NOR-STA is a web application
for assurance case management
Develop arguments, don’t draw them
NOR-STA uses hierarchical assurance case notation which allows to develop argument structure in the editor without the need to draw it. When you need GSN diagrams you can generate them. The notation also complies with OMG SACM and ISO/IEC 15026.
Thanks to the notation you can easily manage large argument structures.
Divide and rule with argument modules
Divide large arguments into modules and manage them separately. Use interfaces to manage binding modules. The assessment will be automatically reported to high-level argument modules. When necessary assurance cases can share modules.
You can also use modules to manage work in teams. For each module you can individualy assign permissions for users. .
Integrate your argument with evidence
Repositories like SharePoint, Confluence, Jira or SVN can be integrated with NOR-STA. That makes easier the evidence management.
Evidence plays the key role in assurance. Your argument specifies what evidence is required, you review it to assess the argument and you have to react when the evidence changes. What’s more some evidence may become outdates. You should track evidence validity and react when it changes.
