Until recently, I captured all my data from interviews, contextual inquiries, walkthroughs, and user testing in Word. For each participant, I’d type my observations etc. into a copy of the test plan. At the end I was left with many many documents which I would print out, spread across my desk, and stare at.
I became dissatisfied with this form of analysis. It resists rigor. So during the second to last round of testing I did, I put all my Word notes into an Excel document to make comparisons more effectively. It was lovely. It took a lot of effort with all that copying & pasting, but it was worth it.
