Simple Merge

Here is a BPMN diagram example that shows the use of the pattern Simple Merge.

• When several exclusive conditional paths converges on a single activity, which starts when one chosen path completes.
• XOR-join
• Is the endpoint of a process split started by an exclusive choice.

The power of patterns in a process becomes clearer when one pattern combines with others to form processes. Simple Merge is one of the many examples of this. Anytime an Exclusive Choice pattern occurs, somewhere downstream in the process there will almost always be a Simple Merge pattern. Simple Merge combines several transitions back into a single activity.

As shown in Example, the "Close Claim" activity merges the transitions coming into it. The insurance claim instance coming into it came from only one of the activities upstream in the process.
