Taichi Ohno says “All we are doing is looking at the timeline from the moment the customer gives us an order to the point at which we collect the cash. And we are reducing the timeline by reducing the non-value-adding wastes.”
Boart Longyear did exactly this: within four months, the company cut its lead time from 138 days to 12 days by using this workbook, rethinking its supply chain starting at the customer and working backwards, and systematically eliminating waste and inventory from the process so that only value remained.
“At LEI we have long felt the need to remedy instability in information and order flow to create smoothly flowing streams of products from suppliers to customers.
