2.1.1 The Submarine Assurance Framework comprises a hierarchical set of Goal
based requirements to be satisfied in the design, construction or maintenance of a
submarine as relevant, supported by planning and verification processes by which LR
will provide independent assurance that those requirements have been satisfied.
2.1.2 The Goal based requirements of the framework are consistent with those of
the NSubC, however unlike the NSubC, the framework also defines the planning and
verification processes which may be used to demonstrate that the Goal based
requirements of the framework have been satisfied.
2.1.3 Consistency between the Goal based requirements of the framework and the
Goal based requirements of the NSubC allows compliance with the NSubC to be readily
demonstrated.
