Six Sigma:

Six Sigma is a rigorous and a systematic methodology that utilizes information (management by facts) and statistical analysis to measure and improve a company's operational performance, practices and systems by identifying and preventing 'defects' in manufacturing and service-related processes in order to anticipate and exceed expectations of all stakeholders to accomplish effectiveness. The goal of Six Sigma is to increase profits by eliminating variability, defects and waste that undermine customer loyalty.

For an organization that operates in an extremely competitive industry where competition is fierce between arch rivals and companies try to outshine each other primarily on the basis of improved customer service and customer satisfaction, better quality and improved operational efficiency, quality tools like Six Sigma has become a necessity to sustain the competitive threats and to maintain the growth and profitability.

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. This is accomplished through the use of two Six Sigma sub-methodologies: DMAIC and DMADV. The Six Sigma DMAIC process (define, measure, analyze, improve, control) is an improvement system for existing processes falling below specification and looking for incremental improvement. The Six Sigma DMADV process (define, measure, analyze, design, verify) is an improvement system used to develop new processes or products at Six Sigma quality levels. It can also be employed if a current process requires more than just incremental improvement.
