| Summary: | This research modified two analysis techniques, goal-directed task analysis (GDTA) and modified cognitive work analysis (mCWA), in order to apply them to the analysis of a complex team-based system. Traditionally, GDTA and mCWA have been applied to narrowly focused physical-based domains; however, the chemical, biological, radiological, nuclear and explosive (CBRNE) incident response domain is a very complex domain in which individual humans and teams of humans with specialised skills and responsibilities are considered to be system components. The resulting system combines very large number of components, decision-makers and uncertain environmental issues. Each analysis technique provided strengths that complemented the other's weaknesses; however, the analysis techniques required augmentations in order to facilitate information capture and correspondence to design requirements. The contributions of this article include a presentation of the augmentations and a discussion of the benefits provided by employing both analysis techniques.
