I think I can provide you with a good example. For instance, on Weekly Staff meeting team usually reviews its metrics. One of the metrics we review is a Queue Length(number of tickets at a specific stage). From the dashboard, we see that InProgress queue is growing the second week in a row. In this case, we start a fruit-full discussion on how to reduce it. If we can't find an answer on the meeting we should continue on Adhoc Topical meeting. For this meeting, we can assign a couple of people to dig deep in the topic and prepare some data and solutions for Adhoc Topical. Does it make sense to you?
