Develop GSN assurance cases

You can develop online modular GSN (Goal Structuring Notation) arguments using PREMIS assurance case tool. PREMIS supports Core GSN and partially Modular and Argument Pattern Extensions.

PREMIS argument metamodel is compliant with OMG SACM and ISO/IEC 15026.

Manage complex modular arguments

Break 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 higher-level argument modules. PREMIS implements three types of argument interfaces: away elements, supported by module and supported by contract.

Modules are also an effective tool for distributing work in teams
and organizations. For each module, you can assign individual user rights in PREMIS.

Integrate your arguments
with external evidence

The argument usually refers to the evidence produced in the system life cycle which is stored in repositories, usually in version control systems.

PREMIS provides out-of-the-box integration with SharePoint, Confluence and Jira Cloud. Integration with other types of repositories can be provided on request.

PREMIS monitors and reports changes of evidence in integrated repositories, enabling systematic change management.

Assurance case evidence management
Assurance case assessment

Perform reviews and assessments

  • Integrated argument assessment functions
  • Dedicated roles for reviewers and third-party assessors
  • Sharing comments to argument elements
  • Control of argument changes and the need for reassessment
  • Assessment methods include uncertainty, scoring and others
  • Automatic aggregation of assessment results
  • Reporting assessment results
  • Control of negative and missing assessments

Report on progress and results

  • Assessment visualisation with colour scale
  • Reports to MS Excel, Word, PDF and HTML
  • Custom report templates fed with XML data
    describing the argument and assessment results
  • Custom report content: GSN diagrams, assessment,
    charts, links to evidence
  • Programmable HTML reports using XSL scripts

collaborative assurance case development

Manage users rights

  • Role-based access control (RBAC) for all actions in PREMIS
  • Predefined roles such as manager, editor, auditor, viewer
  • Roles assigned at folder level
    or individual argumentation modules
  • Customisable user roles
    with over 40 permissions to specific actions

Reuse with templates

  • Create assurance cases based on templates
  • Use parameterised templates for variants of your system or products
  • Easily update arguments when a new version of a template is available
  • Use multiple layers of templates

assurance case change history

Track changes and use version control

PREMIS maintains a complete change history of all assurance cases. You can view any version of the argument since its creation. When necessary, you can restore or make a copy of any version of the argument.

PREMIS also checks if your reviews and assessments are up to date. The tool alerts you and points out the changes that you can review the modified parts of the argument again.


Make the argument dynamic
with live data input

As systems evolve, so must the assurance case. This can be achieved with a data feed that allows the assurance case to be updated. The PREMIS API interface allows other systems and software agents to connect and provide data that can be used to:

  • Update the evidence data
  • Modify argument structure
  • Deactivate or activate argument sections
  • Update the argument assessment

Best practices of assurance case development

Assurance cases are used in many domains to manage
and demonstrate system safety, security and compliance. The right understanding of the argument structure is essential for its effective use. The main goal of the course
is to provide skills to use proper and effective argument structures, develop defensible arguments, and review assurance case quality.

The training will help you improve the quality of your assurance cases.
