Although digitization might be considered a driving factor behind Procurement 4.0 it is far too shortsighted to limit Procurement 4.0 solely on tools and automatization. Indeed, no clear vision has yet been developed describing the full meaning and impact of it. In Procurement 4.0, five leading experts provide further insights on how to best face the current and upcoming challenges. Four dimensions of procurement that will address the business needs of the future are further explored: competing value chains, co-creation, leadership and network enablers. Dynamic, interconnected value chains are key factors of sustainable business success, with procurement managed and steered by strategic purchasers in their new role as value chain managers. This evolving environment will be influenced and supported by a variety of digitization elements, internet of things, smart data and mobile computing - to name a few. To gain a clearer picture of future procurement, the authors conducted interviews with leading procurement heads of global corporates such as BMW, Lufthansa, Maersk, BP and Allianz. These industry insights combined with various other cases offer a practical view to shed light on this still rather theoretical construct.
