In-Depth Activity
In this activity, think about the case studies and reflect on the evaluation methods used.
For the two case studies discussed in this chapter, think about the role of evaluation in the design of the system and note the artifacts that were evaluated: when during the design were they evaluated, which methods were used, and what was learned from the evaluations? Note any issues of particular interest. You may find that constructing a table like the one shown here is a helpful approach.
Name of the study or artifact evaluated When during the design the evaluation occurred? How controlled was the study and what role did users have? Which methods were used? What kind of data was collected, and how was it analyzed? What was learned from the study? Notable issues
What were the main constraints that influenced the evaluations?
How did the use of different methods build on and complement each other to give a broader picture of the evaluations?
Which parts of the evaluations were directed at usability goals and which at user experience goals?
