 Overview

During a usability test, let the test users interact with the system first, so that they get familiar with it and acquire some expertise in accomplishing tasks using the system. Then introduce a naive user to each test user. The Novice users are briefed by the tester to limit their active participation and not to become an active problem-solver. Each test user is asked to explain to the novice how the system works and demonstrate to him/her a set of pre-determined tasks. This technique can be used for the following development stages: design, code, test, and deployment.
