Examine the summary timeline and portals for the value stream. Notice if there is a huge difference between portal lead time and portal processing time. Compare the throughput rate to the tack, or customer demand rate. Is the end-to-end process producing fast enough to keep up with demand? How good is the quality of the end-to-end process? In other words, what is the raw throughput yield, or RTY, of the value stream? With this understanding of the big picture, you can then drill down to identify the culprits of poor performance, the processes or major process steps with long lead times and high defect or rework rates, and determine if there are any glaring wait times or high WIP, or work in process inventory, between major process steps. If necessary, conduct workload and cycle time analysis against tack…
