No Software-Defined Product Without MBSE

Software-defined products like SDVs hit their limits fast without sound systems engineering. Why a continuous Digital Thread across the whole lifecycle is key.

Without sound systems engineering and the methodology of model-based systems engineering (MBSE), the development of software-defined products (SDP) — such as software-defined vehicles (SDV) — quickly reaches its limits.

Variant diversity, technical complexity and the growing number of over-the-air updates challenge the automotive industry — and at the same time are a wake-up call for every industry: Is your own PLM strategy still up to date if the product lifecycle ends at the factory gate?

The future belongs to products that stay updatable throughout their entire lifecycle. That takes a continuous Digital Thread that closes the gap between requirements, production and ongoing development.

The PROSTEP Group and BHC GmbH support companies in exactly this: getting PLM, ALM and MBSE processes ready for software-defined product worlds — from strategic concept to successful implementation.

Takeaway

Software-defined products need more than new software features — they need a systems engineering foundation that covers the entire lifecycle. MBSE and a continuous Digital Thread are not optional extras here, but the basic prerequisite.
