## Abstract

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.
