ABSTRACT
To be an ergonomist in an engineering design environment may be assumed in many ways. Traditionally, ergonomists have been asked for inputs at the final stage of design processes to help designers fix some details to ensure that the final product will fit the human being. More recently, with new methods in engineering new ways of intervention are developing. Moreover, ergonomic interventions now cover many domains in the design field: technical devices, either hardware or software, work organization and training. Ergonomists are now being asked to participate in teams designing whole plants. A model of ergonomic interventions that defines the ergonomist as an effective player in the design process is presented here.
