1. Match the Six Sigma players to their corresponding roles (justify your choices): Roles and Responsibilities Six Sigma Players Works full-time on SS projects Black Belt Expert in statistics. Helps teams and resolves conflicts Master Black Belt Responsible for implementing solutions Process Owner Responsible for ensuring project completion and delivery of results Project Champion Works part-time on SS projects. Green Belt 2. (20 pts) Think about three specific examples of the seven wastes of Lean that could be addressed with a Six Sigma project. This could be at your workplace or a generic process you are familiar with. Then, try to operationalize the "what is wrong." Identify the process and where it occurs. What would be the primary metric associated with this project? Be concise. Use the table below as a reference. Waste Example Describe what is wrong Process Primary Metric Transportation Waste The train has inefficient headways and routing Increased power consumption, Bad review from customer, increased cost Evaluating transportation planning and route selection using historical data to optimize future routes Input Inventory Waste Often request 25% inventory based on conventional policy. For the new project it keeps the same %. Increased cost, can not update with new parts, unorganized stock room, Helps Create an inventory control process and configuration management process Output Motion Waste Maintenance team takes longer time to get the tools, spare parts, and information in their hand. Long time to troubleshot, compromised quality of repair, provide information on how process structure and work environment optimization might minimize motion waste. Input 3. (10 pts) What is a SIPOC diagram (map)? How is it used in the Define phase? SIPOC Diagram is a high-level process map and a tool that summarizes the Input and output of one or more processes in table or diagram form commonly used in the defined phase of the six sigma DMAIC.

It’s an acronym that stands for S= Supplier I= Input P=Process O=output C=Customer. The SIPOC diagram helps the company in determining how a process operates. It identifies the project's owner and server and makes an estimation of how well an input is utilized in the process. It also determines if the output is satisfactory and eliminate or create or change a process accordingly. This tool came out in 1980’s in use as part of the total quality movement. And today it is vastly used in six sigma, lean manufacturing, and BPM (Business Process Management) Using SIPOC in the Define step resembles the following: For example, In New York City Transit a systemwide cable replacement project is 2 years behind. We need to identify the process that we want to improve at the beginning of the project. Then identify the suppliers, Inputs outputs and the end users or the customers. In the very first steps we list down all the elements SIPOC diagram. For an Example: Supplier Input Process Output Customer 1. Cable company-EIS Wire and Cable 2.Tray Manufacturer- Selco 3. Installer and Contractor- Comstock 1. Scope of Work 2. Contractor Proposal 3. Proposed Schedule 4. Budget 5. Survey and Drawings 6. Cable Spec 7. Tray Spec 1. Review Contractor Proposal 2. Review Drawings 3. Inspect Cables and Trays 4. Inhouse Coordinator 5. Witness testing 6. Sign the deployment . 7. Accept Deliverables 1. Cables 2. Trays 3. Installation of New Cable 4. Installation of Cable Tray 1. New York City Transit 2. Department of Transportation
