Determining the Sequence of Process Implementation

Ideally, the natural implementation sequence (see the Determining the Sequence for Business System Implementation section in this chapter) should be the sequence in which elementary processes are implemented within the first priority business system. This sequence can be determined from the order in which elementary processes are specified on the Dependency Diagram.

In many cases, the natural sequence is ambiguous because of mutually exclusive and parallel dependencies within the Process Dependency Diagram. You can sequence these ambiguous elementary processes by placing those with higher benefits first.

The implementation sequence of processes within a business system is subject to the same non-technical pressure for deviation as the implementation sequence for business systems themselves. As with business systems, you need to address and acknowledge the cost of introducing logical inconsistencies before finalizing the decision to deviate from the natural sequence.
