ABSTRACT
This chapter discusses the application of Cognitive Work Analysis (CWA) in a simplistic, familiar domain. The case study uses the first three phases of CWA to explore the constraints governing the use of the Apple iPod. The analysis describes the constraints governing how activity is conducted in an actor independent way. The Work Domain Analysis describes the relationship between what the physical objects in the system can perform, and what the system is required to perform. The Control Task Analysis (ConTA) describes situations in which the iPod is constrained in its functionality, such as charging the battery on the move and uploading music whilst away from a computer. Strategies Analysis is used to look in more detail at known recurring activities. This stage of the analysis considers the tasks analysed in the ConTA phase and considers the strategies that are likely to be used to complete them.
