Test Goals


The type of usability test chosen depends primarily on the goal of the test as well as the product's development stage. A test can follow two goal strategies in the evaluation of the product, and it is essential that the usability experimenters decide before the test takes place as to the nature of their evaluation. This is important as it becomes increasingly difficult and disorderly if a dramatic shift is made in the goal of the test while the test is taking place. While the tasks and the features of the products can be changed around, it is important that the primary goal of the test be either on improvement of the product or comparing different alternatives.
