All manufacturing industries are moving to a global production base through a combination of contract and internal manufacturing. Supply chain optimization for distributed manufacturing requires a combination of single-piece-flow Lean manufacturing with manufacturing operations management (MOM) systems to enable the distributed pull supply chains. Contrary to how Lean was applied to 20th Century Make-to-Stock supply chains, 21st century "pull" distributed supply chains are for global make-to-order (MTO) markets. Global MTO markets require real-time visibility of all forms of production capabilities and state of their resources to determine the most cost effective method for near 100% on-time-delivery. The resulting Supply chain management systems must be based on manufacturing integration standards to establish the foundation for "standard work" methods to enable a successful transformation to Lean manufacturing. This is an overview of the concept of Lean Production Management that explains this relationship between IT systems and Lean management methods.
