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

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.

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

So this is the goal: To make money by increasing net profit, while simultaneously increasing return on investment, and simultaneously increasing cash flow.
