Evaluation is the fourth main process of interaction design. By evaluation we mean reviewing, trying out or testing a design idea, a piece of software, a product or service to discover whether it meets some criteria. The main points are: Designers need to focus hard on what features of a system or product they want to evaluate. They need to think hard about the state that the system, service or product is in and hence on whether they can evaluate those features. Data Analytics is important for evaluation. There are expert-based methods of evaluation. There are also participant-based methods of evaluation. Designers need to design their evaluation to fit the particular needs of the contexts of use and the activities that people are engaged in.
