Parallel Actions

When two actions happen at the very same time, you can make use of parallel actions. In your diagram, you first need to fork the flow. This is done with a thick black bar. Then, once the parallel actions have ceased, you merge your flow again with a similar bar.

“Concurrent action A” and “Concurrent action B” happen at the same time. Only once they are done, will the activity flow merge and continue with the “Next action”.

You might not actually use this (you probably won’t), so I’m not going to bother really go into too much detail. Maybe for the next edition of this guide.
