International audience; Software Sharing in automotive embedded software development has continuously grown over the last decades and is still getting more importance and attention. Main advantages for Software Sharing, as seen by the OEM, are acceleration of development time and cycle as well as a full flexibility to customize the final product (with introduction of its own software).
