Supply chain management - everyone is talking about it, but few companies are truly conquering the concept. Successful supply chain management requires communication and cooperation throughout the extended enterprise. The Automotive Industry Action Group (AIAG) - a not-for-profit trade association of 1,300 member companies - is working to improve supply chain communications in the automotive industry. AIAG volunteers have identified more than $2 billion in potential savings to the North American automotive industry just by improving communication. These cost saving initiatives include streamlining electronic communication and business processes as they relate to electronic commerce and CAD/CAM data exchange. AIAG is also working to improve the efficiency and effectiveness of electronic communication throughout the supply chain by creating a dedicated "business" internet for the automotive industry called the Automotive Network eXchange (ANX).
