[Sigia-l] Participants in Iterative Testing Sessions

[Whitney Quesenbery]

Patrick -

What's the context of use and who are the target users?

I'd want to ask questions like:
Small or large target user groups? Specialized or general demographics?

However:
Unless you are conducting very large scale usability tests, you will 
probably find more advantage in having different users for each one, 
increasing the number of test participants.
