Single Action Gateway

Question

I would like to design a BPMN flow where there is only one single action the user can decide. Meaning, in an exclusive gateway there is only one path, say "Done". In business point of view, the flow will wait for a User Task. When the User finished it task, he/she will say "Done". The user have no other actions (This is not a yes/no situation).

So, can I have an exclusive gateway with one condition expression?

Thanks in advance!

Answer 1

Since a user task is blocking, it will only move forward if the user marks it as completed. So you don't need a gateway after it.

Answer 2

A (BPMN) gateway is not a decision point, as in typical flowcharting. Instead it splits/joins the flow by evaluating existing facts established in preceding activities.
