Lean Six Sigma Green Belt +

In-depth training that prepares participants to lead & contribute to Lean Six Sigma efforts & project teams.

This class includes 12 days of classroom training spread over four months, with individual coaching between classes. Participants complete a real-world, instructor-guided project as part of certification. Includes the introductory course to Lean Leadership, the Leading with Lean Short Course.

Course Description: 

Lean and Six Sigma are proven, complementary business mentalities for maximizing customer satisfaction and improving quality by reducing defects, process waste, and variation. When properly applied on carefully selected improvement projects, businesses can achieve significant productivity and financial gains. 

The Lean Six Sigma Green Belt program delivers in-depth training, preparing participants to successfully lead and contribute to process-level improvement projects. Attendees will gain practical insight into the five-step DMAIC model—Define, Measure, Analyze, Improve, Control—and how it is used to apply a variety of Lean and Six Sigma principles and tools to reduce defects and waste, and then, to verify the effectiveness of the solutions. This course is a blend of lecture and application, emphasizing individual and small group exercises and interactive simulations, in a stimulating and active training environment. 

Newly added is the integration of Leading with Lean, a leadership course providing both formal and informal leaders the basic awareness of how the Lean mentality can be incorporated into the daily interaction with employees, customers, and the processes within the larger value stream to which they all contribute. The managers, supervisors, project sponsors and Champions working directly with the LSS Green Belt candidate will be invited to attend and participate in this session. 

Attendees do not need to have any previous process improvement experience prior to training. The workshop is concluded with a coached project, wherein each participant will apply the concepts learned to a real-world project assigned to them by their management sponsor. Each Green Belt candidate must demonstrate the ability to implement process improvement using Lean Six Sigma methodologies. Green Belt certification requires attending training, a comprehensive project report, and the completion and review of a Lean Six Sigma Green Belt project.

Lean Six Sigma Green Belt Objectives 

After certification, Lean Six Sigma Green Belts usually function as members of process improvement action teams within their functional area. Green Belts typically work under the supervision and mentorship of a Black Belt and may be associated team leaders in a closely scoped project or sub-project. These projects may be completed within the scope of their normal daily roles. In less complex situations, Green Belts may also lead process improvement efforts that do not require the statistical rigor of a Black Belt.  

Upon completion, participants will be able to: 

  • Apply the basic Six Sigma tools and methodologies 
  • Think critically and use data-driven approaches to solving problems following the DMAIC model 
  • Define, scope and create project charters 
  • Develop process and value-stream maps 
  • Develop cause and effect diagrams 
  • Demonstrate basic statistical analyses 
  • Understand and apply the following elements of Six Sigma techniques: 
    • Effective data collection techniques 
    • Process capability 
    • Process and control FMEA 
    • THypothesis tests 
    • Mistake-proofing (Poka Yoke) 
    • SPC charts 
    • Control plans 
  • Apply Lean/Six Sigma tools to track day-to-day process/project improvements 
  • Report results in a structured format  

Credit for this course is CEU based on the Clock Hour system. Participants will receive 9.6 CEUs.

General LSS Green Belt certification requires: 

  • Successful completion of coursework 
  • Participating in discussions and project review meetings 
  • Successful completion and review of your Lean Six Sigma Green Belt project 
  • Comprehensive project presentation live via Zoom supported by a written report

Projects are considered completed when there has been evidence of improvement on project goals through a pilot or full organization implementation.
