Components Of Srs In Software Engineering

While the principles of modularity are widely applied in software design and development, their application to developing assurance cases from modular arguments is still immature. Modularity is often proposed as a mechanism to combat the growing complexity of system and software design and to promote reuse, thereby reducing development and maintenance costs. The identified challenges and potential solution proposals show how safety is related to Software Product Lines. An overview of similar research projects complements the analysis. We investigate which modularity concepts exist for dealing with safety, how variability concepts integrate safety, by which means process models can consider safety, and how safety cases are evolved while maintenance takes place. In addition, a detailed literature survey summarizes existing approaches. The semi-structured interviews identified the characteristics of current safety engineering processes, the handling of general variety and reuse, the approach followed for safety artifacts, and the need for improvement. In order to identify the challenges and possible solutions, we conducted interviews with industry partners from the domains of ICT, Rail, Automotive, and Industrial Automation, and from small- and medium-sized enterprises to large organizations. We investigate the possibilities of product lines with managed processes for reuse also across multiple domains.

Moreover this reuse is complicated, by the different situations in the various industries involved and by the corresponding standards applied.Ĭurrent industrial practice for certification processes relies on a component-based view of reuse. At present, however, it is still unclear how this reuse could take place. In order to do this economically, the safety artifacts of the components should also be reused. In the future, safety-critical industrial products will have to be maintained and variants will have to be produced.
