Case Study Thesis Guide | Case Boundary, Evidence Chain, Protocol, and Within-Case Analysis

Direct answer for this topic

Plan a case study thesis by defining the case boundary, collecting interview and document evidence, building a case protocol, and connecting within-case analysis to theory.

• Case boundary and unit of analysis
• Interview, archive, and observation evidence
• Within-case analysis and evidence chain
• A case study thesis investigates a bounded company, organization, event, policy, class, community, or project.

A case study starts from a bounded case

A case study thesis investigates a bounded company, organization, event, policy, class, community, or project. The first task is to define what counts as the case, what stays outside the boundary, and which unit of analysis will carry the argument.

Unlike an abstract-writing guide, this page is about research design and evidence handling: how to select a case, build a case record, triangulate sources, and turn field material into analysis.

Case study research protocol

• Case boundary: define location, time period, organization, event, and excluded materials
• Research question: explain why this case can reveal a mechanism, contradiction, or process
• Evidence plan: list interviews, documents, reports, media records, observation notes, or datasets
• Coding frame: decide whether the analysis follows chronology, theme, actor, or mechanism
• Verification: use source triangulation and negative evidence to prevent one-sided interpretation

How to select and justify the case

• Typical case: suitable when the goal is to explain a common phenomenon
• Extreme case: useful when a high-contrast case exposes a hidden mechanism
• Critical case: chosen because it can confirm, challenge, or refine a theory
• Revelatory case: justified when the researcher gains access to material rarely available
• Comparative cases: use the same boundary rules so cross-case comparison remains valid

Build the evidence chain before writing

The case description should be backed by a traceable evidence chain: where the fact came from, whether another source confirms it, and how it supports the later analysis.

Separate raw facts from interpretation. Timelines, actor maps, interview excerpts, document tables, and event sequences make the analysis more auditable than a purely narrative description.

Within-case analysis and theory connection

Within-case analysis explains how the case developed over time or how different actors, resources, and constraints interacted. The theory should help interpret evidence, not simply decorate the chapter.

Useful frames include process tracing, mechanism analysis, stakeholder analysis, policy implementation analysis, and organizational diagnosis. Choose the frame because it fits the case question.

Writing notes

• Case description should be objective, avoid excessive subjective evaluation
• Theory and case must be closely combined, do not discuss theory detached from case
• Conclusions must be derived from case analysis, not pulled out of thin air
• Note to protect business secrets and personal privacy involved in the case

Frequently asked questions

Can case study thesis include quantitative analysis?

Yes. Case study does not equal qualitative analysis. You can introduce quantitative data into cases, such as financial analysis, survey data. Quantitative and qualitative methods can be combined.

Must cases be from your own research?

Not necessarily. Cases can come from public sources (like listed company annual reports, news reports), or from your own research primary data. Using primary data when possible is recommended as cases are more authentic.

What is the difference between MBA thesis and regular master case studies?

MBA thesis emphasizes practicality and application, requiring specific management suggestions; regular master emphasizes theoretical contribution and academic standards. MBA thesis cases can be larger and more complex.
