A Conceptual Framework of Collective Activity in Constructive Ergonomics

The aim of this presentation is to present a constructive view of the development of collective activity. The concept of collective activity is a proposal of Caroly [1] aiming to connect cooperative work of operators with work collective - collectif de travail in French - that they belong to. These tow concepts are described to understand the organizational conditions to support the development of collective activity: recognition of skills, arenas for debate of criteria for quality of work, reelaboration of rules, intermediaries objects, technical systems, projects design, reorganization with managers.
