This paper introduces the ELICERE process: a dependability requirement elicitation process applied to critical computer systems, based on a goal‐oriented requirements engineering technique i* (pronounced i‐star ), and safety engineering techniques. After creating the system model using i* diagrams and their relationship components, such as goal, soft‐goal, resource and task, these components are analyzed through guidewords based on HAZOP and FMEA. This process is applied to some critical elements of the system model, from where goals related to dependability are extracted. The authors believe that this interdisciplinary approach will allow promoting the identification of goals that meet the quality requirements related to safety, reliability and other dependability factors still in the project conception phase. Also, ELICERE intends to facilitate the communication between system and software engineering communities, during a project requirements engineering phase.
