Six Sigma is a comprehensive and flexible system for achieving, sustaining and maximizing business success by minimizing defects and variability in process. It relies on TQM.TQM: A philosophy that stress on three principles for high performance and quality of process. Customer satisfaction Employee involvementContinues improvement in performance.Six Sigma having less than 3.4 defects per million opportunities or a success rate of 99.9997% where sigma is a term used to represent the variation about the process average .Why is it called as six sigma? It is called six sigma because of the basic idea that if we have standard deviations between the process mean and specific limit then every item will meet the standard of that product.Steps in Six SigmaUnderstanding the customers needs

Disciplined use of facts, data and statistical analysis

Diligent attention to managing, improving and reinventing business process.

Reduce speedCenter processProcess on target with low variabilitySix sigma approach focuses on reducing speed and centering the process.7Importance of Six SigmaFocuses on reducing variation in processCentering the process on their target measures of performanceFlaw-too much variation or an off-target process, degrades the performance of the process.

Example of six sigma is mortgage department of a bank.

A five steps procedure that leads to improvements in process performance.

The model can be applied to

Projects involving incremental improvements to processesProjects requiring major changes

redesign of an existing processdevelopment of a new processSix Sigma Improvement model


1 Define:Determine the characteristics of the processs output that are critical to customer satisfactionIdentify the gaps between the characteristics and the process capabilitiesGet a picture of the current process by documenting it using flowcharts and process charts.

2 Measure:Quantify the work process does that affects the gap.Select what to measure, identify data sources and prepare a data collection plan.

3 Analyze:Use the data on measures to perform process analysisApply tools such scatter diagrams, cause-and-effect diagrams and the statistical control toolsDetermine where improvements are necessary.Establish procedures to make the desired outcome routine.

4 Improve:Modify or redesign the existing modes to meet the new performance objectivesImplement the changes.5 Control:Monitor the process to make sure that high performance levels are maintained.Once again use data analysis tools to control the process.BeltsSuccessful firms using six sigma develop a cadre of internal teachers who than are responsible for teaching and assisting teams involved in a process improvement project, these teachers are called BELTS.Types Of Belts:Green BeltsBlack BeltsMaster Black BeltsTypes Of Belts:1 Green Belts: Are the employees who achieved the first level of training in a six sigma program, spend a part of his/her time teaching and helping teams with their projects and rest of the time they do their assigned duties.Types Of Belts:2 Black Belts: Are the employees who have reached the highest level of training in six sigma program and spend all of their time teaching and leading teams involved in six sigma program.3 Master Black Belts: Are full time teachers who review and mentors black belts.
