1. The document discusses different strategies for choosing test users for user testing, including testing with exact target demographics, representative users, primary and secondary personas, and by test object. 2. It emphasizes the importance of getting feedback from real users over making assumptions, and recommends testing early and often with both expert and non-expert users. 3. Key tips include choosing smaller, iterative tests over extensive studies, and recognizing that UX is an ongoing process so testing shouldn't be delayed until feeling fully ready.
![The last thing you want to hear during a usability study
session is a participant saying,
“I don’t use this kind of [system],” or “I never do that
[task] for my job.” That person cannot help you discover
the problems with that system or how well the system
supports users’ tasks.

- 1. Reto Lämmler • UXCamp Hamburg 2015 @rlaemmler @testingtime Blind Dates – Or the right choice of test users
- 2. Why do I want to talk about this?
- 3. The UX industry still designs too much based on assumptions.
- 4. Talking to a user is worth more than a thousand assumptions.

- 17. Jacob Nielsen About simplified User Testing The three main rules: 1. Get representative users 2. Ask them to perform representative tasks with the design 3. Shut up and let the users do the talking.

- 20. The right choice of test users
- 21. Recruit Test Users by Category
- 22. Test Users by Category Consumers vs Experts Consumers • Shopping • News • Travel • Social • Entertainment • … Experts • Medical • Engineering • Architecture • Finance • Legal • …
- 23. Experts are also Consumers But Consumers are not always Experts. Expert Consumer Everyone can be potentially recruited to test a consumer application. E.g. A neuro scientist uses www.travel.ch Only Experts from the field can be recruited to test an Expert application. E.g. A neuro scientist uses NemoDevices.
- 27. Recruit Test Users by Personas & Scenarios
- 28. Test Users by Personas Primary vs. Secondary vs. Other Personas Primary Secondary or Supportive Non- Personas
- 30. Primary and Secodary Personas With some example scenarios in mind Primary Personas • Experienced Kiter who wants to purchase a new Kite • Newbie Kiter who wants to find a beginners course • … Secondary Personas • A worried parent who wants to learn about the sport • Godfather who wants to find a gift for a godchild • …
- 31. Supportive and Non-Personas With some example scenarios in mind Supportive • Site Manager who maintains the inventory • Human Resources maintaining job listings • … Non-Personas • …?
- 32. Recruit Test Users by Test Object
- 33. Website, App, Documentation Test objects Website / App Navigation Content Accessibility Task Completion
- 35. … … Devices Packaging, Food, Devices Test objects Food … Packaging …
- 36. Recruiting service for UX people
- 41. When do you blind date and when do you choose carefully?
- 42. My Learnings And recommendations • It’s still better to test with anyone, than no testing at all There is always something you can learn. • Choose smaller tests over extensive studies But iterate as often as necessary • UX is not a project, it’s an ongoing process So don’t excuse it with «I’m not ready yet.»
