ISDABS Stage 3: Justification Alignment


STEP 4: Extend Justification Alignment Contour(s)


The Justification Alignment Contour is extended for each system by considering the information requirements, that is, the information needed about the key items included in the Justification Alignment Contour in order to fulfil the requirements of the system. This may lead to the identification of further items for inclusion on the model.

The Justification Alignment Contour is first stripped of all elements except those about which information is needed in order for the system to operate. Each item is then illustrated by a circle and information (e.g. attributes) concerning the item are added around the circle. This forms the first part of the Extended Justification Alignment Contour.
