· Six Sigma is the process of producing high and improved quality output. This can be done in two phases – identification and elimination.
· The cause of defects is identified and appropriate elimination is done which reduces variation in whole processes.
· A six sigma method is one in which 99.99966% of all the products to be produced have the same features and are of free from defects.
Characteristics of Six Sigma
The Characteristics of Six Sigma are as follows:
Statistical Quality Control:
· Six Sigma is derived from the Greek Letter ? which denote Standard Deviation in statistics. Standard Deviation is used for measuring the quality of output.
Methodical Approach:
· Six Sigma is a systematic approach of application in DMAIC and DMADV which can be used to improve the quality of production. DMAIC means for Design-Measure- Analyze-Improve-Control. While DMADV stands for Design-Measure-Analyze-Design-Verify.
Fact and Data-Based Approach:
· The statistical and methodical method shows the scientific basis of the technique.
· Project and Objective-Based Focus:
· The Six Sigma process is implemented to focus on the requirements and conditions.
Customer Focus:
· The customer focus is fundamental to the Six Sigma approach. The quality improvement and control standards are based on specific customer requirements.
Teamwork Approach to Quality Management:
· The Six Sigma process requires organizations to get organized for improving quality.
