Tell me how you measure me, and I will tell you how I will behave

An hour saved at the non-bottleneck is a mirage.

The goal is not to improve one measurement in isolation. The goal is to reduce operational expenses AND reduce inventories and increase throughput simultaneously.

If you don't manufacture a quality product all you've got at the end is a bunch of expensive mistakes.

If we reduce batch sizes by half, we also reduce by half the time it will take to process a batch. That means we reduce queue and wait by half as well. Reduce those by half, and we reduce by about half the total time parts spend in the plant. Reduce the time parts spend in the plant and our total lead time condenses. And with faster turn-around on orders, customers get their orders faster.

Never let something important become urgent

Make the bottlenecks work only on what will contribute to throughput today … not nine months from now. That’s one way to increase capacity at the bottlenecks. The other way you increase bottleneck capacity is to take some of the load off the bottlenecks and give it to non-bottlenecks.
