Abstract: Based on the methods of Cook and Campbell (1979), a quasi-experimental validation model for complex human–machine systems has been recommended for the final evaluation of nuclear power plant control rooms (O|Hara et al., 1997). This model-based approach to validating systems and assuring safety is critiqued in terms of experimental theory and engineering practice. It is concluded that the model may be inappropriate for industry as a general model of engineering validation.
