What Makes a Good Case Study?

A great case study tells a before-and-after story with specific, measurable outcomes. The reader should be able to see themselves in the "before" situation and understand clearly what changed and why. Vague claims ("we improved efficiency") are forgettable. Specific results ("reduced processing time from 4 hours to 45 minutes") are compelling.

Standard Case Study Structure

  1. 1

    Title and summary

    A one-sentence headline that leads with the result: "How [Company X] Increased Revenue by 40% in 6 Months" is more compelling than "Company X Case Study." Include a 2–3 sentence executive summary for readers who will not read the whole piece.

  2. 2

    The client/subject

    Briefly introduce who the case study is about: industry, company size, relevant context. One short paragraph. The reader needs just enough context to understand the challenge.

  3. 3

    The challenge/problem

    Describe the specific problem or situation in detail. Make it relatable β€” readers should recognise similar challenges. Include: what was happening, why it was a problem, what had already been tried and why it had not worked. The more specifically you describe the problem, the more credible your solution appears.

  4. 4

    The solution

    Explain what was done and why. Be specific about the approach, tools, methodology or process. Do not oversimplify β€” readers want to understand how the problem was solved. Include any challenges encountered and how they were addressed.

  5. 5

    The results β€” the most important section

    Lead with the most impressive numbers. Use specific metrics: percentages, time saved, revenue generated, cost reduced, satisfaction scores. Include a before/after comparison. Quote the client or subject directly if possible β€” third-party validation is more credible than your own claims. A results section with no numbers is a weak case study.

  6. 6

    Quote and conclusion

    A direct quote from the client or stakeholder adds authenticity. Close with a brief summary and ideally a broader takeaway or lesson applicable to similar situations.

For academic case studiesAcademic case studies typically follow a more structured format: introduction, literature review, methodology, findings, analysis, recommendations and conclusion. Follow your institution's specific requirements and citation style. The principles of specificity and evidence remain the same.

Frequently Asked Questions

Business/marketing case studies: 500–1,500 words with visuals. Shorter is usually better β€” busy readers will not read a 3,000 word case study. Academic case studies vary by discipline and assignment brief but are typically 1,500–5,000 words. Always follow any word count guidelines provided.
Always ask explicitly and get written consent. Many clients are happy to be featured β€” it is good publicity for them too. Offer to share the draft for their approval before publishing. Some clients prefer to be anonymised β€” "a large Australian retail chain" instead of naming them. Respect these preferences.
