Six Sigma Green Belt

August 4, 2011

I have been a great fan of six sigma methodology that I came across 3 years before in my last company. Now I got a chance to do a six sigma certification. Initially one has to do a green belt and then black belt. Yes, I got my green belt certification in Six Sigma methodology.

Basically Six Sigma is a quality improvement process suitable for any industry including manufacturing, retail, finance, IT etc. Higher the six sigma level, lesser the defects and greater will be the quality. Highest level that can be achieved is level 6 (and hence the name).. that is 3.4 defects per million opportunities (99.99966%). Six sigma is a comprehensive methodology referred as DMAIC principle.

The five phases of DMAIC are:

Define -> Measure -> Analyze -> Improve -> Control

Each phase is elaborate and need a detailed understanding of the project. If time permits, will write a collaborative posts on each phase.
