NOR-STA is a web application
for assurance case management
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 Extension and Argument Pattern Extension.
NOR-STA argument metamodel complies 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 with evidence
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.

System assurance monitoring
Assurance 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:
