ABSTRACT
Although our accounts have brought to light the many singular aspects of conducting a human factors assessment, our analyses have allowed us to clarify certain consistencies in the specialists’ practices and regulation methods characteristic of the control system that frame their activity. These are the existence of a reference model of organization, the use of two types of analysis (comparison with the reference model and causal analysis), the use of two models of knowledge production (field, involvement) and the practice of two forms of regulation (based on compliance and deterrence, respectively).
