You have to manage a system. The system doesn't manage itself.
Divide responsibility and nobody is responsible.
Quality is everyone's responsibility.
Hard work and best efforts will not by themselves dig us out of the pit.
It is important that an aim never be defined in terms of a specific activity or method. It must always relate to a better life for everyone.
Anybody can achieve gains in quality by slowing down production. That is not what we are talking about.
