A supply chain that expresses the Lean principles and therefore functions smoothly and as a whole rather than as a group of linked processes. 

The Lean fulfillment flow is constantly focused on reducing lead time by eliminating all non-value-added waste) activities at the suppliers and manufacturers who collectively create a product. This is accomplished through rigorous process discipline, inventory reduction and getting it right the first time. The Lean fulfillment flow follows customer demand; all activities within the supply chain are triggered by pull. The goal of the Lean fulfillment flow is to create the highest value for the customer at the lowest total cost to stakeholders (based on Martichenko and Von Grabe 2008).
