Abstract
The overall intent behind the Cognitive Function Model (CFM) application is to guide the human factors analyst towards identifying highly challenging cognitive tasks or functions, and to provide indicators that guide the analyst in choosing which tasks or functions to pursue using Cognitive Task Analysis (CTA), in order to make the best use of available time and resources. We developed a computer-based application using a CFM approach. CFM links the Operator Function Model (OFM) and the Cognimeter Screening Tool. The Cognimeter is intended to bridge the gap between OFM (traditional task decomposition) and Cognitive Task Analysis. In addition, the Cognimeter provides the human factors analyst with the means to identify the high pay-off cognitive challenges from a functional decomposition or systems engineering representation of a system (in this case, OFM representations).
