Master Architecture View

Any Claim used within an architecture description of the system-of-interest must appear on a MV-04 Assurance View for the architecture description.

The MV-04 is the Master Architecture View for Claim.

Covered by TRAK IPR and licenses


A Claim is a fundamental part of the Claim - Argument - Evidence (CAE) structure used in describing the structure of an assurance case such as that used for safety assurance (or a safety case as it used to be called in “old money”). TRAK provides the ability to make a claim about any element in any of the TRAK Perspectives (Claim about ...) linking the assurance case to the architecture description. The Argument element allows a feature represented in the architecture description to be used as the basis for part of the supporting / opposing argument.

Other Frameworks

Neither MODAF nor the NATO Architecture Framework are able to represent a Claim within their metamodels.
