A method for integrating Six Sigma into an inspection receiving process of outsourced products may include the following steps: defining specification limits for product acceptance criteria; identifying and reporting a substandard product to authorized personnel for disposition via a manufacturing execution system (MES) and supervisory control and data acquisition (SCADA); preparing a report containing historical data, identifying root cause and assigning a corrective action; segregating the substandard product, and documenting the substandard product in the MES; disposing the substandard product; documenting and recording the corrective action in the MES; and outlining a method of recovery and eliminating a non-conforming incoming product. The present method may provide a means for a closed loop corrective action (CLCA).
