ABSTRACT
This chapter describes an exercise intended to validate and extract key requirements for the Cognitive Work Analysis (CWA) software tool. The first phase of CWA, the Abstraction Hierarchy (AH), is used to describe the domain in event independent terms. Here the physical units and their capabilities are captured. The tool also has clear advantages over drafting software packages such as Microsoft Visio; the ability to pass information forward within the phases was extremely valuable in the process of expediting the documentation. The functions for the CAT were imported directly from the AH; the AH and the CAT products were reused in the Social Organisation and Cooperation Analysis phase. The process was successful in its main aim; the software tool was able to support the development of the required documentation and some clear recommendations for incremental changes were made for the tool improvement.
