Ergonomics in Brazil was initiated in the 1970s and at that time was infl uenced by Alain Wisner, which justifi es the fact that most ergonomics studies in Brazil follow the French approach of AET (in French Analyse Ergonomic du Travail). In the 1990s, another method proposed by Professors Anamaria de Moraes and Claudia Mont’Alvão gained strength mainly due to its clear framework for understanding and labeling of the many constraints which crop up in an ergonomics study. Despite the differences in the terms used, both AET (Guérin et al., 1991) and the systematic approach proposed by Moraes and Mont’Alvão (1998) are descriptive, in that they require a very detailed diagnosis, but they do not
necessarily lead to the application and further evaluation of work improvement. Also, both approaches are top-down, relying on the expertise of the ergonomics specialist, and not necessarily depending on the workers and managers to carry on the intervention.
