Cognitive Task Analysis (CTA) is a recognized technique for analyzing how people operate within a specific task domain and with a specific toolset. In this paper we introduce an improved variant, Comparative CTA (C2TA) that allows the separation of effects due to basic human cognition from those due to the toolset. An example from weather forecasting is provided, including sample results and recommendations that would not have emerged from traditional CTA.
