Chapter 5 Building a Process Hierarchy Diagram

Why Build a Process Hierarchy Diagram?

You build a process hierarchy diagram to identify the atomic business tasks, review the whole process of a business project and focus on redundant or missing tasks.

The process hierarchy diagram allows you to:

Define all the processes performed in the scope of a business function, independently of their execution order or conditions
Focus on process recognition and enumeration, only process names are defined at this step
Decompose already identified processes into sub-processes until a satisfying atomic level is reached
Reorganize sub-processes by changing their parent
Display in a single view the whole hierarchy of an already described process or of any composite sub-process
