Continual improvement is an unending journey.
If there is no worker involvement, there is no quality system.
The only lifelong, reliable motivations are those that come from within, and one of the strongest of those is the joy and pride that grow fromknowing that you've just done something as well as you can do it.
It is not a question of how well each process works, the question is how well they all work together.
Nothing in life is static it either gets better, or it gets worse.
