2 The Six Sigma steps for many organizations are described as DMAIC Define: Select the appropriate response (the ‘Y’s, performance metrics) to be improved Measure: Data must be gathered to measure the response variable Analyze: Identify the root causes of defects, defectives or significant measurement deviations whether in or out of specifications. (The ‘X’s, independent variables) Improve: Reduce variability or eliminate the causes Control: With the desired improvement in place, monitor the process to sustain the improvement

3 ) X ,..., X , X , X ( f = Y k 3 2 1 Our Outputs (Y’s) are determined by our Inputs (X’s). If we know enough about our X’s we can accurately predict Y without having to measure it. Specifically, it is very important to find the following relationship, called transfer function: By knowing and controlling the X’s, we can set Y in right place, and reduce the variability in Y, which decrease the number of defects, cycle time, etc. We can also eliminate or reduce inspection, test, and rework. Specifically:
