1. Introduction
Most students prepare for group discussions by collecting opinions on current affairs. A case study group discussion asks for something different. You are given a situation with facts, constraints and people, and your group must work out what should be done and why. Fluency helps. Structure wins.
This guide teaches a structure: the PREPON Six-Step Case Study Discussion Framework. It introduces six planned companion resources, each designed to contain a fully solved fictional case, a complete simulated discussion and individual candidate evaluations. This pillar explains the ten-dimension feedback rubric and provides nine further practice cases to try yourself.
A few honest limits. The cases, transcripts and scores are fictional PREPON instructional material; they are not real assessment questions or real candidates. The rubric is a PREPON training tool, not an official scoring system used by any institution. Timelines are suggestions, not guarantees.
If you want the broad overview of group-assessment formats first, read PREPON’s guide to Group Discussion for MBA Admissions; this article goes deeper into case analysis, decision-making and feedback.
What Is a Case Study Group Discussion?
In a case study group discussion, participants must develop a reasoned recommendation from a shared scenario; they are not simply exchanging opinions about a broad topic.
A case study discussion is a group exercise in which participants read or hear a business, organisational, social or ethical scenario and discuss what the decision-maker should do. Typically the group is expected to analyse the situation, weigh alternatives and arrive at a recommendation, or explain clearly where it disagrees.
It differs from an opinion-based group discussion in three ways:
• The facts are supplied. You are judged less on how much you know and more on how well you use what is given.
• There is a decision to make. Discussion that never lands on a recommendation is incomplete.
• Assumptions are visible. Good participants say what the case does not tell them and treat their guesses as guesses.
3. Where Case Study Discussions Are Used
The format of a case study group discussion depends on the institution or employer, so candidates should check the stated selection process instead of assuming every assessment uses the same exercise.
MBA admissions. Some programmes may use case-based discussions or group exercises in selection. Formats vary by institution and by year, and many do not use them. For example, the IIM Ahmedabad PGP 2026–28 official shortlisting document identifies an Analytical Writing Test and a Personal Interview as selection stages; it does not describe a Case Study GD as a current requirement (source).
SPJIMR uses the term Group Interview in its admissions information (source); do not assume it works like a conventional case discussion. For any institution you are targeting, rely on its current official admission notice.
Campus placements. Some recruiters use assessment-centre group exercises or case-based discussions to observe collaborative problem-solving, commercial awareness, stakeholder thinking and constructive leadership. Many recruiters do not. Check the process described by each recruiter. For aptitude-test preparation, see PREPON’s Placement Aptitude Test Preparation.
Job interviews. Some employers run group case discussions; many use individual case interviews, competency interviews or role-based exercises instead.
4. Case Study Discussion vs Other Formats
A case study group discussion differs from an individual case interview because peers must analyse the scenario together while assessors may observe both reasoning and group behaviour.
| Format | What happens | Main focus | Key difference from a case discussion |
|---|---|---|---|
| Case study discussion | Peers discuss a supplied scenario and aim at a decision | Structured analysis, decision, teamwork | — |
| Traditional GD | Peers discuss a topic or statement | Ideas, awareness, communication | No supplied facts; often no decision required |
| Group exercise | Peers complete a task (build, rank, plan, role-play) | Behaviour in action | Task output may be physical or ranked, not argued |
| Group interview | Assessors question a group | Individual answers in a group setting | Assessor-led |
| Written Ability Test | Individual writing | Written reasoning | No live interaction |
| Personal interview | Assessor and candidate | Background, motivation, judgement | One-to-one |
| Individual case interview | Interviewer guides a candidate through a case | Structured thinking, quantitative reasoning | Interviewer-led; no peers |
5. Types of Case Studies
No single industry defines a case study group discussion: business, ethics, workplace conflict and social-impact situations can all be used to test structured judgement.
| # | Category | Typical question | Dominant lens | Common trap |
|---|---|---|---|---|
| 1 | Business strategy | Enter, exit, or reposition? | Competitive position, resources | Chasing growth without capability |
| 2 | Marketing | How to reposition or launch? | Customer segments, brand | Ignoring brand dilution |
| 3 | Finance and resource allocation | Where to invest limited funds? | Return, liquidity, risk | Spending without staging |
| 4 | Operations and supply chains | How to fix delays or capacity? | Throughput, constraints | Assuming spare capacity |
| 5 | Human resources | Hire, retain, restructure? | Fairness, capability | Treating people as costs only |
| 6 | Interpersonal workplace conflicts | How to handle a dispute? | Process, fairness | Taking sides too early |
| 7 | Organisational leadership | How should a leader act? | Authority, influence | Assuming unlimited power |
| 8 | Corporate governance | Who should be told, and what is disclosed? | Accountability, compliance | Hiding inconvenient facts |
| 9 | Ethical dilemmas | Right action under pressure? | Rights, harm, duty | Rationalising the profitable choice |
| 10 | Social and public policy | Which policy trade-off? | Equity, feasibility | Ignoring affected groups |
| 11 | Service failures | How to recover customers? | Service recovery, root cause | Apologising without fixing |
| 12 | Crisis management | Act now with incomplete data? | Containment, communication | Waiting for certainty |
| 13 | Technology and digital transformation | Adopt, delay, replace? | Adoption, risk | Ignoring people impact |
| 14 | Sustainability | Cost versus environmental duty | Long-term value, compliance | Treating it as PR |
| 15 | Entrepreneurship | Pivot, scale, raise funds? | Runway, validation | Scaling before testing |
| 16 | Decision-making under uncertainty | Decide with unknowns | Scenarios, reversibility | Pretending to certainty |
The six-step framework applies to every row. Only the emphasis changes: ethical dilemmas lean on Steps 3 and 6; operations cases lean on Steps 1 and 5; leadership and governance cases lean on Step 4.
