If you are working on your MBA dissertation, one of the first big decisions is how you will collect and analyse your evidence. Many students assume a dissertation needs a large survey with hundreds of responses, so a study built around one company feels risky. The good news is that case study research is accepted on most MBA programmes, and when it is done properly it can score very well. If you are looking for MBA dissertation help to decide on your approach, this guide explains when a case study works, when it does not, and how to build one your supervisor will respect.
The Short Answer
Yes, you can. A case study is a recognised research strategy in business and management. Your university may have preferences, so check your programme handbook and talk to your supervisor early. But the method itself is well established, and many MBA students choose it because it lets them study a real organisation in real depth.
What Case Study Research Actually Means
A case study is an in-depth investigation of one organisation, a small group of organisations, a project, a decision or a process, inside its real setting. You are not trying to count how many people agree with a statement. You are trying to understand how and why something happened.
Examples that suit an MBA level:
- How a retail company changed its supply chain after a major disruption
- Why a digital transformation project in a hospital trust stalled
- How a family business handled leadership succession
Notice that each one asks "how" or "why". That is the signal that a case study may fit.
Why Business Schools Accept It
Business problems rarely happen in a lab. They happen inside companies, with real people, budgets, politics and deadlines. A case study lets you look at all of that together. It also matches how MBA programmes teach, since most of your coursework already uses cases.
The method also has a strong academic base. Robert Yin's work on case study design is the most cited starting point, and Kathleen Eisenhardt's paper on building theory from case studies is widely used in management research. Citing sources like these in your methodology chapter shows you did not just pick the method because it looked easy.
Single Case or Multiple Cases
Single case. You go deep into one organisation. This works well when the case is unusual, very typical, or gives you access to something few people can see.
Multiple cases. You compare two to four organisations. This gives you stronger evidence for patterns, but it takes more time and more access, so be realistic about your timeline.
For most MBA dissertations, one well-chosen case or a small comparison of two or three is enough. Going wider usually means going thinner.
Case Study vs Survey: A Quick Comparison
| Point | Case Study | Survey |
|---|---|---|
| Main question type | How and why | How many and how much |
| Sample | One to a few organisations | Large group of respondents |
| Data | Interviews, documents, observation | Questionnaire responses |
| Strength | Depth and context | Breadth and statistical testing |
| Main weakness | Hard to generalise | Limited depth |
| Best for | Understanding a process or decision | Testing relationships between variables |
Neither is better in every situation. The right choice depends on your research question.
When a Case Study Is a Good Fit
- Your question starts with "how" or "why"
- You can get access to an organisation or enough public information about one
- The topic is hard to measure with numbers alone
- You want to understand a process, not just an outcome
When You Should Think Twice
- You want to prove a cause and effect relationship with statistics
- You cannot get any access to people or internal documents
- Your question is really about a whole industry or country
- You only plan to describe a company without any analysis
If your plan is just "I will write about Company X," that is a company profile, not a case study. A case study needs a clear question, a method and an argument.
How to Build a Strong Case Study Step by Step
1. Write a focused research question. Keep it narrow. "How did Company X manage change during its ERP rollout?" is workable. "How do companies manage change?" is too wide.
2. Choose your case and explain why. Do not pick a company only because it is famous or easy. State your selection logic. For example, it may be a typical example, an extreme example, or the only one you can access.
3. Plan your data sources. Strong case studies use more than one source. Common options are:
- Semi-structured interviews with managers or staff
- Annual reports, internal policies and meeting records
- Public sources such as press releases and regulator filings
- Direct observation, if you are allowed on site
4. Triangulate. This means checking one source against another. If a manager says a project went smoothly but the documents show repeated delays, that difference is worth discussing. Triangulation is one of the best ways to show your findings are credible.
5. Choose your analysis method before you collect data. Thematic analysis is common for interview data. Pattern matching, where you compare your findings with a theory you set out in advance, is also widely used. For multiple cases, you can add a cross-case comparison.
6. Link back to theory. Your case should talk to the literature. Show where your findings agree with existing models, where they differ and what that might mean.
Ethics and Access
This is where many case study plans fall apart. Before you contact anyone, check your university's ethics process. You will usually need:
- Permission from a gatekeeper at the organisation
- A participant information sheet and consent form
- A plan for anonymity and secure data storage
Some companies will agree to talk only if their name is hidden. That is fine. Many dissertations use a pseudonym and describe the sector and size instead. Just make sure the organisation cannot be easily identified if you promised anonymity.
How to Write the Methodology Chapter
Your supervisor will look for justification, not just description. Cover these points:
- Your research philosophy and approach, for example the layers in Saunders' research onion
- Why a case study fits your question better than other strategies
- Your case selection logic
- Data collection methods and sample details
- Your analysis steps
- Validity, reliability and limitations
- Ethical approval
Write it in the past tense if your university expects it, and keep your language plain. A methodology chapter that is clear and honest usually scores better than one filled with heavy terms.
Dealing With the Generalisability Problem
The most common criticism of case studies is that you cannot generalise from one organisation. Do not hide from this. Address it directly in your limitations section.
A good answer is that case studies aim for analytic generalisation, not statistical generalisation. You are not claiming that every company will behave the same way. You are using the case to test, refine or extend a theory, and you explain what other organisations in similar conditions might learn from it.
Common Mistakes to Avoid
- Choosing a case with no clear link to the research question
- Relying on a single interview and calling it a case study
- Using only company websites as evidence
- Describing events without analysing them
- Skipping the ethics process until the last minute
- Writing a findings chapter that is just a long quote dump
Quick Checklist Before You Commit
- Is my question a "how" or "why" question?
- Do I have realistic access to the case?
- Have I planned at least two data sources?
- Do I know how I will analyse the data?
- Has my supervisor seen and agreed with the plan?
- Have I started the ethics form?
If you can answer yes to most of these, a case study is likely a safe and strong choice for your MBA dissertation.
Final Thoughts
Case study research is a valid and respected option for an MBA dissertation. It rewards students who ask clear questions, collect evidence carefully and explain their choices honestly. It does not reward shortcuts. If you plan it well, it can also give you something useful beyond the grade, which is a detailed understanding of how a real business works.
