Aircraft Company X (AX) manufactures and assembles an immense variety of parts utilized as drive systems and rotor components across its multiple aircraft. The company's value proposition is maintaining the ability to build and service all legacy parts and as a result there is a great deal of variety found in its manufacturing processes. This variety stems from upgrades to manufacturing technology, improvements in material science, design variations, and individual part engineering modifications. In order to be responsive to fluctuating demand while minimizing costs, AX must broadly implement postponement into numerous applications as a way to extract the most value from its resources. This thesis uses multiple applications of postponement within AX to establish a methodology that can be used across various materials, both metallic and non-metallic. This methodology guided implementation of postponement through material physical form consolidation, material substitutions, and even provided insight into which manufacturing technique given a particular material form is optimal. The benefits are numerous to include a roughly 30% inventory reduction, improved buying power resulting in cost savings of over 10%, a reduction of material shortages by over 40%, and shorter lead times for finished goods. Extensions of these applications include aligning AX's supply chain with its suppliers utilizing identified tolerances and adding layers of postponement beyond raw material inputs.
