Roles of the pracitioners during a usability test

  • Test monitor
  • Data logger
  • Timers
  • Technician
  • Video operator
  • Observer

Most tests do not require individuals to play all of these roles. For example, the video operator may not be needed if the session is not videotaped. Also, one individual may play multiple roles. For example the technician could also be a timer.

The test monitor has the most important role. Here are some of the challenges that the test monitor faces:

  • Make the participant feel comfortable with the test
  • Minimize distractions towards the user
  • Refrain from guiding user through usability obstacles
  • Attend to cues that indicate problems
  • Remember actions and problems

In addition to this list, Rubin provides an extended discussion of problems encountered by test monitors.
