The automotive industry gained momentum and expanded in recent years thanks to the expansion of novel features. An important factor for the introduction of safety and leisure features inside modern cars is the increasing use of software, especially manifested by a rise in artificial intelligence and machine learning. Even though the industry has been mandated by rigid safety processes, the need to innovate forces vehicle manufacturers to consider suppliers with non-automotive mature products. The challenge is further exacerbated by the fact that software is mostly developed in an agile fashion. A fine balance between safety, as a paramount factor, and the need to innovate, as a pressing factor, poses a challenge when integrating and developing modern car software. The scientific paper examines the state-of-the-art literature that enables marrying the best of both worlds: strict and rigid safety development life cycles and flexibility and reactivity of agile methods – an overview of the ISaPro framework model and Safe Scrum is given in detail. Furthermore, the scientific paper focuses on examining the necessary steps and methods needed to not only progressively transition the mature non-automotive software to the safety realm but to go a step further. The scientific paper examines how to capture more generic assumptions and the context to prepare the software product to serve as a generic SEooC for future automotive tenders. The scientific paper argues that it is a worthwhile endeavor to use the momentum of an ongoing project to gain safety expertise and prepare for future tenders. An essential part of the transition is a practical and formal approach to the Safety Contracts that further supports continuous updates to the safety case needed for assessment and certification. The scientific paper presents a use-case involving three-tier organization structure: classical OEM and Tier 1, and Agile Software as a basis for tailoring of an integrated ISaPro framework model to include the modified agile practices (parts of Safe Scrum and Safety Contracts processes) which focuses on reaping the benefits from both worlds. The scientific paper concludes by summarizing the benefits of the proposed approach. The scientific paper offers an initial step that could be further improved and fine-tuned through practical application in real projects to make it more robust and applicable in more diverse use case scenarios and to validate the assumed benefits especially in terms of financial benefits.