6. The PREPON Six-Step Case Study Discussion Framework
The PREPON Six-Step Decision Flow
- 1.Identify the primary decision problem
- 2.Separate associated, considered and resultant problems
- 3.List directly and indirectly affected stakeholders
- 4.Identify the decision-maker and approval authority
- 5.Evaluate credible alternatives and trade-offs
- 6.Recommend an ethical, feasible win-win option
For every case study group discussion, PREPON recommends moving from the decision problem to related problems, stakeholders, authority, alternatives and a defensible recommendation.
The framework is a PREPON instructional method. It is not an academic standard and no researcher cited later designed or endorsed it. The classifications in Step 2 are PREPON teaching categories, not universal terminology.
Step 1 — Identify the Primary Problem to Be Solved
From Symptoms to a Decision Statement
- 1.Observe the reported symptoms
- 2.Separate verified facts from assumptions
- 3.List possible causes without treating them as proven
- 4.State the decision to be made
- 5.Check that the decision is within the case scope
The first task in a case study group discussion is to state the decision that actually needs to be made, without mistaking visible symptoms for proven causes.
Ask three different questions:
• What decision must be made? (the decision problem)
• What is going wrong? (the observable symptoms)
• Why might it be happening? (possible root causes)
These are not always the same. A business may have to decide urgently before any cause is proven.
| Situation | Decision problem | Symptom | Possible causes |
|---|---|---|---|
| A café’s sales fall 20% | How to respond this month with limited cash | Footfall and revenue down | New competitor, construction outside, quality decline, seasonality |
| A hospital sees longer waits | How to restore safe waiting times this week | Patients waiting 3+ hours | Staff shortage, triage design, bed blocking, a software outage |
| A student group misses interim targets | What should the group do before Friday | Missed milestones, tension | Unclear roles, one member’s absence, scope too large |
Separate immediate problems (must be handled now) from underlying problems (must be fixed to prevent recurrence). Separate facts from assumptions, urgent from important, and what is within the decision-maker’s control from what is not.
Supporting techniques. The Five Whys and root-cause analysis help generate hypotheses about causes. They support Step 1; they do not replace the decision question. Five Whys can mislead if you stop at the first plausible answer or follow one causal chain only.
Step 2 — Identify Associated, Considered and Resultant Problems
Map the Three Types of Related Problems
- 1.Primary decision problem
- 2.Associated problems: issues occurring alongside it
- 3.Considered problems: constraints and factors to weigh
- 4.Resultant problems: foreseeable consequences
- 5.Return to the decision with a fuller risk picture
In a case study group discussion, associated issues, constraints to consider and resultant effects must be distinguished so the final recommendation does not overlook second-order harm.
| Type | Meaning | Example |
|---|---|---|
| Associated problems | Parallel or interconnected problems that accompany or contribute to the primary problem | Production delays, plus employee dissatisfaction, plus strained supplier relationships |
| Considered problems | Constraints, competing obligations and risks that must be weighed when choosing a solution | A turnaround must consider limited liquidity, safety requirements, contractual penalties and a shortage of skilled staff |
| Resultant problems | Actual or potential consequences of the existing problem or of a proposed alternative | A poorly planned workforce reduction may cause skill shortages, disputes and reputational damage |
Considered problems are not just budget: include law, safety, time, capability, contracts, ethics and reputation.
Within resultant problems, separate three timings: already occurring consequences; likely if no action is taken; and may arise from a particular solution.
Three worked mini-examples
Mini-example 1 — A late software release. Primary: the launch is two weeks late. Associated: the testing team is demoralised; the sales team has made promises to clients. Considered: a fixed vendor contract, limited testers, a security audit that cannot be skipped. Resultant (already occurring): a client has paused payment. Resultant (if no action): further client loss. Resultant (from a proposed shortcut): skipping security testing could cause a data breach.
Mini-example 2 — A restaurant with falling reviews. Primary: ratings dropped from 4.4 to 3.9. Associated: staff turnover is high. Considered: the lease and fixed costs limit price cuts; food safety standards are non-negotiable. Resultant (already occurring): fewer bookings. Resultant (from a proposal to hire cheaper chefs): further quality decline.
Mini-example 3 — Classification depends on causality. Staff turnover can be associated (a parallel problem), a cause (feeding the primary problem) or resultant (a consequence of overwork). The label depends on what the case evidence shows.
Say so in the discussion: “I’m treating turnover as associated for now, but if the data shows it started before the delays, it may be a cause.” Also note that categories can overlap: a signed penalty clause is a considered problem for solution choice and becomes a resultant problem once the penalty is triggered.
Step 3 — Identify All Stakeholders
Stakeholder Mapping Flow
- 1.Identify the directly affected people
- 2.Add indirectly affected groups
- 3.Record each group’s interests and potential harms
- 4.Assess influence, vulnerability and conflicts
- 5.Test every option against the stakeholder map
A case study group discussion becomes more rigorous when participants consider people who are affected indirectly, not just the visible customers, managers or employees.
Classify each stakeholder as direct or indirect, internal or external, vulnerable or not, decision-maker or implementer. Then ask: what do they want, what rights or obligations apply, what short- and long-term impact will they face, and where do interests conflict?
Power–interest check. High power and high interest: manage closely. High power, low interest: keep informed. Low power, high interest: protect and consult; this is where vulnerable people often sit. Low power, low interest: monitor.
