I am trying to model a certain Task element object that is performed by multiple players (swimlanes), the problem is I can’t expand the Task object to span across the multiple lanes. Is there a way to get this done? forexample: how can I model Task 1 to be shared or performed by swimlanes A, B and C?
The task cannot be located across multiple lanes. In fact, the task should be performed by specific role (the lane). For your case you have to create a new lane to model the role which will perform that common task.
One would use parallel paths (with Parallel Gateway, the diamond with the “+”) across lanes belonging to the same pool, with or without the exact same task. Each parallel path would then be joined after task is complete within each lane (again by using a Parallel Gateway).
