* Decomposition Diagrams of Business Functions
Prepare one or more decomposition diagram(s), each of which is headed by one of the business functions defined in the project scope. The business function may decompose into several lower-order functions or it may decompose into processes. It is possible that lower-order functions identified during EM are now recognized as processes, so they would be classified, redefined and renamed accordingly.
* Methods of Decomposition
The decomposition is achieved by a mixture of routes. For each function, consider what operational, control, planning and strategic processes will be needed to achieve the business objectives by the current strategies. Also consider what processes must exist in order to create each candidate entity type. At the same time, candidate processes identified in the earlier subtask List Candidate Entity Types and Processes need to be incorporated into the developing decomposition.
* Level of Decomposition
It is essential to subdivide each business function into a set of processes - two levels deep. Decompose the processes as far as the team's understanding extends, without going below the elementary process level. The result can be documented as an indented list or by a decomposition diagram. This decomposition diagram will be used to confirm the project's scope.
