is that it is a management philosophy. Six sigma is a customer based approach
realizing that defects are expensive. Fewer defects mean lower costs and improved customer
loyalty. The lowest cost, high value producer is the most competitive provider of goods
and services. Six sigma is a way to achieve strategic business results.
Another answer to what is six sigma is six sigma is a
statistic. Six sigma processes will produce less than 3.4 defects or mistakes per million
opportunities. Many successful six sigma projects do not achieve a 3.4 ppm or less defect
rate. That just indicates that there is still opportunity.
A third answer to what is six sigma is that six sigma is a
process. To implement the six sigma management philosophy and achieve the six sigma level
of 3.4 defects per million opportunities or less there is a process that is
used. The six sigma process is define, measure, analyze, improve and control DMAIC.
When answering the question what is six sigma understand
