A strong case study starts with a useful conversation, not a request for praise. Ask questions that uncover the client's before-and-after story.
“Can you give me a testimonial?” is a small question with a weak result.
It asks the client to write your case study for you. Most people respond with a compliment, not evidence.
A better approach is a short interview focused on the change your work helped create.
Ask about the starting point
“What was happening before we began?” helps the client describe the original constraint in their own words.
Ask what the problem affected: decisions, delivery, confidence, customer experience, or team capacity.
Ask what changed during the work
Find the turning point. What did the client see, decide, or do differently? This is more useful than a chronological project recap.
Ask for the concrete result
Use prompts such as “What can you do now that was harder before?” or “What changed for the team after the work?”
If there is a number, ask how it was measured. If there is not, a specific behavior or decision is still valuable proof.
Ask what they would tell a peer
“Who would benefit from this kind of help, and why?” gives you a natural description of the best-fit client without forcing marketing language.
Make approval easy
Send a draft that distinguishes direct quotes from your summary. Ask the client to correct anything inaccurate and confirm what they are comfortable publishing.
The goal is not to make the client praise you. It is to help a future client recognize their own problem in a real story.
