The active role of participants and facilitators

The roles and experiences of both the user and facilitator within the usability testing process need to be considered as an active, contributory factor in the outcomes of traditional usability testing. When a user comes into our test lab to volunteer for a usability testing session, we need to acknowledge that they are a not simply a unanimous voice of our audience but a person entering a novel environment, with all of the concerns and behaviours that entails.
