Picture what happens when you utilize the interstate at a 100 percent capacity. You have a traffic jam! In a traffic jam your speed goes down (sometimes you’re even standing still) and if you would measure the output at a certain point, you would find that the output goes down also. This is exactly what happened in our high mix/low volume job shop. At Kooima we created our own traffic jams by planning all machines as full as possible, resulting in long lead times, and a lot of work in process. Quick Response Manufacturing (QRM) teaches us that when you utilize capacity with more than 80 percent, your lead times will explode. PROPOS has proved QRM right.
