As I have said before, taking notes is rife with danger. It’s so tempting to just write down everything that happens. But you probably can’t deal with all that data. First, it’s just too much. Second, it’s not organized.
Let’s look at an example research question: Do people make more errors on one version of the system than the other?
And we chose these measures to find out the answer:
- Count of all incorrect selections (errors)
- Count and location of incorrect menu choices
- Count and location of incorrect buttons selected
- Count of errors of omission
- Count and location of visits to online help
- Number and percentage of tasks completed incorrectly
