One look at the kanban card in light of lean thinking helps those using it understand how and why it works, because they see it and understand it as a request, not a card.

You can read about the tools and techniques of lean in any book. You can delegate the application and implementation to just about anyone. But you cannot succeed without internalizing the principles of lean throughout all of management, and using that thinking to guide the implementation, daily decision making, problem solving, managing and coaching.
