The longer you wait, the less you test

The following is a guest post by Reto Lämmler, CoFounder and CEO of TestingTime. Enjoy the read.

To get interaction design right, we prototype and test with users. It mostly starts with pen and paper, sketching a first prototype which gets tested with friends and coworkers. Once the first interaction flaws are discovered, we iterate towards HiFi prototypes using tools like Pidoco. Every iteration requires user testing in theory, but do we really do that? Do we take the time to recruit the right people?

I have done many prototypes and user tests in the past. For me, the best user tests are always those which give me the big “AHA” moment. When I discover a problem which I never thought would be a problem for test users. It’s an exciting moment and reinforces how important user testing is.


Though, I discovered one interesting thing. Interaction and visual designers are not always keen to test their prototypes with users. Everyone talks about it but not so many really do it. Why is this? I have come to 2 conclusions:

We want to make it perfect, before we show it

We constantly think, it’s not good enough before we show it to anyone. The longer we wait, the more we get stuck in this mindset. We become afraid of getting critical feedback which may throw our work upside down and the invested time turns into waste. Our assumption of “perfect” is based on our mental model and usually doesn’t match with the one from your target users. Break that barrier as early as possible and make it a habit to show and user test your work starting with your first scribbles.

It’s too cumbersome or we are simply too lazy

We know that we should carry out user tests, but we don’t practice what we preach. Sometimes we don’t have time and postpone it for later. Recruiting test users can be very time consuming and cumbersome. This is why we invented a crowd-based recruiting service called It’s takes you less than 5 minutes to order your desired test users for moderated remote user tests. It’s not only fast, it’s also inexpensive. Using TestingTime, you can carry out rapid user testing for every design iteration you go through.

Looking for test users for your next usability test?

If you need test users to test your Pidoco prototypes, why not try out TestingTime’s recruiting service to find test participants from your target audience without the usual hassle. Visit TestingTime or email for more information.
