Nowadays the automotive industry is challenged in several areas such as, advancements in technologies, change in customer behavior, strict regulation and narrow competition. On one hand the focus is to be competitive on the market by embracing the trend of “EACSY” (Electrified, Autonomous, Connected, Shared and Yearly updated) vehicles. On the other hand, processes optimization and reengineering should not be neglected. Among them, the warranty management is a key asset for automakers to decrease wastes and improve the efficiency of the related activities of the value chain, such as design, production, marketing and after sales. In this context fits the “Warranty 4.0”, strategic project of a multinational vehicle manufacturing company, realized by the consulting company hosting the internship and thesis work.
