Speed of Implementation: Six Sigma

As outlined in Six Sigma Deployment, by Paul Keller, a Six Sigma deployment plan will follow this schedule:
  1. Management Commitment-Week Zero.
  2. Management Training-Week One
  3. Six Sigma Discovery-Weeks Two to Four.
  4. Champion Training, including Project Selection-Week Five.
  5. Black Belt Training-Weeks Six to Eighteen.
  6. Green Belt Training-Week Nineteen.
Keller adds that "realistically, you'll need some lag time between these activities to accommodate schedules, so that the five months indicated above becomes seven or eight in a fairly aggressive deployment."

Further, he states, "Six Sigma Discovery, is the most time-variant of the activities, ranging from several weeks to six months or more depending on the current practices of the organization and its size." (Emphasis added)

Six Sigma typically underestimates the amount of training required to become an effective Six Sigma black belt or process improvement expert. Internal training is often performed by black belts who themselves have only been exposed to four to five weeks of classroom training and a practice project. If any guidance is provided to newly trained persons attempting projects, it is provided by these process-improvement novices. The reality is that process improvement competence cannot be developed in only a few weeks or even a few months of Six Sigma training. Six Sigma black belt process improvement novices may get the low-hanging fruit (that is the obvious successes), but they will not be able to take the company to a whole new level of performance. Just as learning to use a hammer and saw does not make a master carpenter, learning to create flow charts and control charts or to perform t-tests and F-tests does not make a process improvement expert.

In contrast, an MVT® improvement project can be implemented in an organization with very little employee and management training, provided the organization has the assistance of a seasoned process improvement expert with advanced statistical training in multivariable testing. (See QualPro 12-Step MVT® Process) This competence can also be developed internally but the training process may take several years.

Since 1982, QualPro has used Multivariable Testing (MVT®) with 1000+ companies to test 100,000+ improvement ideas. MVT® tests between 20 and 40 ideas simultaneously, accurately predicting the bottom-line impact of potential process changes in as short as 12 weeks. Take existing process initiatives, like Six Sigma, to a whole new level. All process improvement tools and approaches (TQM, DOE, Six Sigma, Re-Engineering, SPC) can be enhanced through the use of Multivariable Testing® by QualPro.
