ABSTRACT
This chapter addresses how Cognitive Work Analysis (CWA) can be used for the purposes of analysis, informing design, and evaluation. The approach has been applied to two examples, a Helicopter Mission Planning System, and a battlefield command and control system. The first case study identifies opportunities for design improvements, the detailed look at the social organisation and cooperation analysis (SOCA) phase of the analysis also encourages the analyst and the designer to consider how the implications of; location, time and actor can influence the design of the system. The SOCA phase raises questions about the correct mix of cooperation and collaboration as well the suitability of distributed working practices. The second case study provides further description of the Work Domain Analysis phase in a new domain. The chapter also introduces the concept of using the Abstraction Hierarchy to generate measures of performance; these measures can be used in a survey of subject matter experts.
