Toward Integrating a System Theoretic Safety Analysis in an Agile Development Process

Abstract: Agile development methodologies are becoming a tendency in today’s changing software development. However, due to a lack of safety assurance activities, especially safety analysis, agile methods are criticized for being inadequate for the development of safe software. In this paper, we introduce an agile ”Safe Scrum” by mapping a novel systematic safety analysis method, called STPA (System-Theoretic Process Analysis) into an existing agile development process ”Safe Scrum” for safetycritical systems. This work is done by (1) performing safety-guided design inside each sprint, and (2) replacing the traditional RAMS (Reliability, Availability, Maintenance, and Safety) validation. We aim to extend Safe Scrum by integrating STPA, to find a balance point between Safe Scrum and basic Scrum.
