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?
