Expérimentation d’une évolution méthodologique du dispositif d’innovation transitionnelle et approfondissement du passage aux transformations : retour sur une recherche-action dans le secteur médicosocial

In the current socioeconomic context, companies are called more than ever to transform themselves for more social and economic performance. Various attempts are made, sometimes promoting health or damaging it. The psychology of work also seeks to think of theoretical and methodological models to support this work of alliances between social and economic performance and questions in particular a psycho-socio-organizational approach to management. In view of these challenges, this article presents an action-research conducted within a service of the medico-social sector struggling with major conflicts and whose actors wanted rapid transformations. This context was the opportunity to test the transitional innovation mechanism developed by Guidou and Sarnin (2021) to support transformations even in a degraded situation. However, an evolution has been proposed to shorten its duration. After presenting the situation, we explain how we accompanied this collective of 22 professionals. We show how the device promotes the emergence and development of transitional activities that generate creativity and innovation, making it possible to overcome the difficulty of going from diagnosis to transformation. We particularly question the transformations taking place within the activity system and try to deduce relevant indicators to observe the transitional innovation process.
