Despite publicized successes of Lean on the factory floor, manufacturers are still finding themselves adopting it slowly across the Enterprise, and beyond the shop floor. Reasons vary, from continued senior management commitment to the ability to quantify results beyond the plant floor. Although C-level executives are enthusiastic about the benefits that can be derived by "Leaning out" manufacturing operations from plant to plant, this study uncovered a large performance gap between those companies that are simply using Lean techniques on the shop floor versus those that have built a culture based on Lean thinking throughout the Enterprise and in particular, the supply chain. This study examines the degree and way that Lean has or will transcend manufacturing, and be adopted across the supply chain. It provides an understanding of the processes and measurements employed, current or planned benefits and the associated technology enabling solutions required to support Lean today and in the future.
