Getting past first base: Going all the way with Cognitive Work Analysis.
This paper reports the application of Cognitive Work Analysis (CWA) to the problem of communications planning in military aviation. Applications of CWA rarely get beyond the first one or two phases; this paper presents an analysis in which all five phases have been completed. The method offers a formative description of the system, defining the set of boundaries and constraints that shape system activity in terms of work domain, recurring activities, decision making, social organisation and worker competency requirements. It is an analysis that is well suited to environments in which the occurrence of unanticipated events can have serious implications for both safety and productivity. Communications planning in military aviation is such an environment. The outputs of the analysis provided an extensive and exhaustive description of the system, highlighting the uneven spread of activity, across actors involved in communications planning and across the situations in which planning can occur. In addition, a new method for informing worker competency requirements based on abstract functions rather than specific decision steps is proposed and discussed in terms of job design, interface design, and person specification.
