To efficiently manage a large process landscape, it can be broken down into modules. These modules can be connected via interfaces. Process modules can form a hierarchy or process architecture.

Typical process modules are Requirements Engineering, Design, or Project Management. As process modules can be used to separate common from specific processes, a “Design” process module could be used to contain the common elements in a “Engine Design” and “Transmission Design” process module. See process variant management for more info.

The only difference between a process and a process module is that a process module can be added to other processes or process modules, whereas a process can not be added anywhere else.

- Normal process

- Process type → Process module

- Create version and mark it valid

- Add into existing process

- Create new workspace

- Select “Add Modules”

- Spot the outdated modules

- Update them one by one or multiple in sequence

- Remote associations

- Become normal associations when both modules are added to one process
