Abstract
Outsourcing is considered by many as the major means to cost reduction and refocusing on core competencies. In that context, a worldwide Chemicals Group, studied in this research, aims at improving and piloting its intra-and inter company processes and at assuring the consistency of involved activities in the framework of important competitive pressure. The Group looks for realigning the activity portfolio and outsourcing activities, considered as not well-contained. Through a case study, we address how this international Group managed, through the reengineering of certain business processes (BPR), the dislocation of internal logistics activities outside the company, and the establishment of partnerships with external service providers.
