ASCE™ - What is a Safety Case?

Modern safety regulation require safety cases to be developed and maintained as a primary means of communicating the safety requirements, safety management environment and supporting evidence for the safety claims about the system.

Safety cases are explicitly required by licensing regulations in a wide range of industries and equivalent requirements are given in many standards such as IEC 61508. We define a safety case as:

A documented body of evidence that provides a demonstrable and valid argument that a system is adequately safe for a given application and environment over its lifetime.
