Can a task go to two other paralell tasks?

[kethur]

Hi All,

If i have a workflow process like below, which one actually works after the which one.  Because, usual workflow should be usertask1 leads to usertask2 but, in this case usertask1 leading to usertask2 and usertask3.  Will both the tasks be executed simultaneously?  I thought for this kind of scenario you use parallel gateway.

  <process id="process1" name="process1">
    <startEvent id="startevent1" name="Start"></startEvent>
    <userTask id="usertask1" name="User Task"></userTask>
    <sequenceFlow id="flow1" name="" sourceRef="startevent1" targetRef="usertask1"></sequenceFlow>
    <userTask id="usertask2" name="User Task"></userTask>
    <sequenceFlow id="flow2" name="" sourceRef="usertask1" targetRef="usertask2"></sequenceFlow>
    <userTask id="usertask3" name="User Task"></userTask>
    <sequenceFlow id="flow3" name="" sourceRef="usertask1" targetRef="usertask3"></sequenceFlow>
  </process>

I appreciate your help!

Thanks,

When usertaks1 is completed, it will take all outgoing flows. So indeed, usertaks2 and usertask3 will be available in the task-list, as out user guide describes:

A sequence flow is the connector between two elements of a process. After an element is visited during process execution, all outgoing sequence flow will be followed. This means that the default nature of BPMN 2.0 is to be parallel: two outgoing sequence flow will create two separate, parallel paths of execution.

But for readability purposes, it's better to use a parallel-gateway for this…

Many thanks for the quick response.
