Assurance Case Patterns On-line Catalogue
- First Online:
Assurance case is an evidence-based argument demonstrating that a given property of a system (e.g. safety, security) is assured. Assurance cases are developed for high integrity systems, as in many industry domains such argument is explicitly required by regulations. Despite the fact that each assurance case is unique, several reusable argument patterns have been identified and published. This paper reports work on development of an on-line assurance case patterns catalogue available in NOR-STA web-based software tool. This work included an extensive literature search, critical evaluation of available patterns and selection of most relevant ones, finally translation of selected patterns to their target representation. The paper also describes a validation case study in which an assurance case for medical devices was reviewed and restructured by introducing patterns. The resulting catalogue was published and its 45 patterns can be directly used in assurance cases built using NOR-STA tool.
