Les dispositifs de discussion sur le travail : conception pour l’usage, conception dans l’usage

Abstract : This research deals with “Work Discussion Spaces”. Work Discussion Spaces (WDSs) are currently developed, both in practice and in theory. This thesis further reflects upon the design of these spaces, the methodology of their implementation, their conditions of use and their sustainability over time. It also examines their implications for management, participation and decision-making.The thesis builds upon the constructive ergonomics approach, aiming to open it to the management approach. The aspiration of constructive ergonomics is to develop “enabling organizations”, that is to say organizations which are able to develop themselves by creating a space for work discussions, thus permitting the growth of both the individual and the collectives. Management science develops the idea of a governance model “open to discussion” at every level of the hierarchy, thus permitting subsidiarity (i.e. decision-making at the lowest relevant level of the hierarchy). This thesis then defends the idea that enabling a sustainable debate in the workplace requires to apprehend Work Discussion Spaces in the light of activity issues, following bottom-up dynamics, while promoting institutional support for the discussion, with a more top-down logic.To that end, four situations of use of Work Discussion Spaces were studied in two social protection organizations, in a bank institute and at “La Poste”. The Work Discussion Spaces that were implemented were considered as “artifacts”, designed for use by designers and adapted in use by its users. In order to identify the various forms given to and taken by them, their evolution was studied following two different temporal scales: from one company to the other, and within two companies.Results show that, according to situations, Work Discussion Spaces were accommodated in different ways, emphasizing the importance of adapting modalities of discussion to local specificities. WDSs enabled regulation of work situations and have challenged some traditionally top-down managerial cultures, initiating an evolution towards a more participatory and subsidiary management style. In order to guarantee their sustainability, the Work Discussion Spaces need both to organize the “discussion space”, in particular by organizing subsidiarity, and to rely on an intervention that takes into account the specificity of each activity, following a participatory and voluntarist design approach.
