The Supply Chain Management systems are widespread in all kind of industry to organize the flux into each step of the value chain. The digitalization and the rapid evolution of the SCM have forced the enterprises to adapt their architectures and their physical structures to follow the continuous updating of these systems. The aim of this work is the analysis of the implementation of a new warehouse management system (SAP EWM) in an industrial reality: the Volkswagen Spare Parts Distribution Center in Verona. The focus of the project, based on my internship experience in Volkswagen Group Italia, is on the fulfillment of the Preparation Phase of the whole program that will end with the go live and the stabilization of EWM.
