BrandenKowitz. Shortening the build-measure-learn cycle with clickable mockups.
I’m sold on testing with high fidelity mock ups. For me it’s really useful and it cuts the time that I had to figure out what’s working and what’s not, just like what Kowitz wrote.
The quote above reminds me of a reading that was assigned for another class – Krug’s Usability testing on 10 cents a day. He drew a chart to outline and demonstrate the difference between one test on 8 persons, and two tests for 3 persons, and the problems found. He concluded that it’s better to test twice with less number of people than doing one test with many people. The reason being that you can find the unseen problems in phase one of testing the second time round, making it more efficient.
Also this particular paragraph really stick with me:
"Testing reminds you that not everyone thinks the way you do, knows what you know, uses the web the way you do.
I used to say that the best way to think about testing was that it was like travel: a broadening experience. It reminds you how different and the same people are, and gives you a fresh perspective on things. But I finally realized that testing is really more like having friends visiting from out of town. Inevitably, as you make the tourist rounds with them, you see things about your home town that you usually don’t notice because you’re so used to them. And at the same time, you realize that a lot of things that you take for granted aren’t obvious to everybody.”
- Steve Krug. P.134.
This quote is so true. During user testings, in my first phase of fidelity mockups, I didn’t include any descriptions for the icons on the tabs. The minimalist in me took it for granted that since it’s the standard iOS icons, everybody would know what they mean. Turns out there was a considerable pause before tapping the icons, as if they aren’t sure if the icons still function the same way.
