Process Fragments
Predefined fragments are provided in the folder Business Process Fragments.
For example, Basic Fragments contains simple fragments such as an embedded sub-process, split conditional, and task sequence.
Rather than reusing an entire process, you can use the Fragments view to quickly create new processes.
You can also create your own process fragments. For example, there might be process patterns that you frequently use. By storing these patterns or "fragments" you can easily use them to construct new processes.
Custom Fragments
The Fragments that you create are stored in the category you specify and can be used to create new processes in the same way as predefined fragments.
