How to Construct Process Models
The Event-Decomposition Diagram
- The purpose of this step is to further partition our functions in the decomposition diagram.
- Simply add event handling processes (one per event) to the decomposition.
- If the entire decomposition diagram will not fit on a single page, add separate pages for subsystems or functions.
- The root process on a subsequent page should be duplicated from an earlier page to provide a cross reference.
