Six Sigma is a statistical approach to process improvement that aims to identify and remove defects. It was developed by Motorola in the 1970s to improve quality and reduce costs. Six Sigma seeks to reduce variation and errors in processes by using statistical methods and focuses on eliminating waste and increasing customer satisfaction. Major companies that have implemented Six Sigma include Motorola, GE, and Sony. The methodology aims for fast, measurable financial results within 4-8 months while ensuring the strategies become ingrained in the company culture over the long term. Some criticism argues it is merely an appraisal system and not a preventative approach, though proponents say appraisals are useful for tracking improvements. Success depends on proper use of tools and management support.

9. CRITISISM
There is nothing new. It only proves defects and defectives
counts offer tangible, measurable results.
It is corrective action system rather than taking a preventive
and proactive approach to problems.
It is merely about appraisal system and that appraisal programs
arent useful. In realty, appraisals are great tools for identifying
and tracking improvements, which is critical to any project.
Critics have suggested that Six Sigma did not bring quality
improvement in all the organizations where it was implemented.
It depends on the tools and authorizations.
