A structured approach to the strategies analysis phase of cognitive work analysis

Abstract

Cognitive work analysis is a widely applied method within Ergonomics. To date applications have primarily focused on the first two stages of the method – Work Domain Analysis and Control Task Analysis. Compared to the initial stages, the latter stages have been relatively neglected and are consequently not as well developed methodologically. This paper proposes a new approach for the third phase, strategies analysis, which builds upon the output of the earlier phases and provides a formative structured method for identifying potential strategies to complete 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.
