Traditional design processes must adapt to new industrial challenges, to the rapid evolution of technologies and the resulting complexity of systems. Today's industry, particularly in the field of mechatronics, must design and develop ever more innovative products while reducing time-to-market in order to maintain a competitive edge. As late changes during the realization and detailed design phases lead to a considerable increase in costs and design time, it is necessary to introduce more flexibility during the development process. The agile approach has already proven successful in the design of software system and offer many benefits, as it aims to limit the rigidity of the specifications, interfaces and organization, and to involve in a more flexible way the different actors, customers, specifiers and partners. In this context, we propose a MBSE approach to identify the set of requirements related both to the mechatronic product development and to the dynamic market, companies and current new trends, in order to define the SCRUM++ framework key concepts that aim to meet previous requirements, by supporting agile hybridization methods.
