Human error identification techniques for risk assessment of high risk systems--part 2: towards a framework approach

This is the second paper in a series of two, reviewing human error identification approaches for risk assessment of high risk socio-technical systems. The previous paper identified and reviewed thirty-eight techniques. One of the closing comments was that no single technique sufficed for all the practitioner's needs, and that a potential way forward was to utilise a number of techniques in a toolkit fashion, or to develop a new framework-based or toolkit-based approach. This paper therefore describes in detail a framework approach developed for the UK nuclear power and reprocessing industry, showing the practical implementation of such a system. It then considers some of the advantages and disadvantages of such framework approaches. The paper also discusses some of the relationships between error identification and Ergonomics.