Easy-to-overlook stakeholders: regulators; frontline implementers; families of affected workers; customer-support teams; suppliers’ employees; future customers; the community; the environment; competitors reacting; auditors; and the people who will maintain the solution after it is launched.
Stakeholder analysis matrix (template)
| Stakeholder | Type | Interest / incentive | Rights / obligations | Impact (short / long) | Power | Likely position |
|---|---|---|---|---|---|---|
Step 4 — Identify the Primary Decision-Maker
Authority and Implementation Flow
- 1.Who owns the decision?
- 2.Who must approve or be consulted?
- 3.Who is responsible for implementation?
- 4.What legal, ethical or operational limits apply?
- 5.Recommend actions within actual authority
Before offering a solution in a case study group discussion, ask who is permitted to decide, who must approve the change and who can actually implement it.
Ask: Who has formal authority? Who has practical control of the resources? Who is accountable? Is authority delegated? What approvals are needed? What legal restrictions apply? Are there multiple decision-makers? What must be escalated?
Distinguish the recommender from the approver. A recommendation to someone else is still useful, provided you say who must approve it.
| Role in the case | What they typically can decide | What they typically cannot decide alone |
|---|---|---|
| Student group | How to divide work, how to communicate, what to ask the faculty | Grades, extensions, disciplinary outcomes |
| Branch manager | Local staffing within policy, local customer handling | Pricing policy, headcount budget, product changes set centrally |
| Plant director | Plant scheduling, maintenance, local safety actions | Group capital approvals, legal settlements, closure decisions |
| CEO | Strategy proposals, executive appointments | Matters reserved to the board, shareholders, regulators or statute |
These are general illustrations; real authority depends on the case facts. When the case is silent, state your assumption and say how the answer would change.
Step 5 — Analyse All Alternatives
Compare Alternatives Before Choosing
- 1.Generate feasible alternatives
- 2.Eliminate clearly unlawful or unethical choices
- 3.Compare cost, speed, evidence and stakeholder impact
- 4.Identify trade-offs and reversible pilot options
- 5.Select the strongest defensible alternative
In a case study group discussion, comparing multiple feasible options is more persuasive than advocating the first solution that sounds attractive.
Generate credible options before judging them. Check whether you have considered: maintain the status quo; incremental improvement; major transformation; hybrid solutions; temporary containment; long-term structural correction; and escalation for approval.
Compare using: feasibility, cost, time, resource availability, risk, stakeholder impact, legal compliance, ethical defensibility, reversibility, sustainability, implementation dependencies and likely unintended consequences.
Weighted decision matrix (PREPON instructional tool). Assign weights that add to 100, score each option 1 (poor) to 5 (strong), multiply and add. The weights are illustrative judgements, not facts. Change them and the ranking may change; that sensitivity is itself useful to discuss. Legal compliance and safety should act as gates: an option that fails them should not be rescued by high scores elsewhere.
Sample matrix (fictional café, illustrative weights):
| Criterion (weight) | Cut prices | Loyalty programme | Do nothing |
|---|---|---|---|
| Feasibility (20) | 5 | 4 | 5 |
| Cost / margin impact (25) | 1 | 3 | 5 |
| Speed of effect (15) | 4 | 3 | 1 |
| Risk (20) | 2 | 4 | 2 |
| Reversibility (20) | 2 | 4 | 5 |
| Weighted score (out of 5) | 2.65 | 3.60 | 3.80 |
Workings: Cut prices = (20×5 + 25×1 + 15×4 + 20×2 + 20×2)/100 = 2.65. Loyalty = (20×4 + 25×3 + 15×3 + 20×4 + 20×4)/100 = 3.60. Do nothing = (20×5 + 25×5 + 15×1 + 20×2 + 20×5)/100 = 3.80.
The matrix shows why numbers alone mislead: “do nothing” scores best here because it is cheap and reversible, yet it ignores the problem entirely. That is a signal to revisit the criteria, for example by adding “addresses the problem” as a gate. Use the matrix to structure the conversation, not to end it.
Why the first attractive option may not be best. It is often the most visible, not the most robust. Ask what would have to be true for it to work, and what happens if it does not.
Step 6 — Choose the Most Feasible, Win-Win and Ethical Alternative
Build a Defensible Final Recommendation
- 1.State the selected option
- 2.Explain the evidence and comparative advantage
- 3.Acknowledge affected stakeholders and trade-offs
- 4.Specify implementation and safeguards
- 5.Set measurable review and escalation triggers
The best conclusion to a case study group discussion explains the preferred option, why alternatives were rejected, what trade-offs remain and how implementation could be monitored.
Select the option, justify it with evidence, state the trade-offs, check legal and ethical limits, and then give an implementation plan, contingency measures and review indicators.
A win-win is desirable but not always available. Where interests genuinely conflict, do not manufacture a happy ending. Prioritise legal compliance, safety, rights and fairness, then minimise harm and distribute burdens transparently.
When the group cannot agree. Say so, and state the recommendation the majority supports, the main dissenting concern, what evidence would settle it, and a safe interim action. For example: “We agree on the first two weeks. We differ on whether to commit funds now; the disagreement turns on conversion data we don’t have, so we propose a gated decision after the pilot.”
7. Case Reading and Preparation Method
Timed Case Reading Workflow
- 1.Read the decision question first
- 2.Extract facts, constraints and missing data
- 3.Draft a one-sentence problem statement
- 4.Map stakeholders and authority
- 5.List alternatives and a provisional recommendation
- 6.Prepare a concise opening contribution
A timed case study group discussion rewards a concise preparation sheet that separates evidence, open questions and the key decision from distracting background details.
