  This paper presents a SysML-based approach to enhance functional and software
development process within an industrial context. The recent changes in
technology such as electromobility and increased automation in heavy
construction machinery lead to increased complexity for embedded software.
Hence there emerges a need for new development methodologies to address
flexible functional development, enhance communication among development teams,
and maintain traceability from design concepts to software artefacts. The
discussed approach has experimented in the context of developing a new
transmission system (partially electrified) and its functionality. While the
modeling approach is a work-in-progress, some initial success, as well as
existing gaps pointing to future works are highlighted.
