What Is a Case Study?
A case study is an in-depth, detailed examination of a particular subject — an organisation, individual, event, decision, policy, period, project, or phenomenon — within its real-world context. Unlike experimental research, a case study does not control variables or produce generalisable statistical findings. Instead, it seeks depth of understanding: what happened, why it happened, what decisions were made, what outcomes resulted, and what can be learned from it.
Case studies are among the most widely used assessments in business, management, law, social work, nursing, education, and public policy programmes. They test your ability to apply theoretical frameworks to real situations, make evidence-based judgements, and communicate complex analysis clearly and concisely.
| Purpose | Description |
|---|---|
| Exploratory | Investigates a phenomenon to inform future research; used when little is known. |
| Descriptive | Provides a detailed account of a real-world situation without drawing broad conclusions. |
| Explanatory | Examines cause-and-effect relationships within a complex situation. |
| Evaluative | Assesses the effectiveness of an intervention, policy, or decision. |
Academic vs Business Case Studies
While they share structural similarities, academic and business case studies have different audiences, purposes, and conventions.
Academic case studies
Written for an academic audience — professors, journals, programme assessors. They are expected to draw explicitly on theory, use formal academic language, include in-text citations and a reference list, and engage critically with complexity rather than oversimplify to a "best answer." The analysis is typically more tentative and hedged because the academic goal is understanding, not prescription.
Business case studies
Written for a practitioner audience — managers, consultants, investors, clients. They are typically more action-oriented, with clear recommendations that can be implemented. Language is more direct. While theoretical frameworks may be used, they are usually applied as tools rather than discussed in depth. Business case studies in MBA programmes blend both traditions.
An MBA case study at a top business school expects explicit use of frameworks like Porter's Five Forces and a clear recommendation with financial justification. An undergraduate sociology case study expects theoretical positioning, nuanced analysis, and critical reflexivity. Read the assignment brief carefully — the same topic can require very different treatments.
Choosing a Case
If you are free to choose your own case, select one that is: information-rich (you can find enough credible data to support your analysis), directly relevant to the topic or module you are addressing, bounded enough that you can analyse it thoroughly within your word limit, and not so familiar that your analysis risks being a recap of what everyone already knows.
Types of cases
- Typical case: Represents a common pattern within a larger category. Useful for illustrating how something usually works.
- Atypical / deviant case: An outlier — a company that succeeded where others failed, or failed where others succeeded. Often the most analytically interesting.
- Critical case: A case that clearly confirms or refutes a theoretical claim. Powerful for theory-testing.
- Revelatory case: A previously inaccessible phenomenon now available for study. Often used in innovation research.
Case Study Structure
The standard case study structure follows a logical narrative: background establishes context, the problem section identifies the issue at the centre of the analysis, analysis applies frameworks and evidence, recommendations propose solutions, and the conclusion synthesises the findings.
Background / Context
Who is the organisation or subject? What is the industry, sector, or situation? What is the time frame? Keep this factual and concise — it sets the scene but doesn't do the analysis.
Problem / Issue Identification
What is the central problem or decision the case presents? Be specific. A vague problem leads to unfocused analysis. "The company faced challenges" is not a problem statement; "declining market share in a commoditising industry despite sustained R&D investment" is.
Analysis
Apply relevant analytical frameworks (SWOT, PESTLE, Porter's Five Forces, Value Chain, etc.) to the case. This is the core of the work — the section that demonstrates your analytical ability. Frameworks should illuminate the problem, not simply be listed.
Options / Alternatives
In business case studies especially, present 2–3 alternative courses of action and evaluate the pros and cons of each before recommending one. This demonstrates that you considered options, not just stated an obvious answer.
Recommendations
Based on your analysis, what should be done? Recommendations must be specific, actionable, justified by your analysis, and realistic given the constraints of the situation.
Conclusion
Synthesise the key analytical findings and restate the core recommendation. Acknowledge limitations of your analysis and note what additional information would improve it.
Analysis Frameworks
Analysis frameworks are structured tools that help you examine a case systematically. Choosing the right framework depends on the nature of the problem. Using a framework doesn't mean completing a template — it means using it as a lens to generate insights, then discussing those insights analytically.
SWOT Analysis
SWOT (Strengths, Weaknesses, Opportunities, Threats) is an internal-external framework used to assess an organisation's competitive position. Strengths and weaknesses are internal; opportunities and threats are external. The value of SWOT is in the cross-matrix — how can strengths be used to exploit opportunities (SO strategy)? How can weaknesses be addressed to avoid threats (WT strategy)?
