Note for seminar 2, Marcus

Chapter 13 tells us about evaluation and what it means. Why, what, where and when to evaluate is the basic to ensure that the customers gets what they need. These terms are quite self-explaining but necessary. Evaluation is how to improve and understand an existing design for a user and how to enchant the experience. A product can be compared for improvement or made to fill the demand. Usually the requirement are low at start and designers have to rethink and customize for the user in order to improve.

When the prototype is done, the next step is to test the design in different environment.  This can be done in tree ways. “Controlled settings involving users”, “Natural settings involving users” and “Any setting not involving users”. “Controlled” are often done in laboratory or other controlled areas, “Natural” in public areas, and the “Any settings” are focused on predicting the user’s behavior.

In chapter 15 we are introduced to different evaluation methods. One is called heuristic evaluation and are done with designers and experts role-playing as users to predict and interact in different ways and understand the flaws in the design. Another method is walkthroughs, which simply evaluate in a specific order see if the design meet any user problems. 

Question: Should your evaluation be done with a fixed number of people or include as many as possible?
