Small Business Case Study Writing, From Owner Interview to Draft

What makes a small business case study different

Three things set these cases apart: the evidence base is thin, the owner is both your best source and the gatekeeper to everything else, and family or personal dynamics sit inside the business instead of outside it. A listed company hands you annual reports and an investor relations page. A corner bakery hands you one interview, a shoebox of invoices and a cousin who does the payroll. Your job is to write a rigorous analysis anyway — and to be honest about where the rigor comes from.

Markers grade small business case studies on the same rubric as any other case: framing, evidence, analysis, recommendation. What changes is the texture. Here is how each difference plays out on the page.

Data scarcity is the norm, so treat it as a feature

You will rarely get audited statements. You might get a spreadsheet the owner trusts, a card reader summary, or a rough turnover figure quoted from memory. The mistake students make is smoothing this over — rounding a guess into a precise-looking number and hiding the source. Do the opposite. Write "estimated by the owner, who tracks the figure for tax purposes" and your credibility goes up, not down. A short methods note explaining where every number came from is the cheapest way to earn marks on a data-poor case.

The owner interview is your main instrument

Forty-five minutes with the person who signs the checks beats a week of desk research on a five-person firm. Prepare like a journalist, not like a form-filler: ask about a specific week, a specific customer, a specific decision that went wrong. Recording beats note-taking if the owner agrees. And keep analytical distance — the owner's story is evidence, not a finding. "Sales dropped because the roadworks hurt foot traffic" is a claim you test against whatever you can observe, not a sentence you copy into your diagnosis.

Family dynamics are data, not gossip

In a family business, who does what is often a map of who trusts whom. A son who runs deliveries but cannot touch pricing, a founder who still approves any spend over a threshold, a spouse who keeps the books — these are operating constraints. Markers notice when a recommendation ignores them. "Hire a full-time operations manager" reads naive if the case tells you the founder refuses to delegate. Name the constraint, then design around it.

Check what evidence you actually have

Before you plan a single section, take stock. Tick everything you can get your hands on — the tool adapts its advice to your situation. Most small business cases start with an interview and not much else, and that is workable.

The five-step approach, as a working checklist

This is the sequence that survives contact with a real deadline. It differs from the generic case-study routine because steps two and four lean on access most corporate cases never need. Tick items off as you go — the bar tracks your progress.

Writing progress0 of 5 steps

• Frame the decision the business actually faces. One sentence, not a topic. "Should the bakery open a third site or push catering from the existing two?" beats "growth at the bakery". Every later section exists to answer this sentence.
• Run the owner interview and record it (with permission). 30–45 minutes, prepared questions, one on a week that went wrong. Note the exact phrasing of anything quotable and the date — you will cite it.
• Pull whatever numbers exist and label their source. Card-reader totals, payroll run, a margin the owner quotes from memory. Build one simple exhibit instead of many shaky ones, and say where each figure came from.
• Map the ownership and family picture before you analyse. Who decides, who can veto, who is irreplaceable. Then check your draft recommendation against that map — if it needs powers nobody in the case has, rewrite it.
• Write a recommendation the owner could start on Monday. Small firm, small levers: one change, an order of magnitude of cost the business can carry, and how you would know in a month whether it is working.

Show the evidence, not the interview

The most common written symptom of a data-poor case is a paragraph that just reports what the owner said. Markers read it as transcription. The fix is to attach the claim to something checkable — a number, a pattern, a consequence. Compare the two versions below, both built on the same fact from an illustrative café-and-bakery case.

A worked mini-outline you can copy

Here is the shape that fits most briefs between 1,500 and 3,000 words — check yours, because the weighting shifts the middle sections. The worked example below uses an illustrative two-shop family bakery deciding between a third site and a catering push. It is a teaching example, not a real company.

Four pitfalls that sink small business cases

Each of these shows up in every marking season. They are avoidable at the drafting stage if you know what they look like.

Tools that carry their weight here

Three free tools from this site do disproportionate work on a small business case. The SWOT analysis generator suits owner-run firms well because a small business's strengths and weaknesses are unusually concrete — one van, one baker, one loyal customer block. Fill it with case evidence, not adjectives. The word counter keeps the 1,500-to-3,000-word budget honest, which matters here because interview quotes eat space fast. And if your brief wants a defensible claim rather than a summary, the thesis statement generator turns your decision framing into a sentence you can actually argue. For the surrounding structure — sections, exhibits, referencing — the full how to write a case study guide has the detail this page assumes.
