Key Observations Information flow is bi-directional If our company doesn’t deliver value, someone else will (disintermediation) There’s only so much profit in a supply chain. Players in the chain collaberate by leveraging relationships, processes, and technology

Today’s environment Margins are down over the past years, end customer prices are down. Tighter delivery windows Offshore suppliers, lower cost, longer lead times Shorter product development cycles More service expectations Integration to drive down costs.
