The central value-creation argument for a transaction. / synergy: An additional benefit expected from combining activities or businesses. / run-rate savings: The recurring savings level expected once changes are fully operating. / gross savings: Savings before specified implementation or offsetting costs. / cost to achieve: Spending required to deliver a proposed benefit. / integration roadmap: A sequenced plan for combining selected activities. / integration dependency: A prerequisite affecting the delivery of combined operations. / commercial diligence: Investigation of market and customer assumptions behind a proposal. / supplier renegotiation: Discussion intended to change existing supplier terms. / revenue dissynergy: Lost revenue associated with the disruption or combination. / customer retention: The maintenance of existing customer relationships or revenue. / standalone case: Expected performance without the proposed combination. / incremental value: Additional value relative to the chosen comparison case. / double-counting: Including the same underlying benefit or cost more than once. / execution risk: The possibility that implementation does not deliver the plan. / bid authority: Permission to submit an offer within specified limits. / integration owner: The person accountable for a defined integration activity.
Speaking task: After checking the cloze answers, read the acquisition exchange. Keep the $4 million as potential annual run-rate savings, not confirmed first-year cash. Switch roles for turns 11-20. Distinguish customer exposure, integration ownership, and bid authority; no offer is authorized. Complete the July-start exchange and check its key. Read $60,000 six-month savings less $40,000 implementation payment as $20,000 net on the stated basis.
Partner: Elena: Strategy lead / Marcus: Integration director
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 fictional saving of $120,000 per year begins on July 1 and accrues evenly. A one-time implementation payment is $40,000. Ignore taxes, discounting, and other costs; use six months of savings.
Model for comparison AFTER my attempt, not a response to give me first: Elena: One colleague thinks a stronger savings slide means we can submit an offer. The committee only authorized analysis.
Marcus: Then the pack must say no bid authority has been granted. Better evidence supports a later request; it does not extend our authority.
Elena: Keep the four million labeled potential, show the missing evidence, and bring the alternative routes back. We are not deciding a purchase price today.
Marcus: I will keep the deal thesis provisional and assign the validation work. The next paper will distinguish recurring potential, timed cash, and the decision actually requested.

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.

REFERENCE
Course: Corporate Strategy English
Professional audience: corporate strategy, CEO office, transformation, corporate development, strategic finance, product strategy, and internal consulting teams
Scope: Original fictional language practice, not investment, legal, accounting, valuation, or transaction advice. Figures are teaching assumptions, not forecasts. Actual strategic decisions require verified company facts, appropriate analysis, authorized governance, and qualified review where needed.
Lesson 06: Growth Strategy, Market Entry, Partnerships, and M&A Logic
Original fictional case: A proposed acquisition case claims $4 million in annual procurement savings once fully implemented. The estimate assumes combined buying volumes and revised supplier contracts. No supplier has confirmed the proposed terms, and no integration plan or cost-to-achieve estimate exists. The purchase price is outside this meeting. Strategy lead Elena and integration director Marcus must identify the evidence needed before presenting the savings as dependable. The executive committee has authorized analysis only, not a bid. Building internally and forming a partnership remain alternatives.
Language workshop: A savings headline without an integration plan
Communication goal: Qualify an acquisition rationale and distinguish recurring potential from timed, net cash benefits.
Language guidance: Annual run-rate savings are not automatically cash received during the first year. A change introduced halfway through a year has a different time profile from one operating throughout it. The proposal also needs implementation costs and offsetting effects before anyone labels the benefit net.
Useful expressions (preserve the supplied facts): The $4 million is an unverified annual run-rate estimate. / When would each saving begin, and when would it reach full effect? / That is not yet a first-year cash-flow forecast. / We need the cost to achieve before describing a net benefit. / Which supplier terms must change for the savings to occur? / We should compare building, buying, and partnering on the same basis. / The committee authorized analysis, not a bid. / Who is accountable for validating and delivering this saving? / What would improve in the standalone business anyway? / Let us remove benefits already counted in the existing improvement plan. / This saving depends on successful supplier renegotiation. / Could integration disrupt the customers we need to retain? / Strategic fit supports the rationale but does not establish the price. / Show the steps from gross potential to timed net cash flows. / A positive diligence finding does not itself confer transaction authority. / Return with verified assumptions, delivery costs, timing, and accountable owners.
Vocabulary: acquisition rationale: The explanation of why buying a business may create value. / strategic fit: The relationship between an option and the company's objectives and capabilities. / build-buy-partner: A comparison of internal development, acquisition, and collaboration routes. / organic growth: Expansion generated within the business rather than by acquisition. / inorganic growth: Expansion through acquisitions or similar external combinations. / market-entry mode: The arrangement used to enter a market. / partnership model: The agreed structure for collaborating with another organization. / deal thesis: The central value-creation argument for a transaction. / synergy: An additional benefit expected from combining activities or businesses. / run-rate savings: The recurring savings level expected once changes are fully operating. / gross savings: Savings before specified implementation or offsetting costs. / cost to achieve: Spending required to deliver a proposed benefit. / integration roadmap: A sequenced plan for combining selected activities. / integration dependency: A prerequisite affecting the delivery of combined operations. / commercial diligence: Investigation of market and customer assumptions behind a proposal. / supplier renegotiation: Discussion intended to change existing supplier terms. / revenue dissynergy: Lost revenue associated with the disruption or combination. / customer retention: The maintenance of existing customer relationships or revenue. / standalone case: Expected performance without the proposed combination. / incremental value: Additional value relative to the chosen comparison case. / double-counting: Including the same underlying benefit or cost more than once. / execution risk: The possibility that implementation does not deliver the plan. / bid authority: Permission to submit an offer within specified limits. / integration owner: The person accountable for a defined integration activity.
Speaking task: After checking the cloze answers, read the acquisition exchange. Keep the $4 million as potential annual run-rate savings, not confirmed first-year cash. Switch roles for turns 11-20. Distinguish customer exposure, integration ownership, and bid authority; no offer is authorized. Complete the July-start exchange and check its key. Read $60,000 six-month savings less $40,000 implementation payment as $20,000 net on the stated basis.
Partner: Elena: Strategy lead / Marcus: Integration director
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 fictional saving of $120,000 per year begins on July 1 and accrues evenly. A one-time implementation payment is $40,000. Ignore taxes, discounting, and other costs; use six months of savings.
Model for comparison AFTER my attempt, not a response to give me first: Elena: One colleague thinks a stronger savings slide means we can submit an offer. The committee only authorized analysis.
Marcus: Then the pack must say no bid authority has been granted. Better evidence supports a later request; it does not extend our authority.
Elena: Keep the four million labeled potential, show the missing evidence, and bring the alternative routes back. We are not deciding a purchase price today.
Marcus: I will keep the deal thesis provisional and assign the validation work. The next paper will distinguish recurring potential, timed cash, and the decision actually requested.

