Green Belt Lean Six Sigma DMAIC

Green Belt Lean Six sigma training Stanwick

What is lean?

Lean is a management philosophy and methodology that originated in the manufacturing sector, specifically at Toyota. The goal of Lean is to maximise customer value by eliminating waste and improving efficiency. It focuses on identifying and eliminating activities that do not add value to the product or service, such as waiting times, overproduction, unnecessary movements and defects.

What is six sigma?

Six Sigma originally originated at Motorola in the 1980s and has since spread as an effective approach to improving quality and reducing variation in processes. This systematic approach focuses on identifying and eliminating defects and aiming for only 3.4 defects per million opportunities. Through rigorous data analysis and statistical tools, Six Sigma helps organisations increase efficiency, reduce costs, systematically solve problems and improve customer satisfaction.

What is the Stanwick Lean Six Sigma Green Belt?

This "Process Improvement Methodologies” Lean Six Sigma Green Belt combines the rigorous, statistical approach of Six Sigma with the simplicity and speed of the Lean philosophy. This allows participants to achieve the challenging financial goals of their company faster and in a more efficient way. The continuous success of companies is more and more depending on the presence of specialised collaborators who can optimise processes in team as well as production, service and administrative processes.

Who is the Stanwick Lean Six Sigma Green Belt for?

The Stanwick Green Belt is the ideal entry level for team leaders active in process improvement. In our format, participants receive in-depth training in the essential components to lead and successfully complete a DMAIC project. They gain insight into the background and philosophy of process improvement techniques. They are trained in understanding and applying the various tools from both the LEAN and the SIX SIGMA toolbox. In addition, tools are also trained to smoothly guide the improvement initiative through the organisation.

What is the training program during the Stanwick Lean Six Sigma Green Belt?


  • Basic philosophy of Lean-Six Sigma DMAIC
  • Lean principles: value, value stream (mapping), create flow, establish pull, pursue perfection

  • Chronic vs. Acute variation: the Kepner-Tregoe approach to acute variation


  • Defining your process improvement project (business case, project charter, social contract, stakeholder analysis, communication plan)
  • Visualisation of the process (SIPOC, flow chart, value stream mapping, ...)
  • Voice-of-the-customer (KANO, CTQs, ...)
  • Building and managing your project team


  • Funnelling (priority matrix, FMEA)
  • Data collection plan (TAKT-time, lead time cycle time, operational definition, sampling,…)
  • Visualisation of data (histogram, Pareto chart, time plot, box-plot,…)


  • Root cause analysis (5 WHY’s, Ishikawa, 6 M’s)
  • Value added – Non value added analysis
  • Data-analysis (stratification, hypothesis-testing, regression)


  • Generate, evaluate and select the solutions (brainstorming, creativity, selection- and decision-making techniques)
  • Creating an efficient process: linking value added activities according to the pace and the demand of the customer
  • Lean Toolbox: 5S, line balancing, visual management, standard work, Kaizen, Poka Yoke,…

How does the Lean Six Sigma Green Belt Certification proceed?

Participants receive, after following the training and passing the exam, a Green Belt Training Certificate. If they want to receive a Green Belt Certificate, they need to successfully perform a process improvement project according to the DMAIC-roadmap. Stanwick can coach them during this project execution and after participating in the final presentation of the project hand them their Green Belt Certificate. Please do not hesitate to contact us if you want to receive more information on project certification.
