    18.1. Goal-directed UX evaluation

    18.1. Goal-directed UX evaluation

    The bottom line for developing the evaluation plan is to be flexible and do what it takes to make it work. We have given you the basics; it is up to you to come up with the variations. Adapt, evolve, transform, invent, and combine methods (Dray & Siegel, 1999). For example, supplement your lab-based test with an analytical method (e.g., your own UX inspection).

    18.1.1. No Such Thing as the “Best UX Evaluation Method”

    When you seek a UX evaluation method for your project, it usually is not about which method is “better,” but which one helps you meet your goals in a particular evaluation situation. No existing evaluation method can serve every purpose and each has its own strengths and weaknesses. You need to know your goals going in and tailor your evaluation methods to suit.