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.

Actual strategic decisions require verified company facts, appropriate analysis, authorized governance, and qualified review where needed.
Lesson 07: Uncertainty, Scenarios, Strategic Options, and Risk Posture
Original fictional case: A planning team models next year using two illustrative cases. The base case assumes 10,000 units at $200 each. A downside case assumes 8,000 units at $180 each. No probabilities have been assigned, and neither case is an approved forecast. A proposed expansion can begin with a reversible $50,000 test or proceed to a $500,000 commitment. Neither route is approved. Strategist Noor and operations lead Leo must distinguish scenarios from predictions and propose measurable review triggers without implying that uncertainty has disappeared.
Language workshop: A plausible downside is not a prediction
Communication goal: Describe conditional outcomes and connect observable signposts to proportionate, authorized responses.
Language guidance: A base case is not automatically the most likely outcome, and two scenarios do not automatically have a 50% probability each. If no probabilities have been established, report the cases without inventing them. Plausibility describes what could happen; probability makes a different, quantified claim.
Useful expressions (preserve the supplied facts): If volume and price follow these assumptions, revenue would be $1.44 million. / These are planning scenarios, not approved forecasts. / We have not assigned probabilities to either case. / The base case is our comparison point, not a guarantee. / Which option remains workable across both scenarios? / The smaller test preserves a later decision on full expansion. / Which observable signposts would challenge the current assumption? / Let us agree the measure, threshold, and review period. / Meeting the threshold triggers a review, not automatic spending. / Show how the result changes when price and volume move separately. / This case tests adverse conditions without predicting that they will occur. / Reversibility reduces some commitment risk; it does not guarantee success. / The pilot evidence must be reviewed before any larger commitment. / What action would the decision owner consider if the trigger is met? / How much can we commit before the next evidence review? / The decision depends on assumptions that remain open to revision.
Vocabulary: scenario: A coherent description of a possible future under stated assumptions. / base case: A reference set of assumptions used for comparison. / downside case: A set of assumptions producing a less favorable outcome. / forecast: An estimate of expected future results using a stated method. / prediction: A statement about what is expected to happen. / probability: A quantified expression of likelihood on a stated basis. / plausibility: The degree to which an outcome is reasonably conceivable. / uncertainty: Lack of sufficient knowledge about outcomes or relevant conditions. / sensitivity analysis: Examination of how changing inputs affects a result. / stress test: Analysis of performance under specified adverse conditions. / signpost: An observable development relevant to an uncertain future. / leading indicator: A measure that may provide an early signal of later performance. / lagging indicator: A measure reflecting results after relevant activity has occurred. / trigger: A defined condition prompting a specified review or response. / threshold: The level at which a stated condition is met. / contingency plan: A prepared response to a specified possible development. / reversible decision: A choice that can be changed with limited exit consequences. / irreversible commitment: A commitment difficult or costly to undo. / option value: The value of preserving a future choice under uncertainty. / staged commitment: An allocation made in steps subject to specified reviews. / risk appetite: The types and amount of risk an organization is willing to pursue or retain. / risk tolerance: The acceptable variation or limits around a defined exposure or objective. / robust option: A choice that performs acceptably across the scenarios examined. / decision gate: A defined review point before a further commitment.
Speaking task: Check the answers and read the scenario exchange. Use would for the $2 million and $1.44 million conditional revenue results. Switch roles for the staged-decision discussion. Keep $50,000 and $500,000 as unapproved options, and do not assign probabilities to the cases. Complete and check the three-week trigger exchange. Stress 76, 79, and 78 below 80 for three consecutive weeks; the response is review, not cancellation.
Partner: Noor: Strategist / Leo: Operations 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: The agreed rule calls for a review if confirmed weekly orders remain below 80 for three consecutive weeks. The last three totals are 76, 79, and 78. The rule grants no automatic cancellation authority.
Model for comparison AFTER my attempt, not a response to give me first: Leo: The sponsor must define acceptable exposure before that review. Otherwise the team could keep spending while describing every step as learning.
Noor: Document the risk limits and decision authority. A staged approach needs an actual boundary; calling something a pilot does not make an open-ended commitment small or reversible.
Leo: I will request the fifty-thousand-dollar test with explicit limits. Keep the five-hundred-thousand-dollar expansion outside that request so the two approvals cannot be confused.
Noor: Add the next decision gate and the evidence required there. That gives the committee a practical way to act under uncertainty without pretending that we know the future.

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.
