Abstract
Safety can be defined as a state in which the level of risk is acceptable for the user. The risk is an expression of the possibility of a mishap in terms of hazard severity and hazard probability. The aim of constructing safety is to prove that the system possesses the highest safety integrity level. The Safety Case forms the main proof that the system complies with the safety requirements. This paper gives an assessor point of view for the Safety Case structure and role. It presents the main properties that a Safety Case must have.
This paper reflects work which is partially funded by the CEC under the ESPRIT III programme in the area of Information Processing Systems, Project number 9032:” Certification and Assessment of Safety-Critical Application Development.
