GSN Patterns

The intent of this pattern is to provide a top level decomposition for the safety argument of a system. In particular, the pattern provides the context for a software safety argument constructed from the Software Safety Pattern Catalogue. The focus for the argument is the identification of hazards and the assessment of the associated risks.

This pattern identifies the three main claims which must be satisfied to show system safety; Valid Safety Requirements, Acceptable Levels of Risks, and Traceability of Safety  requirements and Safety Evidence. The pattern provides a suitable context and approach for developing a software safety argument.
