DescriptionThe recent Boeing 737MAX accidents crystalized for the public the complexity of anticipating system and operator performance and developing a system design that prevents catastrophic outcomes. The operational situations, progression of flightcrew actions, and system behaviors that led to the two accidents had not been anticipated by the manufacturer or the regulator. These accidents were only the most recent examples of our failure to anticipate and manage operational complexities and operator performance. In this panel, we offer different perspectives on risk/safety assessment as it relates to operator performance in complex systems, e.g., Human Reliability Analysis (HRA), complexity analysis, and STAMP. Foundational to assessment is deciding the nature of safety and the role of operator performance. An important question is, “What guidance can we give to industry and regulators regarding how to measure safety and how to decide that action is required on the basis of safety?”
