Developmental foundations of Activity-Centered Ergonomics: knowledge encounters to construct both a critical analysis of work and developmental set-ups

This paper presents the developmental foundation of Activity-Centered Ergonomics (ACE) that has been shaped by both: (1) a critique of conceptions of work and of its organisation in relation to economic and political models of development, and (2) developmental approaches to understand and to act on activity and work situations at different levels (individual, collective, organisational, and territorial). To do so, we examine some key reference works for ACE over 75 years with regards to these two dimensions and the methods and developmental set ups proposed. We argue that ACE analytical and transformative goals give a considerable space to knowledge encounters and workers' activity. We conclude by briefly discussing some of the current ACE works seeking to expand research-action over time and level of action (geographical area and public policies), in order to address key societal issues, including sustainable work and development.
