Cognitive Infomation Flow Analysis for Emergency Evaluation
The Cognitive Information Flow Analysis (CIFA) is a method to combine results from multiple cognitive task analyses while providing a focus on the necessary system information flow, which includes how information is produced, consumed, and transformed by the various system functions and users. This project explored the CIFA concept, conducted a case study that applies the CIFA method to existing Goal-Direct Task Analysis and modified Cognitive Work Analysis results, and investigated CIFA’s use for informing the design of a system of human-robot interfaces.
CIFA can serve as a guide for system design and development. CIFA also provides a number of advantages over combining cognitive task analysis results using relational tables. First, CIFA can express the interconnectivity of the various system subcomponents, including partial ordering and parallelism, by fundamentally focusing on the information flow. Second, CIFA can identify both existing and potential, information bottlenecks and highlight teamwork.
