Efficiency is a by-product of removing waste. It isn't the goal. Who can argue against eliminating waste? =)

The next step is learning to see waste. And chasing radical ideas is not necessarily waste. Experimentation is not necessarily waste.

Toyota employs something called "set-based product development" where they develop multiple versions of a product at once. Talk about "wasteful experimentation."

Imagine developing three versions of a web site in Prototype, JQuery, and Flash -- all at the same time.
