Session G3 - Integration of Theory of Constraints (TOC) with Lean Six Sigma, Enterprise-wide

This presentation shows how Theory of Constraints (TOC), Lean and Six Sigma are implemented in an integrated manner across an enterprise. For success, this “system of systems” approach requires large-scale integration across differing communities. The application is demand-focused logistics in a maintenance, repair and overhaul environment, from the point of consumption to the point of repair or overhaul, including suppliers.

This presentation will highlight the key steps of implementing TOC, Lean and Six Sigma in an integrated manner. It will start with an overview of how TOC, Lean and Six Sigma complement each other. Next, TOC principles will be outlined, such as Five Focusing Steps, the Drum-Buffer-Rope concept and Thinking Processes. Subsequently, details of the TOC-LSS integration effort will be presented starting with TOC Design Phase activities, followed by Activate, Improve and Sustainment phases. Success stories will be presented from the US Navy’s NAVAIR Enterprise AIRSpeed program, which encompasses Naval Aviation maintenance and supply. It will also highlight how some TOC tools, such as evaporating clouds and logical trees, can also be utilized for traditional Lean and Six Sigma applications.
