An introduction to Six Sigma with a design example

An introductory tutorial on the concepts, principles, and application of Six Sigma in the design of electronic circuits is presented. First, Six Sigma is introduced, starting with a review of the underlying statistics. The statistics are combined with the description of quality goals in units of defects per million opportunities, and the origin of the term Six Sigma becomes obvious. The six steps to Six Sigma are presented and discussed. This methodology is applied to the design of a simple electronic circuit. Statistical simulations are used to predict defect density. Iteration of design revision and simulation are performed until the design is predicted to meet the desired quality goals
