The report is the result of the candidate's working experience at the company Marelli Europe S.p.a. located in Venaria Reale (TO), within the "Electric Powertrain" Business Unit. Since continuous improvement is one of the basic aspects on which every Quality Management System is based, the candidate focuses on the Lessons Learned management system. Historically, in M-EPT the LL management system is provided exclusively for the “product development” and “series production” processes. Consequently, the candidate's goal is to improve and to extend the current approach used by M-EPT to the other QMS processes, implementing a unique methodology that considers not only the technical aspects but also the systemic / managerial ones.