PESTLE Analysis
PESTLE (Political, Economic, Social, Technological, Legal, Environmental) examines the macro-environmental factors affecting an organisation or situation. Use it to identify external forces the organisation cannot control but must respond to. Every factor you include should be clearly linked to its impact on the case — don't just list generic current events.
Porter's Five Forces
Michael Porter's framework analyses the competitive structure of an industry by examining five forces: threat of new entrants, bargaining power of suppliers, bargaining power of buyers, threat of substitute products or services, and intensity of competitive rivalry. Each force is rated as high, medium, or low, with justification. The combined rating indicates overall industry attractiveness and informs strategic choices.
| Framework | Best used for | Typical case context |
|---|---|---|
| SWOT | Assessing an organisation's position | Strategic planning decisions |
| PESTLE | Mapping external environment | Market entry, policy impact, industry trends |
| Porter's Five Forces | Industry structure analysis | Competitive strategy, entry/exit decisions |
| Value Chain | Internal operations analysis | Cost leadership, differentiation strategy |
| BCG Matrix | Portfolio analysis | Multi-product company strategy decisions |
| McKinsey 7S | Organisational alignment | Change management, restructuring |
Many students complete a SWOT or PESTLE and then treat their case study as finished. The framework output is not the analysis — it is the raw material for analysis. After completing any framework, you must interpret the results: what do these findings mean together? What is the strategic implication? What does theory say about situations like this?
Citing Evidence in a Case Study
A case study is an evidence-based document. Every factual claim about the case — revenues, market share figures, strategic decisions, outcomes — must be supported by a credible source. In academic contexts, this means proper in-text citations and a reference list. In business contexts, sources are typically footnoted or listed at the end.
Types of evidence in case studies
- Primary sources: Annual reports, press releases, financial statements, interviews, internal documents, direct observation.
- Secondary sources: News articles, academic papers analysing the organisation, industry reports (IBISWorld, Mintel, Euromonitor), analyst commentary.
- Theoretical sources: Academic texts that provide the framework you are applying (e.g., Porter, 1980 for Five Forces; Barney, 1991 for resource-based view).
When you apply a framework, cite the original source. Saying "the company faces high supplier power (Porter, 1980)" signals to your marker that you are applying an established framework correctly. It is a small touch that significantly improves academic credibility.
Writing the Recommendations
The recommendations section is where many case studies succeed or fail. Strong recommendations are: specific and actionable (not "improve communication" but "implement weekly cross-functional briefings between product and marketing teams"), grounded in the analysis you conducted, realistic given the constraints you identified, and prioritised so the reader knows what to address first.
Structuring individual recommendations
For each recommendation, provide: (1) what you recommend, (2) why — linked to your analysis, (3) how it would be implemented at a high level, (4) expected outcomes or benefits, and (5) potential risks or trade-offs. This structure signals thorough, critical thinking rather than surface-level prescription.
Strong: "Given the SWOT analysis identified declining customer acquisition in the 18–34 demographic as a key weakness, and the PESTLE flagged increased social commerce adoption as an opportunity, we recommend a 12-month pilot of shoppable Instagram and TikTok content targeting this cohort, with a budget allocation of 15% of the current digital marketing spend, measured by cost-per-acquisition against the existing baseline."
Case Study Report vs Essay Format
Whether to write your case study as a formal report (with headers, numbered sections, and bullet points) or as a continuous essay depends entirely on your assignment brief. These are two genuinely different formats with different conventions.
| Feature | Report Format | Essay Format |
|---|---|---|
| Structure | Numbered headings, sub-headings, may include tables and bullet points | Continuous prose, no numbered headings |
| Language | Direct, concise, business-style | Academic prose, formal but flowing |
| Executive Summary | Often required (150–250 words) | Not used — introduction instead |
| Tone | Objective, action-oriented | Critical, analytical, sometimes tentative |
| Common in | MBA programmes, business school assessments | Undergraduate social science, law, education |
Common Case Study Mistakes to Avoid
- Describing instead of analysing: Lengthy description of what happened without engaging with why it happened or what frameworks reveal. Markers want analysis, not a retelling of events.
- Framework completion without interpretation: Completing a SWOT table and submitting it without drawing analytical conclusions from it.
- Generic recommendations: Recommending things that any company in any situation should do ("improve communication," "invest in training"). Recommendations must be specific to this case and grounded in your analysis.
- Ignoring constraints: Proposing solutions that are financially, legally, or practically impossible given the case context. Show you understand the real-world limits.
- No evidence for factual claims: Citing statistics about a company's performance or market position without attributing them to a source. This fails academic integrity standards.
- Word count imbalance: Spending 80% of the word count on background and only 20% on analysis and recommendations. Invert this ratio — analysis and recommendations deserve the most space.
