ABSTRACT

Cognitive task analysis (CTA) outputs are used, amongst other things for interface design and evaluation, the design of procedures and processes, allocation of functions, the design and evaluation of training procedures and interventions, and the evaluation of individual and team performance within complex systems. CTA methods are useful in evaluating individual and team performance, in that they offer an analysis of cognitive processes surrounding decisions made and choices taken. The task diagram interview is used to provide the analyst with an in-depth overview of the task under analysis. During the task diagram interview, the analyst highlights those elements of the task that are cognitively challenging. In order to prepare for the Applied CTA (ACTA) data collection phase, it is recommended that the analyst(s) involved observe the task or scenario under analysis. The ACTA method also employs various data collection techniques, such as walkthrough and observation.
