piling up at the bottleneck.” Resource Utilization “The wait time is the ‘percentage of time busy’ divided by the ‘percentage of time idle.’ In other words, if a resource is fifty percent busy, then if a resource is ninety percent busy, the wait time is ‘ninety percent divided by ten percent’, or nine hours. In other words, our task would wait in queue nine times longer than if the resource were
