Six Sigma Definition

Six Sigma provides the techniques and tools to improve the capability and reduce the defects in any business process.

Six Sigma is a methodology used to improve any existing business process by constantly reviewing and re-tuning the process. To achieve this, Six Sigma uses a methodology known as DMAIC (Define opportunities, Measure performance, Analyze opportunity, Improve performance, Control performance).

Six Sigma methodology can also be used to create a brand new business process using DFSS (Design For Six Sigma) principles.

Six Sigma Strives for perfection. It allows for only 3.4 defects per million opportunities for each product or service transaction.

Six Sigma relies heavily on statistical techniques to reduce defects and measure quality.

Six Sigma experts evaluate a business process and determine ways to improve upon the existing process.

Six Sigma experts can also design a brand new business process using DFSS (Design For Six Sigma) principles. Typically its easier to define a new process with DFSS principles than refining an existing process to reduce the defects. Six Sigma incorporates the basic principles and techniques used in Business, Statistics, and Engineering.

Six Sigma improves the process performance, decreases variation and maintains consistent quality of the process output. This leads to defect reduction and improvement in profits, product quality and customer satisfaction.
