Over time, Drivindus has become one of the world’s leading manufacturers of automotive parts. This industrial group is present in 20 countries, employing 50,000 persons from 50 different nationalities and running around 100 factories and 40 research centers. It generates annual revenues of nearly €10 billion. The firm’s General Management has noticed that productivity reserves still exist within its purchasing management function. The company has therefore decided to invest in an e-sourcing project. This case study describes this project which has been inspired from a real one and shows how an electronic marketplace has been designed to reach all the objectives. This case study takes between 4 and 6 hours to be solved by post graduate management students. They may be organized in groups of 4 and the instructor can go from one group to another to help them progress, according to their capacities, in answering the 5 questions. A PowerPoint presentation and teaching notes are provided to help in the animation of the case which has been tested and optimized in three different accredited management schools before its publication. It’s ideal to illustrate purchasing management evolution and information systems management.
