Design a flow to define:
The sequence of activities and processes.
The decision points and alternative paths in the process.
Which role is responsible for which part of the flow.
Each flow is related to a process. The process type defines the flow design options:
Process: You can design a process flow with activities, lanes, sub-processes, gateways, events, and connect these objects in the sequence to be done.
Value chain, Phase, Process group, Supporting process: Additional to the design of a Process type flow, you can add business processes from the hierarchy to the flow design.
Notes
This flow represents the usual sequence in which the process flows are designed. If required, you can of course design the flow in another sequence.
