What Is Lean Six Sigma Green Belt Training?
Lean Six Sigma Green Belt training teaches professionals how to improve a defined process using structured problem-solving, evidence and the DMAIC method. Lean helps remove delay and non-value-adding work; Six Sigma helps understand variation, defects and process performance.
A Green Belt can lead a scoped improvement project, work with process owners and specialists, interpret appropriate data and help a team convert analysis into a controlled operational improvement.
Why Choose EduDelphi for Green Belt Training?
Live practitioner teaching
Learn the judgement behind each tool, not only its definition or formula.
Complete project simulation
Work from problem definition and baseline evidence through improvement and control.
Serious exam practice
Use 3,000+ questions, multiple timed mocks and full simulator assessments.
Practical Minitab learning
Follow guided demonstrations and exercises for appropriate statistical analysis.
Direct faculty support
Ask technical questions, review errors and obtain guidance on weaker areas.
Flexible UK delivery
Study in London, live online, self-paced, one-to-one or through a private corporate cohort.
What You Will Be Able to Do
The course is designed around the decisions a Green Belt makes during a real improvement project.
- Write a measurable problem statement, goal and project charter.
- Translate customer needs into useful Critical-to-Quality measures.
- Map a process and plan proportionate data collection.
- Assess baseline performance and interpret process capability.
- Separate symptoms, assumptions and validated root causes.
- Select, prioritise and pilot practical improvements.
- Use FMEA, controls and response plans to sustain change.
- Communicate evidence and benefits to sponsors and stakeholders.
Decision-making from data
Green Belt work is not a checklist of charts. You need to recognise what the problem requires, select a proportionate method, interpret the evidence correctly and avoid making a conclusion the data does not support.
That practical judgement runs through the teaching, cases, question reviews and project simulation.
Who Should Take the Green Belt Course?
Green Belt is suitable for professionals who improve processes, manage operational performance or contribute to business transformation.
Quality and improvement
Quality, continuous-improvement, operational-excellence and process professionals.
Operations and engineering
Manufacturing, engineering, production, maintenance and service-operations professionals.
Supply chain
Planning, procurement, logistics, inventory, warehousing and fulfilment teams.
Services and technology
Banking, insurance, technology, shared-services and customer-operations teams.
Healthcare and public service
NHS, healthcare, life-sciences, public-sector and government-supplier professionals.
Projects and transformation
Project managers, change professionals, analysts, consultants and team leaders.
No formal Yellow Belt prerequisite is required for EduDelphi’s Green Belt course. The course establishes the necessary Lean Six Sigma foundations before moving into Green Belt application.

See How We Teach a Green Belt Decision
A service team has reduced average handling time, but customer rework has increased and total lead time has not improved. The sponsor proposes adding staff. What should the Green Belt do first?
What is being tested?
Diagnosis before solution selection and the difference between a local metric and end-to-end performance.
Why B is strongest
Rework may be offsetting the handling-time improvement. The Green Belt should validate the constraint and root cause first.
Why the others are weaker
A and C prescribe changes without evidence. D attempts to control a solution that has not been validated.
This is an original EduDelphi teaching scenario. It is not an official, live or recalled certification examination question.
Green Belt LMS, Practice Questions & Mock Exams
The learning system supports class preparation, structured practice, revision and examination readiness.
Recordings and LMS
Return to lessons, supporting notes, mind maps and revision assets.
3,000+ questions
Practise and revise by topic, tool and DMAIC stage.
Mocks and simulator
Use multiple timed tests and full exam-simulator mocks.
Faculty support
Review technical questions, mistakes and weaker areas with guidance.
Learners may use the available tests and faculty feedback to assess readiness without making a separate final assessment compulsory for every EduDelphi preparation route.

Lean Six Sigma Green Belt FAQs
What is a Lean Six Sigma Green Belt?
A Green Belt is a professional who can use the DMAIC method and appropriate Lean Six Sigma tools to lead a scoped process-improvement project or support a more complex programme.
Is Lean Six Sigma different from Six Sigma?
Lean focuses strongly on flow, customer value and removing non-value-adding work. Six Sigma focuses strongly on defects, variation and evidence from process data. Modern Green Belt courses commonly combine both.
How long is the EduDelphi Green Belt course?
The standard live course includes 40 guided hours. It can be delivered as a five-day intensive or through an equivalent flexible schedule, including evening and weekend options.
Do I need Yellow Belt before Green Belt?
No. EduDelphi’s course includes the necessary foundations before progressing into Green Belt-level DMAIC application.
Does the course include statistics?
Yes. The course covers proportionate statistical thinking and selected analytical tools used during Measure, Analyse and Control. The emphasis is on selecting and interpreting methods correctly.
Is Minitab required?
The course includes practical Minitab demonstrations and guided exercises. Ask the team about the exact learning setup for your selected delivery route.
Does the course include a project?
Yes. Every standard course includes a complete simulated DMAIC capstone. Additional coaching for your own workplace project is available as an optional premium route.
What does the PECB route include?
The separate PECB package includes the applicable official PECB training and examination components together with EduDelphi teaching and support. Your quotation will confirm the current inclusions.
Do I need three years of experience to take the PECB exam?
No. The experience requirement applies to the full PECB Certified Six Sigma Green Belt credential tier, not simply to attending training or sitting the exam. A Provisional Green Belt route is available under current PECB rules.
Can EduDelphi arrange a route other than PECB?
Yes. Other certification pathways can be arranged where required and available. Tell the adviser which framework, employer requirement or assessment route you need.
Is the course available in London?
Yes. London classroom delivery is available. Dates and arrangements are confirmed through the UK course team.
Can I study live online anywhere in the UK?
Yes. UK-friendly live-online options are available nationwide, with recordings and supporting LMS access.
Is a final EduDelphi assessment compulsory?
No. Readiness and final assessments are available as part of the learning and examination-preparation process, but a separate final assessment is not compulsory for every EduDelphi preparation route.
How much does the Green Belt course cost?
Fees are enquiry-led because the EduDelphi preparation route, the separate PECB package and optional workplace-project support contain different components. Request a written quotation for the route you need.
Can my employer pay by invoice or purchase order?
Yes. Employer invoicing, purchase-order support and private corporate arrangements are available.
