Functional safety measurement in the automotive domain: adaptation of PSM

In the safety domain, safety standards are used as development guidelines to keep the risk at an acceptable level. Safety of the safety-critical systems can be assessed according to those safety standards. This assessment process is called safety assurance. Due to the manual work, safety assurance process is usually costly, time consuming, and hard to be evaluated. In this paper we propose to use the existing PSM framework into the automotive domain to design metrics according to the ISO 26262 standard. These metrics can identify costly processes in the safety assurance process. To demonstrate the method, a case study is carried on ISO 26262 part 3 (Conceptual Phase).
