Appropriate for marketing and operations management courses. The director of CS at a customer-focused catalog electronics company has asked a Six Sigma Black Belt for assistance in evaluating several ideas to effectively obtain and analyze feedback from users of its CS department. A Design For Six Sigma project was run six years previously and discovering why the company used the Six Sigma project, as opposed to one of the many new customer-satisfaction-survey tools available from third-party vendors is a goal. Students are asked to discuss the Design For Six Sigma methodology as it applies to the project.

The U.S. Customs and Border Protection reports that counterfeit goods seizures were up 83% in 2006. While a plethora of anti-counterfeiting strategies target distribution channels, international organizations, pirates, and company-based initiatives, few reports debate the effectiveness of these distinct anti-counterfeiting tactics to curb the problem. For this study we conducted in-depth interviews with United States managers to gauge the efficacy of various anti-counterfeiting tactics to preserve intellectual property rights. The results indicate that corporate managers find the practice of encouraging distributors to notify the manufacturer about counterfeits, as well as educating both employees and channel members about the counterfeit problem, to be some of the most effective ways to fight pirates. However, the managers report many other tactics are futile, including providing financial incentives for distributors to reject counterfeits and stressing the harmful effects of fake goods in advertising. We recommend a specific program that firms can employ to deter counterfeiting, including managing the registration of all trademarks and patents in key markets, establishing a company-based enforcement team, monitoring the growth of fakes through a central information repository, developing a multi-pronged action plan, and preparing to fight pirates through investigative work in conjunction with local law enforcement.

In the nearly 30 years since it was introduced, Six Sigma has evolved to mean different things in different circumstances and in different organizations, so that now it is difficult to identify a single, universally accepted definition. The purpose of this note is to provide a basic overview of Six Sigma by explaining its underlying principles and most commonly utilized methods while providing a brief review of its history. Finally, this note provides a brief summary of a Six Sigma case study illustrating the practical application of Six Sigma.
