The aim of customer focus is on improving need/do interaction
Repetition of the same action constitute a process
Improve our business means improvement of our processes

As customer satisfaction improves, the likelihood of doing business increases
As business increases, we (as individual and society) grow and prosper
What is Six Sigma?
Sigma is a statistical unit of measure which reflects process capability. The sigma scale of measure is perfectly correlated to such characteristics as defects-per-unit, parts per million defective (PPM), and a probability of a failure/error.
The sigma value indicates how often defects are likely to occur. The higher the sigma value, the less likely a process will produce defects. As sigma increases, costs go down, cycle time goes down, and customer satisfaction goes up.
Six Sigma Is….
Six Sigma is disciplined methodology for continuous improvement for
Reducing process variability and keeping it reduced
achieve benefits from improvements in:
better product/process quality
reduce scarp and rework
reduce cycle time
better product/process design
reduce major expanses
A tool set to make that change practical
Empowered people have the control they need to improve the way they work
A common language for discussing, measuring and comparing process capabilities
A powerful competitive advantage……….
