Comparing, Merging, and Adapting Methods of Cognitive Task Analysis

Cognitive systems engineering projects have found a need for and a value in combining particular methods of cognitive task analysis (CTA). A principle reason that is given is that different CTA methods have different strengths in terms of how they inform the study, analysis or design of cognitive work systems. Focus questions include: What specific CTA methods have been combined or merged for some particular research project? What was the rationale for the selection of methods? How did researchers do the combining? Were methods actually merged into a single procedure, or were multiple methods conducted separately, what the resulting analyses or representations merged subsequently?
