If the “True” value is assigned, the collaboration on the task workitems will be enabled. This implies that, when a user takes a task workitem, he will be able to choose a group of collaborating users. On doing this, all the collaborating users will be able to visualize the workitem in their respective inboxes and execute it, but only the user that took the workitem first will be able to complete it.
Notice that collaborating means creating a new workitem for each user involved in the collaboration. The user who started the task will be able to continue the flow when all the collaborators finish their own workitem associated to the collaboration.
