As an important type of architectural knowledge, documenting architectural assumptions (AAs) is critical to the success of projects. In this work, we proposed and validated an Architectural Assumption Documentation Framework (AADF), which is composed of four viewpoints (i.e., the Detail, Relationship, Tracing, and Evolution viewpoint), to document AAs in projects. One case study with two cases was...
Architectural Technical Debt has recently received the attention of the scientific community, as a suitable metaphor for describing sub-optimal architectural solutions having short-term benefits but causing a long-term negative impact. We study such phenomenon in the context of Volvo Car Group, where the development of modern cars includes complex systems with mechanical components, electronics and...
The automotive industry is currently going through an enormous change, transitioning from being pure hardware and mechanical companies to becoming more software focused. Currently, software development is embedded into a V-Model process that defines how software requirements are extracted from system requirements. In recent years, OEMs have come to recognize the importance and opportunities offered...
To investigate the new requirements and challenges of architecting often safety critical software in the automotive domain, we have performed two case studies on Volvo Car Group and Volvo Group Truck Technology. Our findings suggest that automotive software architects produce two different architectures (or views) of the same system. The first one is a high-level descriptive architecture, mainly documenting...