First reading (about one-third of your time). Read once for the story. Underline decision words (“should”, “must decide by”). Do not solve.
Second pass. Mark facts, numbers, dates, constraints, and who can do what. Note missing information.
Then fill the worksheet.
PREPON Six-Step Case-Analysis Worksheet
| Step | Write |
|---|---|
| Decision required | One sentence: “The decision is whether/how to …” |
| 1. Primary problem | Decision / symptoms / 2–3 possible causes |
| 2. Related problems | Associated: … Considered: … Resultant: now / if no action / from option |
| 3. Stakeholders | 5–8 names, with one overlooked stakeholder |
| 4. Decision-maker | Who decides, who approves, what I assume |
| 5. Alternatives | 3+ options, one-line pros/cons |
| 6. Recommendation | Choice, why, first action, risk, review indicator |
| First contribution | The sentence I will open with |
Illustrative time windows (not official standards; adapt to the actual exercise):
| Window | Priorities |
|---|---|
| 2 minutes | Decision sentence; 2 facts; who decides; one candidate action. Prepare to ask the group to agree the problem first. |
| 5 minutes | Add symptom/cause split, 5 stakeholders, 3 alternatives, one recommendation with a risk. |
| 10 minutes | Full worksheet; a mini matrix; numbers checked; first contribution written. |
What to write: key figures, dates, role names, constraints, your decision sentence, short option labels. What not to write: copied paragraphs, long sentences, solutions before diagnosis. Avoid over-noting: if you are writing more than you are thinking, stop. Numbers: compute simple ratios once (percentage change, per-unit cost, break-even), write the result and the unit, and flag any figure you are unsure of.
First contribution: prepare an opener that adds structure, such as: “Before solutions, can we agree what decision we’re making and who makes it?”
8. How to Participate Effectively
Productive Group Discussion Cycle
- 1.Listen and identify the current decision point
- 2.Offer one focused claim with a reason
- 3.Invite evidence or another perspective
- 4.Build on or respectfully challenge contributions
- 5.Summarise agreement and unresolved trade-offs
Strong performance in a case study group discussion combines precise reasoning with listening, respectful disagreement and contributions that help the group move forward.
Initiate. Frame, don't solve: "Shall we agree the decision first, then the facts, then options?" Avoid premature solutions. "I have a possible option, but I'd like to check the cause first." Evidence-backed points. Quote the case: "The case says deliveries slowed after the change; that suggests, but doesn't prove, a link." Build on others.
"Building on Meera's point about rider supply, we could check hours-logged-in." Ask relevant questions. "Do we know whether the delay is concentrated in batched orders?" Challenge assumptions. "We've assumed the manager can approve this. The case doesn't say so." Handle disagreement. Separate the claim from the person: "I see it differently.
Here is my reasoning." Include quieter participants. "Rohan, you've been thinking about the data. What do you see?" Prevent domination. "Let's hear two others before we decide." Redirect. "We've spent a while on the budget. Shall we return to stakeholders and then compare options?" Leadership vs control. Leaders help the group reach a good outcome; controllers push their own.
A facilitator says "Let me summarise; correct me." Propose alternatives. "There are at least three options: contain, change, or escalate." Summarise trade-offs. "Option B is faster but riskier; Option C is slower but reversible." Conclude professionally. "Our recommendation is X because Y; the main risk is Z; we'd review it after two weeks."
Claim → Reason → Evidence → Implication (PREPON communication tool)
Four-Part Speaking Structure
- 1.Claim: what should the group consider?
- 2.Reason: why does it matter?
- 3.Evidence: which case fact supports it?
- 4.Implication: what does it change in the decision?
Claim: “We should pilot before scaling.” Reason: “Because we don’t yet know whether the new line cannibalises the premium line.” Evidence: “The case gives no test data, and the premium brand carries most of the profit.” Implication: “So a limited pilot with defined stop criteria protects the core business.”
Ineffective statements and better alternatives
| Ineffective | Why weak | Better |
|---|---|---|
| “We should obviously fire them.” | Unsupported, premature | “Before we choose, can we list the legal and ethical limits on workforce reduction?” |
| “I agree with everything said.” | Adds nothing | “I agree with the pilot. I’d add a stop condition.” |
| “Technology is the future, so automate.” | Slogan | “Automation may cut cost, but we need the transition cost and legal obligations first.” |
| “Let’s just take a vote.” | Skips reasoning | “Shall we each state our top option and the biggest risk, then compare?” |
| Interrupting someone | Poor listening | “Sorry, may I add one point once Neha finishes?” |
Do not trade clarity for vocabulary. Simple, accurate sentences beat elaborate ones.
8A. PREPON Individual Candidate Assessment Rubric
How to Use the PREPON Practice Rubric
- 1.Observe one complete simulated discussion
- 2.Record evidence for each rubric criterion
- 3.Score behaviours rather than speaking duration
- 4.Give one strength and one improvement priority
- 5.Repeat a similar case and compare progress
A case study group discussion practice rubric should reward the quality of analysis and collaboration rather than the amount of time a candidate speaks.
This is a PREPON training tool. It is not an official scoring system adopted by any institution. Speaking more often does not earn a higher score, and agreeing with the group is not rewarded when the agreement is unethical or unreasoned.
