With certain privileges enabled, participants may also be able select a work item from their allocated queue and enact one of the following actions: Delegate to another: If the combination of participant and work item has the Can Delegate privilege enabled, the participant may chose some other participant to delegate the work item to. The effect of this will be to move a work item from the allocated queue of this participant to the allocated queue of the delegate. Note that only those participants that may be validly offered this work item (i.e., those listed in the distribution set of the work item’m task) will be offered as possible delegates. The petri-net transition for this is named route delegation in figure 51 of the newYAWL technical report. Deallocate themselves: If the combination of participant and work item has the Can Deallocate privilege enabled, the participant may chose to deallocate themselves from the work item. The effect of this will Page 91 of 100

Figure B.5: A possible offered queue implementation interface be to remove the work item from this queue, and place it on the unallocated queue of the administrator management intervention screen discussed earlier. The petri-net transition for this is process deallocation in figure 52 of the newYAWL technical report. Reorder work item: If the participant has the Can Reorder Work Items privilege set, the participant will be allowed to select a work item in the allocated queue and move that work item up or down in their work queue. Work items closer to the top of the queue are expected to be started before work items further down in the queue, which is especially true when the Can Choose Work Item to Start privilege is disabled for the combination of participant and work item. Skip a work item: if the combination of participant and work item has the Can Skip runtime privilege enabled, they will be allowed to select a work item from the allocated queue and skip it, automatically completing that work item, using default values of data that the work item must output to subsequent work in the case. Toggle view all work items: If the participant has the Can View All Allocated Work Items privilege set, the participant will be supplied a toggling mechanism, allowing them to view (but not otherwise manipulate) all other allocated work items in the entire system. So as not to interfere with their own allocated work items, these other allocated work items will appear in a visually distinct queue on the same screen as the participant’s own allocated work items. An indicative screenshot of this requirement is supplied in figure B.6. This requirement is classified as core . However, most of the actions listed that are driven off privileges are Page 92 of 100

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
