Dr. Sheryl Sorby heads up the new MTU curriculum program designed forprivate sector industries, including training in Six Sigma methodologies.WSU Offers MS and PhD Degrees inQuality Management/EngineeringStudents interested in quality management and quality engineeringcareers can pursue master’s and doctoral degreespecializations through Wayne State University’s highlyrespected Department of Industrial and Manufacturing EngineeringDepartment. Learn Six Sigma principles and design,quality management systems, quality assurance and control,reliability estimation, robust design, advanced quality engineeringand value engineering from top experts in their areas.Six Sigma courses are taught by Professor Kai Yang, author ofSix Sigma textbooks and a world-reknown expert (see articlepage 23). Hands-on learning, industrial partnerships, facultyexperts: three good reasons why students at WSU’s College ofEngineering receive a world-class education in the real world.For more information, please contact: http://mie.eng.wayne.edu/ or Ratna Babu Chinnam r_chinnam@wayne.edu or KaiYang kyang1@wayne.edu.Wayne State University’s Manufacturing Engineering buildingMTU New Curriculum: Engineeringfor the Service IndustryEngineering students are generally taught how to design andbuild products—better machines, instruments and other devicesor manufacturing processes—rather than services. However, theservice sector accounts for nearly 80% of all economic activity inthe United States. An interdisciplinary team at Michigan Techhas developed a new undergraduate engineering curriculumespecially for industries within the service sector. “If engineeringknow-how can be used to reduce health care costs, imagine theresulting savings in the cost of producing manufactured goods,”notes Dr. Sheryl Sorby, Associate Dean of the College of Engineering.Sorby received a $500,000 NSF grant to develop theprogram, which will launch in fall 2007. Six Sigma concepts willbe included in the new curriculum. In addition, Michigan Techoffers a number of excellent courses on Quality Engineering andDesigned Experiments, including an online course, AdvancedQuality Engineering, through ME-EM Distance Learning.For more information, please contact: Dr. Sheryl Sorby,Michigan Technological University College of Engineering,906-487-2005, sheryl@mtu.edu or www.doe.mtu.edu.Kettering’s IME Program 1st in NationKettering University’s undergraduateIndustrial andManufacturing Engineering(IME) program has beenranked first in the nationseven years in a row by theU.S. News and World Report—America’s Best Colleges Edition.One of the concentrations inthe IME curriculum is QualityAssurance; it combinestheory, hands-on laboratoryexperience and integratedinter-disciplinary projects toenhance learning.

Six SigmaFig.in a NutshellFundamentalBeliefs1. Six Sigmaas a BusinessStrategyBY Kai YangOrganizationalInfrastructureProjectExecutionix Sigma is one of the most successful businessmanagement systems ever developed. MotorolaCorp. developed the first Six Sigma initiative inthe mid-1980s. In 1995, the Six Sigma systemgained publicity after Jack Welch, former CEO ofGeneral Electric (GE), made this system a centralfocus of his business strategy and used it to transformGE into one of America’s flagship companies.GE’s remarkable success was contagious, and over thelast ten years, thousands of companies all over the world haveimplemented their own Six Sigma programs. The Six Sigmamovement is credited with generating greatly improved operationalefficiencies and billions of dollars in savings.What is Six Sigma?The name ‘Six Sigma’ comes from statistical terminology: TheGreek symbol sigma (σ) represents standard deviation. For anormal statistical distribution, the probability of falling within± 6 sigma range of the statistical mean is 0.9999966, or almost100%. In production and manufacturing processes, the “SixSigma Standard” means that a process will produce defectiveproducts at the rate of 3.4 defects per million units. Therefore,Six Sigma quality is a valid indicator of an extremely lowdefective rate in a very high-quality process. Six Sigma is notjust statistical jargon; it is a proven, comprehensive businessstrategy with multiple aspects, or components (Fig. 1).Six Sigma Fundamental Beliefs1. Do the right things and do things right.“Doing the right thing” means that we have to designabsolutely the best product or service in terms of customervalues. ‘Doing things right’ means not only having a gooddesign, but also that we will make all our products, servicesor processesperform consistentlyso allcustomers will besatisfied at all times.2. Process is everything.TrainingMethods andToolsSix Sigma is a process-focused approach tobusiness improvement, with the key feature of improvingone process at a time. The process here could be a productionsystem, a business process or a product-usage process.Compared with other quality initiatives, the Six Sigmasystem applies not only to product quality, but also to allaspects of business operation by improving key processes.For example, Six Sigma may help create well-designed,highly reliable and consistent customer billing systems, costcontrol systems and project management systems.Organizational InfrastructureIn order to achieve perfect products and processes in abusiness enterprise, Six Sigma needs to build an organizationalinfrastructure to manage and execute Six Sigma improvementactivities (Fig. 2).Six Sigma Terminology• Champion: Champion is a person responsible for coordinatinga business roadmap to achieve Six Sigma qualitygoals. A champion selects Six Sigma projects, executescontrol and alleviates roadblocks for the Six Sigma projectsin a given area of responsibility.• Master Black Belt: Master Black Belt is a mentor, trainerand coach of Black Belts and others in the organization. AMaster Black Belt brings the broad organization up to therequired Six Sigma professional competency level.www.esd.org | The Engineering Society of Detroit | 23