Scale: 1 = Weak, 2 = Limited, 3 = Adequate, 4 = Strong, 5 = Excellent.
| Dimension | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|
| 1. Problem identification | Misses the problem or restates the symptom | Names a problem but confuses cause and decision | Identifies the decision and main symptom | Separates decision, symptoms, causes; flags uncertainty | Also tests competing framings and helps the group settle on one |
| 2. Analytical reasoning | Opinion only | Some reasons, gaps | Logical with partial evidence | Uses case facts and numbers; spots gaps | Rigorous, quantified where possible, states assumptions |
| 3. Stakeholder awareness | One group considered | Obvious groups only | Main groups with interests | Includes vulnerable or overlooked groups | Maps power, interest and conflict, and uses it in the solution |
| 4. Alternative evaluation | One option | Options named, not compared | Several options with pros/cons | Compares on stated criteria | Compares with trade-offs, gates and sensitivity |
| 5. Ethical judgement | Ignores ethics or endorses a harmful step | Mentions ethics superficially | Notices main ethical issue | Challenges problematic proposals | Resolves tension between ethics and feasibility with a workable alternative |
| 6. Communication clarity | Confusing | Understandable, rambling | Clear but unstructured | Structured and concise | Precise, structured, adapted to the group |
| 7. Active listening | Ignores others | Rarely references others | Sometimes builds on others | Regularly builds and clarifies | Integrates others’ points and revises own view |
| 8. Teamwork | Disruptive | Passive or competitive | Cooperative | Supports and shares airtime | Builds group momentum and cohesion |
| 9. Leadership and facilitation | Absent or controlling | Occasional steering | Some structure | Guides process without dominating | Consistently guides, summarises and brings the group to decision |
| 10. Decision-making | No position | Position without justification | Reasonable position | Justified position with risks | Justified, contingent, with review indicators |
Scoring rules. Score on observed behaviour in the transcript. The average is the sum of the ten scores divided by ten, shown to one decimal place. Averages are practice indicators, not predictions of selection.
(PREPON mentoring note: if you’d like a mentor to apply this rubric to your own recorded mock discussion, PREPON’s mentoring support is described at the end of this article.)

10. Common Mistakes and Faster Methods
Recover from a Weak Case Analysis
- 1.Spot the unsupported assumption or missed group
- 2.Return to the core decision problem
- 3.Check authority, constraints and stakeholder harms
- 4.Recompare the remaining realistic options
- 5.Restate a qualified recommendation
Many case study group discussion mistakes begin with premature certainty: a student asserts an unverified cause, overlooks a stakeholder or confuses a popular option with an ethical one.
| # | Error | Why it occurs | Consequence | Correction | Short example |
|---|---|---|---|---|---|
| 1 | Incorrect primary problem | Jumping on the first dramatic fact | Whole analysis solves the wrong thing | Write one decision sentence and get the group to agree it | “The problem is the algorithm” when the decision is what the City Head can do in 14 days |
| 2 | Confusing symptoms with causes | Symptoms are visible; causes need inference | Fixes that treat the surface | List symptoms and causes in separate columns | “Falling sales” treated as the cause of falling profit |
| 3 | Overlooking associated problems | Tunnel focus on the headline issue | Solution worsens a parallel problem | Ask “what else is going wrong around this?” | Fixing delays while rider attrition continues |
| 4 | Missing considered constraints | Budget is the only constraint remembered | Recommendation that is illegal, unsafe or unfundable | Run a law / safety / time / contract / capability / ethics / reputation check | Overtime plan ignoring working-hour limits |
| 5 | Ignoring resultant consequences | Optimism about one’s own option | Unintended harm | For each option ask “what could this cause?” | Rapid retrenchment causing disputes and skill loss |
| 6 | Incomplete stakeholder mapping | Listing only obvious groups | Harm to overlooked groups, weak buy-in | Add one overlooked group deliberately | Support agents, ongoing trial participants, contract workers |
| 7 | Wrong decision-maker | Assuming the role-holder has unlimited power | Recommendation nobody can approve | State who recommends, who approves, who must be consulted | A City Head “changing the algorithm” |
| 8 | Invented facts | Wanting a tidy story | Conclusions built on sand | Label assumptions as assumptions and say how the answer changes | “The competitor will surely cut prices” |
| 9 | False dichotomies | Time pressure | Missed hybrid or staged options | Ask for a third and fourth option, including “test first” | “Automate or die” |
| 10 | Premature solutioning | Wanting to look decisive | Group locks onto one idea | Say “I have an option, but first the cause” | Proposing rollback before checking the data |
| 11 | Impractical implementation | Strategy without logistics | Recommendation that cannot be executed | Add owner, first step, date, measure | “Improve culture” with no first action |
| 12 | Ignoring ethics | Treating ethics as a footnote | Harmful or non-compliant recommendation | Run a “would we defend this publicly?” test | Showing customers a false delivery time |
| 13 | Dominating the discussion | Equating airtime with leadership | Others disengage; analysis narrows | Invite two others before pressing your point | Repeating one’s view four times |
| 14 | Remaining silent | Fear of being wrong | No evidence of thinking | Prepare an opening structure; speak early with a framing point | Saying nothing until the last minute |
| 15 | Poor listening | Rehearsing the next point | Repetition, missed corrections | Paraphrase before responding | “As I said” about something already conceded |
| 16 | Repeating existing points | Wanting to be heard | Wasted time | Add a new fact, question or test | Restating the stakeholder list |
| 17 | Agreeing merely to obtain consensus | Wish to look cooperative | Unethical or weak decision | Agree on reasons, not on fatigue | Accepting a misleading claim to finish quickly |
| 18 | Weak conclusions | Running out of time | No recommendation | Reserve the last minutes for decision, reason, risk, review | Ending with “there are many views” |
Faster methods for experienced students
Faster does not mean shallower. These techniques compress the framework without dropping steps.
