The Next Revolution in Supply Chain Management

I've been researching and writing about supply chain management for 20 years. I've seen a goodly number of "revolutions" in SCM. In the first revolution, the concept of supply chain, as opposed to logistics, was put forth. Constraint based optimization tools for the extended supply chain were developed to support the new philosophy. As this was going on, Lean and Six Sigma approaches to improving capabilities, not just at the factory level, but in other internal departments, as well as across the supplier and 3PL base, were gaining in strength.
