What is Six Sigma?

Six sigmaSix Sigma is a methodology developed to power outstanding business performance by improving processes in order to reduce defects. The term “six sigma” refers to a statistical standard of excellence for processes -- no more than 3.4 defects per million opportunities.  Most processes produce 6,000 or more. For businesses striving to excel in an increasingly competitive world, that’s simply not good enough. Six Sigma methodology offers a way to cut costs, maximise results and dramatically improve performance.

What’s involved?

To achieve Six Sigma performance, a business must employ a systematic process-based methodology and project framework.  The methodology operates within a defined organisational deployment structure in which personnel at various levels operate and lead the Six Sigma implementation programme.

A typical Six Sigma programme involves:

  • Development of a strategic context, rationale and drivers
  • Executive development
  • Project champion development
  • Training of specialist Six Sigma practitioners (Black Belts and Master Black Belts) to lead Six Sigma projects
  • Training of local Six Sigma facilitators and operators (Green Belts and Yellow Belts)
  • Systematic project selection, management and review, usually focused on cost-measurable projects

What are the benefits?

  • Dramatically reduced defect rate, cycle time and cost
  • Reduced reliance on inspection for quality
  • Greatly improved customer satisfaction
  • Elimination of non value-adding work
