Observers

The best policy with observers is to keep them away from the testing session. Most people get nervous when they sit a test, or know they are being watched by a large group of people.

Instead, use a camcorder to record the testing session for later review.

This has a number of advantages:

You'll have the option to review a particular testing session over and over again
All members of the design team can dicsuss a testing session as they are reviewing it
