Robust, Producible Design Process Evolution

Summary:  [This abstract is based on the authors' abstract.] As recently as a decade ago, design engineering and manufacturing at GE Aviation were separate organizations. Nonconformance control by a material review board was used by design engineering to monitor manufacturing quality. While this process produced excellent engines, it depended on quality inspection, multiple rework loops, and resulting high costs. An evolving process used to design engines that are producible and error proofed is discussed, including the organizational structure needed to support the culture change. Examples are included that demonstrate the significant improvements in quality and producibility achieved by the new process.
