Usability testing at a cafe
Boris Masis, Google Developer Relations Program Manager gave a ”show and tell” about “Guerilla Testing with Usability Cafe,” an example that shows that user testing does not have to be a time consuming activity. And you will save time in you project by performing usability testing, and as I said in my last post, the earlier you do the usability test, the better (click here to read the whole post).
He mention in the clip below that it’s important to offer the test persons a small treat.
An interesting take away from this video is that you can find up to 85 percent of usability problems by observing five people who use an app. It might not work the same way with a more complicated systems. What do you think? If it is a system that performs a lot of different tasks, I think it could take more than five people to test it and more time, but when it comes to an app, I think this is fun to watch and that its a good point.
Enjoy some usability testing out in the wild 🙂
