All About the Six Sigma Process
Six Sigma is a measurement of quality that strives for near perfection. It is a disciplined, data-driven approach and methodology for eliminating defects in any process. The statistical representation of Six Sigma describes how a process performs. To achieve Six Sigma, a process must not produce more than 3.4 defects per million opportunities. A Six Sigma opportunity is the total quantity of chances for a defect. Process sigma can easily be calculated using a Six Sigma Calculator.
The fundamental objective of the Six Sigma methodology is the implementation of a measurement-based strategy that focuses on process improvement and variation reduction through the application of Six Sigma improvement projects. There are two Six Sigma methodologies: DMAIC and DMADV. The Six Sigma DMAIC process is an improvement system for existing processes falling below specifications. The Six Sigma DMADV process is an improvement system used to develop new processes or products at Six Sigma quality levels. Both Six Sigma processes are executed by Six Sigma Green Belts and Six Sigma Black Belts.