• The 30-second frame. Say: “Decision, symptom, possible causes, who decides?” The group usually fills the rest.
• Constraint sweep. Run six words in your head: law, safety, money, time, people, reputation.
• One overlooked stakeholder. Name one group nobody has mentioned. It signals depth and is often decisive.
• Three options minimum. Always include a “test first” or “staged” option.
• Gate check. Before scoring options, remove any that fail legal or safety limits.
• Closing template. “We recommend X because Y. The main risk is Z; we would review it by W. We disagree on V; the evidence that would settle it is U.”
11. Preparation and Improvement Plans
Practice–Feedback–Improvement Loop
- 1.Solve an unfamiliar case individually
- 2.Discuss it under timed group conditions
- 3.Review recording and candidate rubric
- 4.Prioritise one specific skill deficit
- 5.Repeat with a fresh case and measure improvement
A case study group discussion preparation plan should increase difficulty gradually and include recorded mock sessions, feedback and targeted correction of recurring errors.
Both plans are instructional suggestions. They are not guaranteed to produce any selection outcome. For related aptitude preparation, see PREPON’s Placement Aptitude Test Preparation.
A. 14-Day Foundation Plan
| Day | Focus | Exercise | Measurable outcome |
|---|---|---|---|
| 1 | Framework understanding | Read Sections 6–8; restate each step in your own words | Can explain all six steps without notes |
| 2 | Case reading | Read Case 1 twice; fill the worksheet in 10 minutes | Worksheet complete; decision sentence written |

12. Nine Additional Practice Cases
Practise each case study group discussion scenario independently before comparing the groups’ alternative decisions, assumptions and stakeholder analyses.
Each case below is fictional, deliberately incomplete, and meant to be discussed before looking at any worked answer. Timings are suggestions: adapt them to your own exercise. For safety-critical cases, the expected directions never involve harmful conduct or regulatory shortcuts.
Beginner
Practice Case 1 — The Stolen Recipe
Narrative. Aarti runs a small bakery and has built a loyal following around a signature cake recipe. A pastry chef, Naveen, who left three months ago to start his own café, is now selling a cake that tastes almost identical. A former colleague says Naveen “must have taken the recipe.” Aarti has no written confidentiality agreement with former employees.
Social media is buzzing, and Aarti is angry and thinking of posting a public accusation.
Candidate task. Advise Aarti on what to do in the next two weeks.
Constraints. Limited legal budget; no written agreement; reputation sensitive; evidence is only taste and word of mouth.
Suggested times. Preparation 5 minutes; discussion 15 minutes.
Competencies tested. Separating suspicion from evidence; ethics of public accusation; stakeholder thinking; proportionate response.
Instructor notes. Watch for groups treating suspicion as proof and for suggestions that defame or harass. Reward groups that ask what evidence exists and who else could have created a similar cake.
Expected analytical directions. What can be shown about copying? What are the legal and reputational limits on a public accusation? Which options protect the business without escalating (documentation, confidentiality practices going forward, differentiation, legal advice)? Who else is affected (staff, customers, Naveen)?
Practice Case 2 — The Campus Vendor
Narrative. A college canteen vendor has served students for ten years. The administration plans to replace him with a national food chain offering a wider menu at somewhat higher prices. Students are split: some want variety, some want to keep prices low and support the vendor, who employs four local workers. The student council must give the administration its recommendation within a week.
Candidate task. Recommend what the student council should tell the administration.
Constraints. The council advises; the administration decides. Contract terms are unknown. Survey data is limited.
Suggested times. Preparation 5 minutes; discussion 15 minutes.
Competencies tested. Decision authority; stakeholder balancing; fairness; collecting evidence quickly.
Instructor notes. Look for correct identification of the council as adviser. Do not reward a purely emotional position for either side.
Expected analytical directions. Quick survey on price, variety, quality and hygiene; a trial period or hybrid arrangement; protection or transition support for the vendor’s workers; transparency about the decision criteria.
Practice Case 3 — The Viral Complaint
Narrative. A customer posts a video on social media showing a hair in food at a restaurant chain’s outlet. It spreads widely. The outlet manager says the hair belonged to the customer. The chain’s regional head is under pressure from head office to “make it go away.”
Candidate task. Advise the regional head on responses over the next 48 hours and the next month.
Constraints. Facts are disputed; food-safety rules apply; the manager’s account has not been verified.
Suggested times. Preparation 5 minutes; discussion 15 minutes.
Competencies tested. Crisis response; honesty; service recovery; separating immediate and underlying problems.
Instructor notes. Watch for deleting evidence, attacking the customer, or “making it go away” by pressure. Reward investigation plus respectful public response.
Expected analytical directions. Acknowledge and investigate; check kitchen and hygiene practices; contact the customer privately; avoid blaming; review training and complaint handling; decide what to say publicly only once facts are checked.
Intermediate
Practice Case 4 — The Overperforming Toxic Manager
Narrative. A sales manager consistently exceeds targets and brings in the largest account. Three team members have separately told HR that he belittles them in meetings, and one has resigned citing his behaviour. His director says, “Results matter more.” HR has not yet recorded a formal investigation.
Candidate task. Advise the HR head on how to respond.
Constraints. The complaints are unproven; confidentiality and fairness to the manager apply; the company has a conduct policy; the director is senior to the HR head.
Suggested times. Preparation 7 minutes; discussion 20 minutes.
Competencies tested. Process fairness; organisational leadership; balancing performance and conduct; escalation.
