Role tensions reflect a feeling experienced by a person in a situation where it is difficult to respond satisfactorily to all the expectations directed toward them. Drawing in particular on Kahn et al.’s (1964) role theory, researchers generally agree on three forms of role tension: role ambiguity, role overload (or work overload), and role conflict. Scientific studies show that role tensions are detrimental both to individuals (e.g., work stress) and to organizations (e.g., decreased job performance, withdrawal behaviors, etc.). Paradoxically, despite their dysfunctional effects, HR managers and supervisors pay little attention to the management of role tensions!

SCM (Supply Chain Management) covers all activities related to a company’s industrial macro-process. It thus encompasses all activities involved in the creation and production of the products marketed by the company (purchasing, procurement, production, order management, distribution, logistics). By using appropriate information systems, it manages not only physical flows (materials, components, finished products, etc.) but also information flows (orders, forecasts, inventory levels, lead times, etc.). Both intra- and inter-organizational, Supply Chain Management requires coordination among all internal (marketing, R&D, purchasing, sales, etc.) and external partners of the company.
