Systèmes d'Information et Management


This article aims to highlight the role of the context in the choice of communication means, through the examination of three sites of the same company. A case study was conducted in a car-manufacturing company. Data was mainly collected through interviews realized with 36 managers. Three forms of "millefeuille effect" were distinguished in this study. They can either be "constrained", "chosen" or "thought and emergent". We show that in the last case that both management involvement and the reengineering of coordination modes managed to improve working methods. We particularly notice the reduction of meetings number.
