Lean Produces Significant Resource Productivity Improvements with Important Environmental Improvement and Sustainability Implications. Through the adoption of a combination of Lean strategies (identifying and retooling the value chain, adopting product-aligned, cross-functional manufacturing, designing for manufacturability, and taking a “whole system view”), Boeing has substantially reduced the amount of energy, raw materials, and non-product output associated with its manufacturing processes. Overall, Boeing has realized resource productivity improvements ranging from 30 to 70 percent when Lean initiatives are implemented, and continues to improve on its overall efficiency and pollution output per unit of production. Results such as these have led many, including.
