An Approach to Maintaining Safety Case Evidence After A System Change

Publication Type:

Conference/Workshop Paper


2014 Tenth European Dependable Computing Conference




Developers of some safety critical systems construct a safety case. Developers changing a system during development or after release must analyse the change's impact on the safety case. Evidence might be invalidated by changes to the system design, operation, or environmental context. Assumptions valid in one context might be invalid elsewhere. The impact of change might not be obvious. This paper proposes a method to facilitate safety case maintenance by highlighting the impact of changes.
