I am a facilitator for our circle of IT infrastructure people. I let anyone add an item to triage at any time, the clock is a moving target. If someone has 10 items and only 15 minutes left, I'll ask them to pick the most important item and make it brief. If they start to ramble I ask, "What do you need" or "What action do you require". I'll then move to another person in the group to process their item. Everyone gets a turn, all items may not be covered in the allotted time but the important issues are addressed. As we have progressed in our practice, people come prepared with short concise items that can be addresses quickly.
