MBA Case Discussion English Practice: Speak With Evidence

MBA case discussion English should make your reasoning visible: identify the decision, take a position, use case evidence, address a trade-off, and respond to challenge. Advanced vocabulary cannot rescue a contribution that never reaches a decision.

Harvard Business School describes case learning as analysing incomplete information, choosing a course of action, discussing diverse perspectives, engaging in class, and reflecting afterward. Your programme's case method, participation grade, and AI policy remain authoritative.

Key takeaways

• Prepare the decision and recommendation before polishing language.
• Use case facts as evidence, not a plot summary.
• Enter with one contribution that advances the current thread.
• Disagree with an assumption, criterion, or conclusion, not a person.
• Paraphrase missing vocabulary and continue the reasoning.
• Reflect on one analytical and one communication improvement after class.

Case discussion map

The case may have several valid positions. Your task is to make one defensible under the available information.

Prepare the case

Create a one-page decision sheet:

1. Protagonist or decision-maker.
2. Decision and deadline.
3. Objective and criteria.
4. Three material facts.
5. Two or three alternatives.
6. Recommendation.
7. Main risk or assumption.
8. Implementation first step.
9. One opposing argument.
10. Three business terms you need to pronounce.

Avoid retelling the full chronology. Ask which facts change the choice.

Prepare a thirty-second position:

"The decision is whether the fictional company should enter market B this year. I recommend delaying entry for six months because distribution capacity is unverified and the current cash buffer cannot absorb the downside scenario. The opportunity is attractive, but the sequence should be pilot, validate, then scale."

Give a cold-call opening

Use Decision, Recommendation, Evidence, Trade-off:

"The decision is whether to launch nationally or pilot first. I recommend a regional pilot because the case shows strong demand but weak fulfilment capacity. A national launch captures more growth, but it risks service failure before the company knows its operating limit."

If you need a moment:

• "I would frame the decision as..."
• "My initial recommendation is..."
• "The strongest evidence is..."
• "The main trade-off is..."

Do not begin with "This case is about a company that..." unless the instructor asked for summary.

Enter the live discussion

Listen for the current thread and choose a function:

Add evidence

"I would add one figure to that argument: the regional margin falls below the target after distribution cost."

Connect

"This connects to Mina's capacity point because the marketing plan assumes fulfilment can double immediately."

Challenge

"I agree demand exists, but the recommendation depends on an untested conversion assumption."

Reframe

"We are debating channel choice, but the prior decision may be whether the company should enter at all."

Ask

"Which criterion should dominate if growth and cash protection conflict?"

Use university seminar phrases for broader turn-taking practice.

Use evidence and numbers

State Fact, Interpretation, Decision relevance:

"Customer acquisition cost rose 30 percent in the second region. That suggests the first market's economics may not generalise, so I would not use its payback period for national expansion."

For assumptions:

"The forecast assumes the same retention rate after price increases. If retention falls, option A loses its advantage."

For incomplete information:

"The case does not provide competitor response data. I would treat that as a decision risk rather than assume no response."

Read important numbers slowly and connect them to meaning. Correct a wrong figure immediately.

Disagree and build

Use Point, Common ground, Difference, Evidence, Alternative:

"I agree that market growth supports expansion. I disagree on timing because the distribution assumption is not tested. A six-month regional pilot preserves the opportunity while producing operating evidence."

Useful phrases:

• "I read the same evidence differently."
• "That conclusion holds only if..."
• "The alternative criterion is..."
• "What evidence would change your recommendation?"
• "Could both positions be true at different time horizons?"

Use polite disagreement English for more pressure drills.

Handle uncertainty and missing words

Missing term

"I cannot recall the term, but I mean the cash required for daily operations."

Incomplete evidence

"The case does not resolve that point. My recommendation assumes..."

Changed mind

"The capacity evidence changes my view. I would now support the pilot rather than national launch."

Missed question

"I understood the question about timing but missed the comparison. Could you repeat that part?"

Changing a position after better evidence demonstrates reasoning, not failure.

Reflect after class

Use four prompts:

1. Which contribution changed my analysis?
2. Which evidence did I miss?
3. Which contribution of mine advanced or repeated the discussion?
4. What one language function should I practise before the next case?

Do not judge performance only by how many times you spoke. Listening, evidence quality, timing, and ability to build on others matter.

Fictional case role-play

Decision: A fictional education company must choose national launch, regional pilot, or delay.

Facts: Demand is strong, distribution capacity is uncertain, cash covers nine months, and one region has lower margins.

Roles: CEO prioritises growth, CFO prioritises cash, operations leader prioritises service quality, and student recommends a course of action.

Unexpected questions:

• "What evidence would make you launch nationally?"
• "Why is six months the right pilot length?"
• "What is the cost of waiting?"
• "Which assumption is most dangerous?"
• "What would you do in the first thirty days?"

Use only fictional data in public tools.

What real MBA students commonly find difficult

Recurring difficulties include summarising instead of deciding, waiting for a perfectly original point, and losing the contribution while translating. A prepared position plus flexible functions makes participation faster without turning it into recitation.

Students also report equating confidence with certainty. Case discussion often rewards explicit assumptions and willingness to revise when new evidence appears.

Where SpeakShark fits

SpeakShark can role-play fictional classmates or stakeholders who challenge a recommendation. It cannot analyse licensed case content safely by default or determine a participation grade.

Use international-student speaking practice, speaking-anxiety practice, and office-hours English for supporting skills.

How we researched this guide

We used Harvard Business School's current Case Method and learning-model pages, Harvard Kennedy School case-learning guidance, and Cornell's introductory case-method note. We created a fictional case rather than reproducing licensed case content. Course participation and AI policies remain authoritative.

FAQ

Prepare decision, objective, constraints, evidence, alternatives, recommendation, risk, one opposing argument, and a short opening position rather than a speech.

State the decision and recommendation first, support with one or two facts, acknowledge the main trade-off, and stop for follow-up.

Name the disputed assumption or conclusion, acknowledge shared ground, use case evidence, and offer an alternative that advances the analysis.

Paraphrase the function and continue the reasoning. Prepare case-specific vocabulary but do not abandon a useful contribution while searching for one word.

Make one claim, support it, connect it to the decision, and leave space for others. Follow the instructor's actual expectations.

Follow course policy. Do not disclose protected content, replace your analysis, or present generated participation as your own work.
