How is six sigma different from other approaches?

Six Sigma differs from traditional performance improvement programs in its focus on input variables and on the process. While traditional methods depend on measuring outputs and establishing control plans to shield customers from organizational defects, Six Sigma program demands that problems be addressed at the root level, eliminating the need for unnecessary inspection and rework processes. Also, while other programs mention philosophies, ideas, and requirements (e.g. ISO 9001 specifies requirements), Six Sigma provides a data driven structured road-map on how to bring improvement and change that leads to business benefits. Six Sigma as a strategic tool is customer focused and is ultimately designed to increase profits through enhanced customer satisfaction.

Just wanted to add a point results and the approach of Six sigma focuses on statistical significance.

VK _ Hope you agree.

Hi Tharun,

Yes Tharun, good points there.

• Six Sigma is a business result focused approach.
  
• Improvements made with a Six Sigma project need to be validated statistically as well as practically.
