Turn an idea into questions
A useful first test checks one uncertainty. Do people experience this problem? Can you reach them? Will they use the proposed solution? Can you deliver it at an acceptable cost? Write each question separately so that positive feedback on one does not become “proof” of all the others.
Ask about behaviour, not compliments
- “Tell me about the last time this happened.” Follow up on what the person did, the time it took and what remained unresolved.
- “What do you use today?” Include doing nothing, borrowing, informal help and competing services.
- “Who decides and who pays?” Avoid asking someone to predict another person’s purchasing decision.
Ask permission before recording. Keep only the notes you need. Do not put names, phone numbers or sensitive personal stories into a public case study without appropriate permission.
Choose a test with an observable result
Use a sketch, a sample session, a demonstration or a manually delivered service where suitable. Decide in advance what you will count: attendance, task completion, repeat use or another relevant action. A social-media like and a paid order are different signals.
Keep the result honest
Record people who declined, dropped out or could not use the solution. Compare the result with your original question. If the test failed, identify whether the problem, audience, price or delivery needs to change. Avoid collecting more favourable comments merely to defend the original idea.
