ABSTRACT
This chapter introduces cognitive work analysis (CWA) in the context of system analysis and design. The benefits of CWA are realised when the framework is used to design new and first-of-a-kind systems. The five main phases of CWA such as work domain analysis [WDA], control task analysis [ConTA], strategies analysis [StrA], social organisation and cooperation analysis [SOCA] and worker competencies analysis [WCA] can feed supportive information into all aspects of system design. As a test case, CWA was applied to the Trafalgar-class power plant. The chapter explores the usefulness of the resultant products of the preliminary analyses, paying particular attention to its role in informing design decisions, in particular, those identified by early human factors analysis (EHFA): target audience description (TAD), concept of operations (CONOPS), function analysis, normal and emergency operations, allocation of function, workload assessment and training needs analysis and so on.
