Six Sigma

The course on Six-Sigma will focus on detailed strategic and operational issues of process improvement and variation reduction. Six-sigma is a measure of quality that strives for near perfection. It is a disciplined, data-driven approach for eliminating defects (driving towards six standard deviations between the mean and the nearest specification limit) in any process-from manufacturing to transactional and from product to service.A Six-sigma defect is anything outside of customer specifications. To be tagged Six Sigma, a process must not produce more than 3.4 defects per million opportunities.Six-sigma employs a systematic approach of DMAIC (Define, Measure, Analyze, Improve and Control) for the process improvement. This course will provide a detailed understanding on various issues specific to each phase of DMAIC.The course is designed with a practical orientation and includes cases, industry examples and MINITAB software applications.The course is designed to satisfy the need of both industry professionals and University students.The content is beneficial to both manufacturing and service industry.INTENDED AUDIENCE : Mechanical Engineering, MBA, Industrial EngineeringPREREQUISITES : StatisticsINDUSTRY SUPPORT : Manufacturing and Service Industry
