Project Scope: Six Sigma
  • With the organizational pressure on managers to do Six Sigma, they often feel compelled to undertake improvement projects that do not have a high potential payoff just so they can say they are doing something. A lot of activity is often wasted on projects with low potential.

  • A tremendous upfront outlay of time and money is required. In a large organization, thousands of people are trained, tens of thousands of hours of organizational time and energy are absorbed, and millions of dollars of direct and indirect costs are incurred.

  • Six Sigma can easily digress into a bureaucratic exercise if the focus is on such things as the number of trained Black Belts and Green Belts, number of projects completed, etc. instead of bottom line savings.

  • The statistical definition of Six Sigma is 3.4 defects or failures per million opportunities. In service processes, a defect may be defined as anything which does not meet customer needs or expectations. It would be illogical to assume that all defects are equally bad when we calculate the Sigma Capability level of a process.

  • The tools used in Six Sigma are not powerful. A look at the American Society for Quality (ASQ) black belt curriculum reveals that the topics taught are simple statistical methods and statistical process-control techniques. In QualPro's experience, these methods yield about 10 percent of the total process improvement in a project, with MVT accounting for 90 percent.
