Breyfogle, Implementing Six Sigma, 2003 DFLSS Tools: Life Cycle Planning The probability of a new product or service failure is highest in the early stages due to design or production flaws, and decreases and then levels out with usage e.g., initial problems with new cars or homes However, at some point, the probability of failure increases as parts wear out Some systems are repairable or replaceable, while others are not DFLSS planning must consider these factors DFLSS Tools: Life Cycle Planning Bathtub Curve Don’t Waste Money on Extended Warranties! Many stores recommend the purchase of extended warranties to go with consumer electronics. They are available for automobiles as well, but they are rarely if ever cost effective. The bathtub curve (a model for failure or hazard rates in reliability engineering,) explains why. How does this curve suggest the best way to prioritize defect reduction? DFLSS Tools: Simulation A method for replicating real world relationships with the aid of a computer Utilizes historical data and other knowledge Allows for the study of variation in processes Enables analysis without disrupting the real system Not an optimization technique - decision variables are inputs to a simulation DFLSS Tools: Design of Experiments DOE is a statistical procedure for conducting a controlled experiment, where the impact of high versus low settings of X’s are determined, including possible interactions Examples: Vary the time and temperature and amount of butter used to bake a batch of cookies. Vary elements of a website to measure the impact on customer click-through or purchase rates DFLSS Tools: Theory of Inventive Problem Solving (TRIZ) A combination of methods, tools, and a way of thinking developed in the Soviet Union in the 1940s Used for concept generation and problem-solving Assumes that all inventions contain at least one contradiction e.g., faster auto acceleration reduces fuel efficiency, productivity vs. accuracy, etc. Success depends on resolution of contradiction Involves trade-off between contradictory factors, or overcoming the contradiction Despite the immensity of problems, only 1250 typical system contradictions in 39 design parameters have been found to date Many Triz tools have been developed to deal with these contradictions Source: Design for Six Sigma, Yang and El-Haik, 2003 Lean and Single Supplier Strategy Advantages Reduction in variability Time saved dealing with many suppliers Volume discount from single supplier Minimized identification issues when field failures Priority access to supplier’s R&D breakthroughs Disadvantages Fewer brainstorming and competitive benchmarking opportunities Dependence on one supplier to get it right Potential loss of diversity of suppliers Other Lean Considerations Many organizational decisions negatively impact continuous flow Lean continuous flow is not always appropriate Multiple supplier relationships cannot support Lean Innovative products Need responsiveness and flexibility Single supplier strategy is needed, even for critical resources Need to partner with a supplier to achieve your Lean goals!
