Write a customer case study from an interview recording

The raw material for a great case study is usually sitting in one 30-minute call. The hard part is turning a rambling transcript into a clean story without putting words in the customer's mouth.

Time30 minutes
You needAn interview transcript, the customer's permission, and any AI assistant

Steps

  1. Get the customer's permission to publish before you start writing.
  2. Get a transcript of the interview. Most video call tools and note-takers can produce one.
  3. Paste the prompt with the transcript.
  4. Check every quote against the transcript word for word. This matters more than anything else in the playbook.
  5. Send the draft to the customer for approval before it goes anywhere public.

Draft the case study
Here is a transcript of an interview with a customer about how they use our product:
[PASTE THE TRANSCRIPT]

Write a case study draft with these sections:
1. The situation before, in the customer's terms
2. What they tried and why it did not work
3. What changed after they started using us
4. The result, using only numbers the customer actually said
5. Three short direct quotes, copied exactly from the transcript

Strict rules: never invent a number or a quote. If a section has no support in the transcript, write "Not covered in interview" so I know to ask a follow-up question.

What a good result looks like

An illustrative example. The company and figures are made up.

Before: the team kept client briefs in email threads, and new starters had to ask around to find anything. What they tried: a shared drive, which filled up and was never tidied. What changed: every brief now lives in one place with the same structure. Result: "We stopped losing the first week of every project hunting for information." Quote: "The new hires just open it and get going. That never happened before."

Make it better

  • Ask it which follow-up questions would give you a stronger result section, then send them to the customer.
  • Ask for a 50-word version as well. That is the one that gets used on the website and in sales decks.
  • Put the best quote at the top. People read the quote before they read the story.

Before you paste anything, remove details you would not share outside your company, such as customer names, contract terms or personal information. How to use AI at work safely
