2. Topics> What is Lean? > What is Six Sigma? > Lean Six Sigma is > Key Roles & Responsibilities 2 3. Why Lean and Six Sigma > Six Sigma will eliminate defects but it will not address the question of how to optimize process flow > Lean principles exclude the advanced statistical tools often required to achieve the process capabilities needed to be truly 'lean > Each approach can result in dramatic improvement, while utilizing both methods simultaneously holds the promise of being able to address all types of process problems with the most appropriate toolkit. For example, inventory reduction not only requires reducing batch sizes and linking operations by using Lean, but also minimizing process variation by utilizing Six Sigma tools. 3 4. Lean is: A way to understand Value from the viewpoint of the customer and eliminate waste activities that dont add value A methodology to increase velocity and create a continuous flow of value-adding activities, pulled by the customer A set of tools to continuously improve this flowLEANRecommended reading: Lean Thinking, Womack and Jones (1996) 4Source: Rath & Strong 5.

Lean Six Sigma Requires Behavioral Change> Lean Six Sigma Challenges Us to: Think Differently Work Differently Ask Questions and Challenge the Status Quo Make Decisions With Facts and Data Use New Principles, Tools and MethodologiesEarly-on, when culture and change compete, culture wins.- Tom Quan, GlaxoSmithKline 13. Basic Questions > What are the customerneeds?> Do our products orservices answer the Voice of theCustomer at a price he is willing topay?> How do we know?13 14. Lean Six Sigma Principles Specify value in the eyes of the customer Identify the value stream and eliminate waste /variation Make value flow smoothly at the pull of thecustomer Involve, align and empower employees Continuously improve knowledge in pursuitof perfection 14 15. Definition of a Value Stream The VALUE STREAM is the entire set of processes or activities performed to transform the products and services into what is required by the customer.The VALUE STREAM Suppliers DesignProcure Make Sell CustomersA Primary Focus is TIME, Product and / or Service Flow Information Flow: Quickly In All Directions15 16. Understanding the Value StreamTheir SupplierOur SupplierOurHappy Piece Our Customer Customer Their Service> We are often part of a value creating stream> Ultimately, the intent of the stream is to answer theend-users needs> Knowing who our customers are is the first step inunderstanding the stream; our primary customer may not bethe end-user> Knowing how the stream and our piece works or doesntwork in meeting customer needs is what Lean Six Sigma isabout 16 17. Summarizing the Power of Lean Six Sigma Provides a world class business strategy Encourages a common vision and common languageshared by all Promotes teamwork and REWARDS success Combines aggressive goals with a method and a set oftools Requires the application of tools throughout entirelifecycle of a product or service Produces knowledge for improved cycle time, reduceddefects, and lower cost Better products and services delivered faster and at lower cost= Improved Customer Value17
