There are many test activities that go on during the Analysis phase:
The user profile need to be validated by either going into the
field and making sure they are accurate portrayals, and/or shoeing
them to users
It is critical that current and future task descriptions be
verified with users
Usability specifications need to be verified and agreed to by
users
Use case scenarios need to be verified with users. If the software
developers are using scenarios for their architecture design, then
they need to verify and agree to the scenarios as well.
