Develop GSN assurance cases
The Goal Structuring Notation (GSN) is the most popular graphical notation for assurance cases. In NOR-STA you can develop GSN assurance cases and generate argument and architecture view diagrams. NOR-STA implements Core GSN
and partially Modular and Argument Pattern Extensions.
NOR-STA argument metamodel is compliant with OMG SACM and ISO/IEC 15026.
Manage complex modular arguments
Divide large arguments into modules and manage them separately. Argument modules can be bound with interfaces
and the assessment of supporting modules will be automatically reported to high-level argument modules.
Modules are also an effective tool to distribute work in teams
and organizations. For each module you can individually assign permissions for users.
Integrate your arguments
The argument needs to refer to evidence produced in the system life cycle which is stored in some repositories, usually in version control systems.
NOR-STA provides ready to use integration with SharePoint, Confluence and Jira. Integration with other types of repositories can be provided on request.
NOR-STA monitors changes of evidence in integrated repositories, reports them and enables systematic change management.
Reporting progress and results
Users and permissions management
Reuse with templates
Change tracking and version control
System assurance monitoringAssurance case may be fed with live data from any evidence management system or production system monitoring. Data can be automatically transferred into an argument and can be used to:
Integration with other systems
Step by step Assurance Case Training with NOR-STA
November 30 – December 2, 2022.
Master assurance cases in 3 half-day training sessions:
Day 1: Learn the argument structure and how
to develop assurance cases in NOR-STA
Day 2: What is a good argument, how to make
the assessment and report the results.
Day 3: How to develop modular assurance cases
and use argument templates.
Hands-on exercises in NOR-STA during all training sessions. The training will give you practical skills to develop and manage advanced assurance cases.
