Failure Modes and Effects Analysis (FMEA) has long been a core part of the hazard analysis procedures
conducted in the design of high-reliability or safety-critical hardware systems. More recently, it has been
applied to the analysis of software functions to examine the effects of failures in software. However,
approaches that account for operator behaviour as a determinant of overall system safety have not been
developed to the same degree, and the effect of the operator on system "safety" is often handled in an ad-hoc
manner with little rigour. In this paper we propose an FMEA-like approach by analysing the interaction
between operator and device. We discuss how such an approach would fit into current hazard and safety
analysis procedures, develop the approach using a model of user behaviour that originates from work in
cognitive science, and demonstrate how this could be used by working through an example analysis based on
a real-world system
