Abstract : Researchers need better measures for evaluating human performance in complex socio-technical systems. A constraint-based and a task-based method were compared for their effectiveness in identifying measures that would be sensitive to a system modification. Working in an advanced simulator, aircrews conducted tactical missions with or without a modification to a specific aircraft system. Across two experiments there was no significant difference between the methods in the sensitivity or suitability of the measures that they suggested. Nonetheless, observations made during the program of research suggested that the constraint-based method for identifying measures is a viable alternative to the task-based method.
