 From Sen to Ergonomic Practices: the Conditions and Means for an Enabling Organizational Intervention 
This article addresses the means and conditions of an enabling organizational intervention using and developing Amartya Sen’s conceptual framework. Specific attention is devoted to the conceptual foundations underlying the proposed methodology. The methodology was developed in a research-intervention aiming to (re)design the organization of a medical process. The development of both collective agency and capabilities was a fundamental aspect of the intervention. The methodology is grounded in the desire to understand human activities and seeks to contribute to the development of the individual, team, organization, and activity. In this constructive framework, the ergonomist acted as a conversion factor, transforming individual and collective capacities into the ability to actually “perform better together.” Individuals became agents capable of designing their own future activities. The conclusion addresses, on one hand, the conditions for generalizing the proposed methodology and, on the other hand, the roles of the ergonomist in an enabling intervention.
