Costs do not exist to be calculated. Costs exist to be reduced.

The key to the Toyota Way and what makes Toyota stand out is not any of the individual elements…But what is important is having all the elements together as a system. It must be practiced every day in a very consistent manner, not in spurts.

The slower but consistent tortoise causes less waste and is more desirable than the speedy hare that races ahead and then stops occasionally to doze. The Toyota Production System can be realized only when all the workers become tortoises.

Something is wrong if workers do not look around each day, find things that are tedious or boring, and then rewrite the procedures. Even last month's manual should be out of date

Standards should not be forced down from above but rather set by the production workers themselves.

Data is of course important in manufacturing, but I place the greatest emphasis on facts.

If you are going to do TPS you must do it all the way. You also need to change the way you think. You need to change how you look at things.
