Combining qualitative and quantitative data : a powerful lever for driving an organizational change process

Abstract : For a long time the management sciences had conflicting viewpoints on intervention methodologies, essentially qualitative and quantitative data. From the consultant's point of view this dichotomy seems sterile because beyond the quality of the collected information, their action is often assessed on the quality of this implementation in the process. This communication focuses on the collection of combined qualitative and quantitative data as well as their treatment in an intervention context in vivo related to the organizational change process. The main issue is to underline the virtues of the qualitative / quantitative mixing in a process of change, by highlighting at the same time its impacts on the dynamics of the intervention and on the significance of the information collected to assure the mission both for the internal actors and for the third parties.
