Statistical Process Control for Six Sigma

Six Sigma is a quality-management methodology. It allows only 3.4 defects per million opportunities for a process, product or service transaction. In the Six Sigma context, a defect is considered anything that results in customer dissatisfaction.

Six Sigma relies heavily on statistical process control (SPC) methods to measure and reduce defects and increase quality. Specifically, control charts, run charts, histograms, Fishbone diagrams and Pareto charts are used in statistical process control software packages in order to measure and analyze the non-random variance in a process.
