What is Six Sigma?
The Six Sigma methodology, developed in 1986 by Motorola, is a company-wide technique
to achieve breakthroughs in productivity gains, PPM reduction, and in-cycle time
reduction. Motorola's creation of the original formula led them to unprecedented
growth, profitability, and recognition with the Malcolm Baldrige National Quality
Award in 1999.
Six Sigma provides businesses with the tools to improve the sigma capability of
their processes - leading to defect reduction and vast improvement in profits. Companies
with an effective infrastructure that remains consistent with the classic Six Sigma
system realize dramatic income improvements - often shortly after implementation.
Benefits of Six Sigma
By implementing Six Sigma wisely on carefully selected projects, companies will
- Improved customer satisfaction
- Reduced cycle times
- Increased productivity
- Improved process flow, capacity and output
- Reduction in total defects
- Increased product reliability
- Decreased work-in-process (WIP)
Six Sigma deployment is a company-wide strategy and technique to achieve breakthroughs
in productivity gains, PPM reduction, and in cycle time reduction. Though the training
is an important facet of the deployment strategy, Omnex believes the key to successful
implementation is the creation of a sustainable Six Sigma infrastructure.
Six Sigma is a statistical term that measures how much a process varies from perfection,
based on the number of defects per million units.
- One Sigma = 690,000 per million units
- Two Sigma = 308,000 per million units
- Three Sigma = 66,800 per million units
- Four Sigma = 6,210 per million units
- Five Sigma = 230 per million units
- Six Sigma = 3.4 per million units
Six Sigma, however, is in no way just statistical training. It's hands-on training
to complete a project that provides for savings greater than $125,000 for each project.
To graduate, Six Sigma Black Belt Trainees must effectively apply each of the techniques
taught -in the real world - in their own project.
Six Sigma Black Belts
There are three belts in Six Sigma, as follows:
Six Sigma Green Belt
An employee of an organization that will lead a process improvement or quality improvement
team. Green Belts are champions and supporters of Six Sigma.
Six Sigma Black Belt
A managerial level or technical specialist assigned full responsibility to implement
Six Sigma throughout the business unit.
- Develop, coach, and lead cross-functional process improvement teams.
- Mentor and advise management on prioritizing, planning and launching Six Sigma projects.
- Use, teach, and disseminate Six Sigma tools and methods to Green Belts and team
Black Belts have an in-depth understanding of Six Sigma philosophy, theory, strategy,
tactics, and quality management tools.
Six Sigma Master Black Belt
Master Black Belts are company-wide Six Sigma or quality experts. The Master Black
Belt is qualified to teach other Six Sigma facilitators the methodologies, tools,
and applications in all functions and levels of the company. In addition, the Master
Black Belt is able to provide leadership integrating the Six Sigma approach into
the business strategy of the company, and contributing to creating and carrying
out the organization's strategic business and operational plans. A Master Black
Belt has personally led several successful project teams.
Master Black Belts are qualified to teach the Green Belt and Black Belt curriculum.