Instructor notes. Do not accept “fire him” or “ignore it” without process. Reward attention to fair investigation, protection from retaliation and consistency with policy.
Expected analytical directions. Formal, impartial investigation; interim protection for complainants; clear conduct expectations and coaching if findings warrant; consequence framework; the risk to talent retention and legal exposure.
Practice Case 5 — The Delayed Product Launch
Narrative. A software company’s flagship update is four weeks behind schedule. Marketing has already announced the date to customers. Engineering says that releasing on time means skipping a full round of security testing. The CEO wants to protect the announced date, and a major client’s renewal depends on the launch.
Candidate task. Recommend a path to the CEO.
Constraints. Security testing cannot be skipped without risk; client trust is at stake; the team is already working overtime.
Suggested times. Preparation 7 minutes; discussion 20 minutes.
Competencies tested. Trade-offs under time pressure; ethical limits; communication with customers; realistic scoping.
Instructor notes. Reward options that protect security: phased release, reduced scope, honest communication. Penalise recommendations to bypass testing.
Expected analytical directions. Scope reduction versus delay; staged rollout; how to tell the client; what the delay costs versus what a breach could cost; team fatigue.
Practice Case 6 — The Supplier Dilemma
Narrative. A garment exporter’s main fabric supplier has delivered late twice and just announced a 12% price increase. A cheaper alternative supplier is available but has not been audited for labour and environmental compliance, which key overseas buyers require. The exporter has a large order due in eight weeks.
Candidate task. Advise the procurement head.
Constraints. Buyer compliance requirements; fixed order date; limited negotiating leverage; limited audit time.
Suggested times. Preparation 7 minutes; discussion 20 minutes.
Competencies tested. Supply-chain risk; compliance; negotiation; contingency planning.
Instructor notes. Watch for treating the cheaper supplier as an obvious answer without audit. Reward conditional and staged recommendations.
Expected analytical directions. Negotiate with the current supplier; rapid compliance audit of the alternative; split sourcing; early talks with buyers; cost versus penalty risk.
Advanced
Practice Case 7 — The Sovereign Wealth Fund
Narrative. A foreign sovereign wealth fund offers a large investment in a struggling Indian infrastructure company. The offer comes with a board seat and an option to raise its stake later. The company needs cash to avoid defaulting on loans within six months. Critics worry about influence over a strategically sensitive asset. Regulators have not yet been consulted.
Candidate task. Advise the company’s board on how to respond.
Constraints. Foreign-investment rules and sectoral approvals may apply and must be confirmed by counsel; the default deadline is real; the company’s other options are limited.
Suggested times. Preparation 10 minutes; discussion 25 minutes.
Competencies tested. Governance; regulatory awareness; negotiation; strategic and national-interest considerations.
Instructor notes. Do not accept any recommendation that ignores regulatory approval or assumes it is automatic. Reward conditional acceptance with safeguards and alternative financing.
Expected analytical directions. What approvals are required; control and governance terms; alternative funding and lender negotiations; stakeholder views (employees, lenders, regulators, the public).
Practice Case 8 — The M&A Culture Clash
Narrative. A traditional manufacturing company has acquired a young technology firm to speed up digitalisation. Six months in, key tech staff are resigning, citing rigid processes and slow decisions. The manufacturing leadership says the tech staff “lack discipline.” The deal’s value depends on retaining a few critical engineers.
Candidate task. Advise the integration committee.
Constraints. Retention agreements expire in three months; each side holds different values; leadership is divided.
Suggested times. Preparation 10 minutes; discussion 25 minutes.
Competencies tested. Change management; organisational culture; integration planning; people-focused analysis.
Instructor notes. Watch for blaming one side. Reward diagnosis before solutions and evidence-gathering such as exit interviews.
Expected analytical directions. Separate causes (process, leadership, pay, autonomy); selective autonomy for the tech unit; leadership alignment; retention incentives paired with real changes; metrics for integration.
Practice Case 9 — The AI Triage System
Narrative. A hospital network is considering an AI system to prioritise emergency-room patients. In a pilot, it reduced average waiting times, but an internal review found it assigned lower priority more often to patients from one language group because of how symptoms were recorded. Management wants to proceed as the pilot saved costs.
Candidate task. Advise the hospital’s leadership on whether and how to proceed.
Constraints. Patient safety is paramount; clinicians remain responsible for decisions; medical-device and data-protection rules may apply and must be confirmed by qualified advisers.
Suggested times. Preparation 10 minutes; discussion 25 minutes.
Competencies tested. Safety-critical judgement; fairness and bias; governance; clinical accountability.
Instructor notes. Do not accept deployment on cost grounds while a fairness or safety problem is unresolved. Reward recommendations to pause or restrict use, investigate the cause, involve clinicians and affected communities, and set monitoring and approval conditions.
Expected analytical directions. Nature and cause of the disparity; clinician override and oversight; independent evaluation; interim manual processes; regulatory and legal checks; communication to patients and staff.
13. Self-Assessment Framework
Post-Mock Self-Assessment Loop
- 1.What decision did I identify?
- 2.What evidence and stakeholder concerns did I contribute?
- 3.Did I listen, build on others and manage disagreement?
- 4.Was my recommendation feasible and ethical?
- 5.What exactly will I improve in the next mock?
After a case study group discussion mock, assess what you contributed, which assumptions you challenged and how effectively you helped the group evaluate choices.
After any mock discussion, work through this checklist honestly.
Before the discussion
• Did I write one decision sentence?
• Did I identify who decides and who recommends?
• Did I prepare an opening framing statement?
During the discussion
• Did I separate decision, symptom and cause aloud?
