The Six Sigma Green Belt is a certificate that professionals in Project Management prepare to implement the Lean Six Sigma methodology, with the purpose that companies optimize their processes: use of resources and reduce the variability of processes to eliminate waste.

This degree, awarded by the Lean Six Sigma Institute, is aimed at professionals already trained in the Lean Six Sigma methodology, who work on projects for continuous improvement. This is their main dedication, so it is convenient to acquire the most extensive knowledge of all aspects within the phases of DMAIC (Define, Measure, Analyze, Improve, and Control). Before preparing for the Six Sigma Green Belt, the professional already knows how to interpret and implement Six Sigma tools, as well as the principles of Lean Thinking and the Lean Six Sigma Body of Knowledge.

  • Green Belts typically work on projects within their own functional area.
  • Improve team facilitation skills by applying Lean thinking.
  • Development of project charter and SIPOC diagram (supplier, input, process, and output) for your project.

Despite this division, the experience of the professional who obtains a Six Sigma Green Belt is around 10 years, according to Payscale, which publishes that 27% of Green Belts have 1-4 years of work experience, 24% from 5 to 9 years of experience and the professionals who predominate to qualify for a Green Belt are between 10 and 19 years of experience in their sector.
