Initial Results

Context: traditional hazard analysis techniques were not proposed to be used in the Requirements Engineering (RE) process. Objective: The aim of this work is to present and discuss a new method for early safety requirements specification called SARSSi* to be used at the beginning of the development of safety-critical systems. Method: this goal is achieved through the combination of two techniques: (1) STAMP/STPA; and (2) i* language. Results: this paper attempts to bridge the gap between two parallel trends in systematic safety approaches – the combination of requirements and safety engineering techniques. Our method consists of six steps and guidelines to perform a preliminary hazard analysis and facilitate the systematic identification of safety-critical functions and components. Conclusions: We demonstrate the utility of our method by applying it in a real industry case study. The initial results show preliminary suitability of our method and its contribution to improving the visualization of the information generated in the hazard analysis such as the hazards, their causes, environmental conditions, and safety requirements.
