  5. 5. Lean Design Lean Design is applying lean principles to Product Development Lean Design is achieved through a organized effort by a interdisciplinary team to develop, or improve a product that accomplishes the necessary functions that make it work and sell at the lowest possible lifecycle cost within the constraints of safety to the user and the environment. Lean Design focuses on "balanced excellence" in product design by focusing on the elimination of non-value-added waste in both the process of development and in the design of the products themselves. (Technology Perspectives, http://www.design-for-lean.com/lean%20design.html) Lean Design can be viewed as Value Engineering repackaged with improvements to the implementation phase using lean principles, DFM/A, and 3P. Lean Design requires the application of the VE methodology to be effectively applied. 5/21/2009 Wixson Value Associates Inc. 3
  6. 6. Waste in Product Development Reinvention Lean Design teams appreciate the value of knowledge, and ensure that knowledge is easy to capture, reuse and always used to make decisions, thus avoiding reinvention of key products or features Excess Requirements Lean Design teams recognize that every extra feature or performance enhancement must be designed, produced, maintained and supported – and customers pay the price in greater complexity and greater risk of failure (Design to Cost is important). Overloaded Resources Lean Design teams know that overloading resources makes them slower and less flexible, and that task-switching costs engineers valuable time. Unintegrated Design Lean Design teams strive to understand and then manage their designs in an integrated system, so that they can focus innovation on areas that improve the market performance of their entire portfolio of products. 5/21/2009 Wixson Value Associates Inc. 4

  10. 10. What is Value Engineering? VE is an intensive, interdisciplinary problem solving activity. VE is uses an organized approach toward problem solving. VE focuses on the functions performed by products, products, or services and what is required to perform these functions safely and at the lowest possible cost consistent with customer requirements. 5/21/2009 Wixson Value Associates Inc. 8
  11. 11. What is Value Engineering? Value Engineering is a proven methodology that has saved private industry and governmental agencies $Billions since its inception in 1947. Value Engineering can be used to generate significant cost savings and cost avoidance by identifying potential problems and ways to avoid these problems before they occur. The VE approach promotes the philosophy of “Do It Right the First Time.” 5/21/2009 Wixson Value Associates Inc. 9
  12. 12. Value Study Methodology The value team study process matches the “quick-hit”, “small team” process that Tom Peters and Nancy Austin describe in, A Passion for Excellence, as a powerful alternative to the “throw resources at it” approach to problem solving (Peters and Austin, 1985). The strength of the value team process we use is in the pre- study phase, especially when the Executive Review Board (ERB) members include the Customer (Air Force, Army, Navy, airlines, FAA, etc), and suppliers. (ERB is described in the attached pre-event paper.) 5/21/2009 Wixson Value Associates Inc. 10
  13. 13. VM, Six Sigma and Lean? Doing Things Right is the main focus of Lean and Six Sigma (Process Improvement) (Customer Satisfaction) Doing The Right Thing is the main focus of Value Methodology (Function/Cost balance) (Customer Perceived Value) Both Are Required for economic profit 5/21/2009 Wixson Value Associates Inc. 11
  14. 14. Lean Design - Goals Resource Efficient – LEAN Capable of very high yields regardless of volume Not affected by process variation: Robust Lead to a “flawless launch” Meets Performance Targets (Quality) Meets Delivery Targets (On Time) Meets Financial Targets (Target Cost) 5/21/2009 Wixson Value Associates Inc. 12

  16. 16. PPAP Production Part Approval Process: The Production Part Approval Process (PPAP) outlines the methods used for approval of production and service commodities, including bulk materials, up to and including part submission warrant in the Advanced Quality Planning process. The purpose of the PPAP process is to ensure that suppliers of components comply with the design specification and can run consistently without affecting the customer line and improving the quality systems. PPAP ensures that you will achieve the first time quality and will lower down the cost of quality. 5/21/2009 Wixson Value Associates Inc. 14

  26. 26. Creating a Culture for Innovation Innovation is not a solo sport despite all the mythology. It requires a team using a well structured work session. “Innovation comes far more often from a diverse team, freely exchanging ideas, than it does from a solitary genius or an insulated team with the occasional “aha” moment along the way.” Jim McNerney 5/21/2009 Wixson Value Associates Inc. 24

  29. 29. Definitions Value Study - The overarching objective of a value study is to improve the value of the project. Job Plan – Provides the structure for the Value Study which is part of a three-stage process which includes: 1. Pre-Workshop preparation 2. Value Workshop which applies the Six Phase Job Plan 3. Post-Workshop documentation and implementation Value Methodology – Provides the process and structure that is used to apply the Value Job Plan used in the Workshop. Value Standard – Establishes the specific six-phase sequential Job Plan process and outlines the objectives of each of those phases. It does not standardize the specific activities that are used to accomplish each phase. Value Engineering Study: A study used in the design phases of product development to establish the functions, target costs, and preferred alternative(s) for a new, or revised product. Value Analysis Study: A study on an existing product used to improve product performance, lower cost or improve reliability and maintainability. Note: Value Engineering and Value Analysis are often used synonymously and are encompassed by the term “Value Methodology.” LDB/P: Lean Design Build Process – An VM study supported by DFMA and 3P.

  50. 50. Benefits of Functional Thinking The function analysis system technique process (FAST) helps task teams plan projects, develop technical and business processes and procedures, and modify organizations for leaner, more effective performance. FAST displays functionally what has to be done and identifies dependent functions (how) and the reason for selecting those functions (why). Thinking functionally shifts paradigms and helps task teams innovate by changing the way they normally think about solving problems and capturing opportunities. Two basic questions are at the heart of FAST Why? and How? If ask strategically they will open the door to a wealth of information hidden under levels of assumptions and misinformation Once learned, thinking and speaking functionally allows team members to communicate with anyone, regardless of their technical or professional background. 5/21/2009 Wixson Value Associates Inc. 48
