How can they do it? A structured approach to the strategies analysis phase of Cognitive Work Analysis

Abstract

Cognitive work analysis is a widely applied method within Human Factors. To date, applications have mainly focused on the first two stages of the method – Work Domain Analysis and Control Task Analysis. The latter stages have been neglected and are consequently not as well developed methodologically. This paper proposes an approach for strategies analysis, the third phase, which builds upon the output of the earlier phases and provides a structured, repeatable method for identifying potential strategies for completing control tasks. An Apple iPod is used to exemplify and evaluate the proposed approach. Future directions include validation of the approach with more complex systems.
