•
Are participants doing what was expected?
Did anything cause frustration or confuse?
Anything new or surprising?
Any paths that you haven’t thought of before?
Was there a clearly preferred solution or path?
Are some paths unused or “misused”?
17. Reflection and Design Changes
E.g.
Bottlenecks in the process?
What paths were ignored or barely used?
What was clearly missing? etc.
Tip: Update before the next test user and see if it worked.
