Blind Dates – Or the right choice of test users
Why do I want to talk about this?
The UX industry still designs too much based on
assumptions.
Talking to a user is worth more than a thousand
assumptions.

About meTest early, test often.
Why user testing?

“There are some times when it’s important to test your product with your exact market, and other times when users from any demographic can give you the feedback you need.”

What does Jacob think?
Jacob Nielsen About simplified User Testing
The three main rules:1. Get representative users2. Ask them to perform representative tasks with the
design 3. Shut up and let the users do the talking.
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.

When do you blind date and when do you choose
carefully?
My LearningsAnd 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 studiesBut iterate as often as necessary
• UX is not a project, it’s an ongoing processSo don’t excuse it with «I’m not ready yet.»
