Manufacturers today operate in heterogeneous PLM environments, often built over the years around legacy PLM solutions, proprietary systems, custom developments, and specialised business tools. While these ecosystems have met specific needs, they are now reaching their limits in the face of increasing product complexity, expanded collaboration between partners, and heightened demands for traceability, compliance, and performance. Migrating to Dassault Systèmes solutions and the 3DEXPERIENCE platform is therefore becoming a strategic lever for unifying master data, securing critical data, and supporting business process transformation, all while avoiding any operational disruption.