• Did I raise at least one stakeholder nobody else had?
• Did I use Claim → Reason → Evidence → Implication at least once?
• Did I ask a question about missing data?
• Did I challenge an assumption respectfully?
• Did I change my mind when the evidence changed?
• Did I draw in a quiet member or avoid dominating?
After the discussion
• Score yourself on the ten rubric dimensions and ask one peer to do the same.
• Where do you differ by two points or more? Look at the recording, not your memory.
• Write one improved sentence for your weakest moment, then rehearse it.
A useful target is steady improvement in your own scores over time, not any particular number.
14. Academic Foundations
Psychological safety, groupthink and decision biases can illuminate a case study group discussion, but no academic theory should be presented as proof that the PREPON framework is an official assessment method.
General research on groups and decisions can help you understand why case discussions go wrong. It does not validate the PREPON six-step method, and none of these authors designed or endorsed it. It is also general organisational research; it is not evidence about how any Indian admissions or recruitment process assesses candidates or about selection outcomes.
• Groupthink. Irving Janis described how cohesive groups can suppress dissent and settle on poor decisions. In practice: value a respectful challenge, and do not agree just to finish.
• Heuristics and biases. Amos Tversky and Daniel Kahneman showed how mental shortcuts such as anchoring can distort judgement. In practice: the first attractive option may be anchoring.
• Stakeholder theory. R. Edward Freeman argued that organisations should consider all those affected by their decisions. In practice: Step 3.
• Psychological safety. Amy Edmondson’s research links a team climate in which members can speak up to better learning. In practice: invite quieter voices.
• Integrative negotiation. Roger Fisher and William Ury distinguished positions from underlying interests. In practice: look for options that serve interests before choosing between positions.
• Bounded rationality. Herbert Simon argued that decision-makers have limited information and time and often settle for good-enough choices. In practice: be explicit about assumptions and about what you could not check.

15. Frequently Asked Questions
What is a case study group discussion?
It is a group exercise in which participants analyse a supplied scenario and discuss what the decision-maker should do. See Section 2.
Do all MBA programmes use case study discussions?
No. Selection formats differ by institution and year. For example, the IIM Ahmedabad PGP 2026–28 shortlisting document identifies an Analytical Writing Test and a Personal Interview, not a Case Study GD. Check each institution's current official notice.
How is a case discussion different from a traditional GD?
A case discussion gives you the facts and usually expects a decision. A traditional GD is usually opinion-based on a topic. See Section 4 and PREPON's <a href="https://prepon.in/blog/group-discussion-for-mba-admissions/">Group Discussion for MBA Admissions</a>.
How should I start a case study discussion?
Frame, don't solve. Propose agreeing the decision, the key facts and who decides before discussing solutions.
What if the group cannot agree?
State the majority recommendation, the main dissenting concern, the evidence that would settle it and a safe interim action (Step 6).
Is a win-win solution always possible?
No. When interests conflict, prioritise legal compliance, safety, rights and fairness, then minimise harm and share burdens transparently.
How much should I speak?
Enough to add value. In the PREPON rubric, speaking more often does not earn a higher score; clarity, listening and judgement matter more.
How can I practise alone?
Use the worksheet in Section 7 on the practice cases, record your Claim → Reason → Evidence → Implication statements, and self-assess with the checklist in Section 13.
Are the sample scores real or official?
No. They are fictional PREPON training illustrations and do not represent any institution's scoring.
What are the six steps in PREPON’s case study group discussion framework?
Identify the primary decision problem; distinguish associated, considered and resultant problems; map stakeholders; identify the primary decision-maker; analyse realistic alternatives; and recommend the most feasible, fair and ethical option.
What is the difference between a problem, symptom and root cause in a case?
A symptom is visible evidence that something is wrong, a root cause is a possible explanation, and the primary problem is the decision the authorised person must make. Do not treat an unverified explanation as a fact.
How do I identify stakeholders in a case study?
List everyone who may affect or be affected by the decision: customers, employees, management, suppliers, regulators and communities as relevant. For each, note their interests, exposure to risk and decision-making influence.
Who is the primary decision-maker in a case study discussion?
The individual or body that has the authority and responsibility to make the decision in the scenario. Distinguish formal authority from stakeholders who may influence or implement that decision.
How do I compare alternatives during a case discussion?
Compare viable options against consistent criteria such as feasibility, resources, timing, safety, legality, stakeholder effects and reversibility. State the trade-offs rather than presenting only benefits.
How should I handle missing information in a case study?
Separate supplied facts from assumptions. Explain which additional evidence would affect the decision, and use conditional recommendations when uncertainty is material. Avoid inventing numerical outcomes.
What should I do if another participant interrupts me?
Briefly acknowledge the point, complete your essential idea in a sentence, then invite the group to build on it. If interruptions continue, return to the case and avoid personal confrontation.
How can I contribute when someone else has already suggested my solution?
Add value by identifying a stakeholder, testing an assumption, comparing a competing option, naming an implementation risk or synthesising the emerging consensus. Repeating the same recommendation is less useful.
How should I conclude a case study group discussion?
Summarise the primary decision, the strongest alternative and why it was selected, its ethical and practical trade-offs, the immediate action plan and any unresolved risk. Distinguish consensus from unresolved disagreement.
16. Conclusion
A good case discussion is not won by the fastest voice. It is won by the group that frames the decision clearly, tests its assumptions, remembers the people affected, respects who actually decides, compares real options and recommends something defensible, including when no perfect answer exists.
The six steps give you a way to do that under time pressure; the companion case studies and transcripts show what it looks like when it goes well and when it does not.
