Queues form when work items that have been started just get stuck somewhere in your process (without completing). Items may get stuck because: - There are no more resources available to continue working on them. - Some manager mandates that more new work be started before current work has finished. - Resources that are actually doing the work are constantly pulled in multiple different directions and are not allowed to focus on any one thing. - There is a dependency on some external team or vendor.

As we move from 60-80% utilization, the queue doubles. As we move from 80-90% utilization, the queue doubles again. And again from 90-95%.3 Once we get past 80% utilization, the queue size begins to increase almost exponentially, slowing things down to a grinding halt as it pushes 100% capacity utilization.
