Initial process requirements are identified by analysing the relationships between the elements (represented by the circles) of the Extended Justification Alignment Contour (EJAC). This analysis highlights the main business rules which must be supported by processing. Consideration must then be given to how the elements of the Extended Justification Alignment Contour are created, modified and deleted. Individual data items are then examined to identify any associated processes. A data flow diagram may be created to outline the flow of data through the system, to identify any omissions or inconsistencies.
