ABSTRACT
Cognitive task analysis (CTA) techniques are useful in evaluating individual and team performance within complex systems. They offer an analysis of cognitive processes surrounding decisions made and choices taken. These insights allow practitioners to design fit for purpose environments and to develop guidelines for effective performance in complex urban settings. The main problem associated with the use of CTA techniques is the considerable amount of resources required. CTA methods are commonly based upon interview and observational data, and therefore require considerable time and effort to conduct. Access to subject matter experts (SMEs) is also required, as is great skill on the analyst’s behalf. CTA techniques are also criticized for their reliance upon the recall of events or incidents from the past.
