Prepare• Write a simple script for yourself, if you have a

lot of testing to do. Number/name questions and tasks to help documentation.

• Write down tasks on a separate paper so you can show them to your test participants

• Specify, for yourself, end-results for the task. Think about what “task not completed”could stand for.

Test session

Page 16: Testing Paper Prototypes (IxDworks.com)

During the test pay attention to...

E.g.

• 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”?

Page 17: Testing Paper Prototypes (IxDworks.com)

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.
