, What is Six Sigma? - answerIt is a process that allows companies to improve their
business activities by finding ways to minimize waste and resources while increasing
customer satisfaction."
In Six Sigma, the common measurement index is DPMO (Defects Per Million
Operations) and can include anything from a component, piece of material, or line of
code, to an administrative form, time frame or distance.
How is Six Sigma Measured? - answer.A sigma quality level offers an indicator of how
often defects are likely to occur, where a higher sigma quality level indicates a process
that is less likely to create defects. Consequently, as sigma level of quality increases,
product reliability improves, the need for testing and inspection diminishes, work in
progress declines, cycle time goes down, costs go down, and customer satisfaction
goes up.
6sigma = 3.4 DPMO
