Toward a Categorization of Factors related to Procedure Following and Situation Awareness

Procedures are used as prescribed action lists to help human operators remember and follow mandatory steps that guarantee safety, workload and performance criteria. This paper presents a categorization of situation awareness factors and suggestions for improving the design of both the procedures and the user-interface in new generation fligh-decks. These categories were constructed from the result of a previous study (de Brito, 1998). should improve concurrent human-centered design of procedures and interface, to contextualize procedures training, to operationalize electronic procedures, and to integrate the revision process. The repercussions on the life cycle of a safety-critical system include concurrent design of procedures and interface, contextualized procedures training, operationalized electronic procedures, and integrated revision process.
