The development of vehicles is a multifaceted endeavor that demands a well-organized strategy to ensure effectiveness & efficiency. This paper emphasizes crucial aspects that support engineering teams in executing systems engineering tasks, especially when dealing with complex systems or large-scale projects. It contrasts the traditional system-based approach with the feature-based method that will become relevant for software-defined vehicles. By focusing on a comprehensive management of features, the feature-based approach facilitates improved coordination, reduced development time, lower costs & enhanced customer satisfaction. Moreover, the paper outlines reliable & established techniques for crafting safety strategies, generating requirements with sentence templates & conducting test automation. It also introduces AVL ComplyGuard™, a tool that plays a pivotal role in the successful application of the proposed efficiency boosters.
