How to Attempt a Case Study Group Discussion: Complete Preparation Guide

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

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

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

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

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

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

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

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

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

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)

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

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.)

9. Six Solved Case Studies — Companion Article Library

10. Common Mistakes and Faster Methods

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

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
3	Problem classification	Re-read Cases 2 and 3; sort items into associated / considered / resultant	At least 80% of items match the case answer key, or you can justify differences
4	Stakeholder analysis	Build a matrix for Case 4 before reading its solution	Name at least two overlooked stakeholders
5	Decision authority	For Cases 1–4, list who decides, who approves, who is consulted	Correct recommender / approver split for each
6	Alternative evaluation	Generate four options for Case 5 and score them with your own weights	Weights written and justified; one gate identified
7	Review and rest	Revisit mistakes from Days 2–6	Error list of at least five items
8	Ethical judgement	Take Cases 5 and 6; write what you would refuse to recommend, and why	One written ethical limit per case
9	Verbal articulation	Record yourself giving a Claim → Reason → Evidence → Implication on three cases	Each recording under 60 seconds, all four parts present
10	Mock discussion 1	Run a 20-minute discussion with 3–5 peers on Practice Case 1	Recording and notes saved
11	Assessment	Score yourself with the rubric; ask a peer to score you independently	Gaps between self and peer scores noted
12	Targeted repair	Redo the weakest dimension with a fresh case	One improved sample statement per weak dimension
13	Mock discussion 2	Run another discussion on Practice Case 2 or 3	Compare with Day 10 recording
14	Reassessment	Re-score both mocks; write a one-page learning summary	Clear list of three strengths and three priorities

B. 30-Day Improvement Plan

Week	Focus	Exercises	Measurable outcome
1	Analytical complexity	One intermediate practice case every two days; write a full worksheet and a weighted matrix	Matrix with illustrative weights and one gate in each
2	Active listening and conflict	Mock discussions where each speaker must paraphrase the previous speaker before replying; one assigned “disagreeing” role	Observer counts paraphrases and constructive challenges; target at least three per person
3	Time-bound cases and advanced simulations	Practice with 5-minute preparation and 15-minute discussion on advanced cases; follow with a full self-evaluation	Recommendation stated before time runs out in every session
4	Recording, review, correction, reassessment	Record two full mocks; transcribe key exchanges; fix errors using Section 10	Re-score against the rubric and compare with Week 1; record the change in each dimension

Each week, keep an error log (what went wrong, why, correction), and a phrase bank of structures that worked for you.

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

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

01What 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.

02Do 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.

03How 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>.

04How should I start a case study discussion?

Frame, don't solve. Propose agreeing the decision, the key facts and who decides before discussing solutions.

05What 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).

06Is a win-win solution always possible?

No. When interests conflict, prioritise legal compliance, safety, rights and fairness, then minimise harm and share burdens transparently.

07How 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.

08How 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.

09Are the sample scores real or official?

No. They are fictional PREPON training illustrations and do not represent any institution's scoring.

10What 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.

11What 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.

12How 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.

13Who 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.

14How 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.

15How 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.

16What 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.

17How 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.

18How 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.
