Development of a new product requires the product development team to address many complex customer requirements during the commercialization process. Consider a situation in which a new product being developed must meet specified upper and lower specification limits based on Voice of the Customer interviews. The design team must model and understand the sources of potential variation in the new product that need to be monitored and controlled if the product is to meet the identified customer needs. The process of analyzing component variation and designing a final product that meets customer tolerance requirements is known as statistical tolerancing.
In this Short Cut, various Design for Six Sigma techniques for determining the impact of multiple sources of variation on a final product are examined in detail. A procedure is described for using representative models for individual product components to estimate the expected overall level of variation in the performance of a final product.
Three methods of tolerance analysis are presented and the merits of each are discussed: Worst Case Analysis, Root Sum of Squares Analysis, and Six Sigma Tolerance Analysis. A detailed case study example, involving multiple sources of variation, is employed to illustrate the application of these methods. Minitab® is used to identify the best-fitting distributions from data sets for individual components. Monte Carlo Simulation with Crystal Ball® is then employed to determine the most important individual sources of variation and the overall variation of the final product. Finally, Crystal Ball's OptQuest® optimization feature is utilized to determine the required design value for each key parameter to meet final customer requirements.

About the Authors
Successful development and commercialization of new products are critical to the long term viability of any business. The primary goal of product development is to enable a company to meet its goals for profitability and growth by introducing new, improved and innovative products to the market. The failure of a company to commercialize valuable new product ideas results in the commoditization of that company's product portfolio and potential failure of the business itself.
In this short cut we examine the business reasons that lead a company to adopt and implement the Design for Six Sigma methodology. During our discussion we examine the product life cycle that all products undergo, beginning with product development and ending with product decline. The impact of new, disruptive technologies on current products is also examined and illustrated with a case study example involving the replacement of vacuum tube technology by the transistor.
In addition, an examination of the economics of new product introduction is presented, describing the impact of low priced substitute and "surpriser and delighter" products on existing markets. Using traditional supply/demand economic analysis in combination with the Kano model, the authors explain the dynamic forces which move existing products from premium pricing to a state of commoditization. Finally, the authors take a detailed look at the financial metrics used to measure success in a DFSS project. During this portion of the chapter the authors discuss financial metrics such as Net Present Value; key reasons for failed commercialization programs; and the use of financial sensitivity analysis, including Monte Carlo simulation techniques.
This short cut describes in detail how DFSS brings value to companies. Using the language of business, the authors outline how Design for Six Sigma helps companies identify the needs of customers and emerging product trends through the use of a well defined, structured process. The authors also provides the reader with an understanding of how DFSS can be used to counter the forces of product commoditization and the entry of potentially disruptive technologies in the markets served by the business today.

To remain competitive, companies must become more effective at identifying, developing, and commercializing new products and services. Design for Six Sigma (DFSS) is the most powerful approach available for achieving these goals reliably and efficiently. Now, for the first time, there's a comprehensive, hands-on guide to utilizing DFSS in real-world product development.
Using a start-to-finish case study, a practical roadmap, and easy-to-use templates, Commercializing Great Products with Design for Six Sigma shows how to optimize every stage of product commercialization. Drawing on a combined sixty-five years of product experience, the authors show how to make better product and portfolio decisions; develop better business cases and benefits assessments; create better concepts and designs; scale up manufacturing more effectively; and execute better launches.
