In a true zero-defects approach, there are no unimportant items.

Up until now, the aircraft carried no major defects.

And it has to do with having no inventory or stockpiles on the shelf, but items arrive as you need to build your product. What that means is that it's much more difficult to actually find stockpiles of already built weapons.

Quality has to be caused, not controlled.

Be willing to make decisions. That's the most important quality in a good leader. Don't fall victim to what I call the ready-aim-aim-aim-aim syndrome. You must be willing to fire.

A rule to live by: I won't use anything I can't explain in five minutes.
