Many of the companies getting into the marketplace are talking about flow manufacturing. Flow manufacturing is whatever they want it to be or say it is. Demand Flow is based upon a set of principles, a set of mathematics, a set of tools. I'm probably the only person who has formalized the flow manufacturing industry by giving people specific tools, specific techniques. That's why I moved away from the philosophers.
Philosophers come and go.
Give me tools and techniques. The thing that I'd say John Costanza did is to give the industry tools. I believe if you give people good tools, they'll do great things. We've spoken about the theory of constraints vs. Demand Flow and how they can and can't work together. Give me your opinion of TOC vs. Demand Flow.
