Comments

An Argument 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”). It allows the structure of the set of arguments to be created and agreed with an auditor/regulator/assurer before the detail of the Evidence required is added.

The Argument opposes Argument tuple allows counter or opposing arguments to be constructed (and then supported with relevant evidence).

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 an Argument within their metamodels.
