If you need a process, flow, or activity, first search if it already exists in the current or a referenced solution. If the required flow, or activity:

• Exists and exactly reflects what you need, use it.
• Exists (in a referenced solution), but changes to it are required for your solution: copy it and make it solution-specific.
• Does not exist: create a new process, flow, or activity.

Note:

• You are only allowed to change an existing flow, or activity if it is owned by your solution!
• It can be that the flow or activity exists in your solution, but you are not the owner of it. In this case, first discuss with the current owner before you make the changes.
