What Is a Lean Six Sigma Green Belt?
A Lean Six Sigma Green Belt is a practitioner who leads process-improvement initiatives within their business unit using the DMAIC framework (Define–Measure–Analyze–Improve–Control). Green Belts partner with Black Belts and project Champions to tackle process variation, reduce defects, and drive efficiency at the team level. Green Belts may also serve as a team member on more complex projects led by Black Belts, supporting collaborative process improvement efforts.
Key Responsibilities
- Project Leadership: Define scope, assemble cross-functional teams, and deliver measurable outcomes.
- Data Analysis: Apply statistical methods—control charts, hypothesis testing, capability studies—to validate improvements.
- Lean Tools Mastery: Use value-stream mapping, 5S, and Kaizen events to eliminate waste.
- Change Management: Engage stakeholders, document standard work, and sustain gains through control plans.
Belt-Level Comparison
| Belt Level | Focus | Training Hours | Project Scope |
|---|---|---|---|
| Yellow | Basic Lean Six Sigma awareness | 8–16 | Support team projects |
| Green | Lead DMAIC projects; advanced data analysis | 40–60 | Department-level improvements |
| Black | Enterprise-wide strategy; mentor Green Belts | 120+ | Strategic, cross-functional work |
The yellow belt is the foundational certification in the Lean Six Sigma hierarchy, providing an essential introduction before advancing to higher levels.
Accredited green belt certifications offer professionals industry-recognized credentials with flexible, self-paced learning options, making them valuable for those seeking credibility and customization across various industries.
Many professionals pursue a six sigma black belt after earning their Green Belt, as it is the next step for advanced training and project-based learning in their Lean Six Sigma journey.

Certification Bodies & Standards
There is no single global accreditor for Lean Six Sigma; instead, three major bodies administer Green Belt exams:
| Body | Exam Format | Duration | Cost (USD) | Recognition |
|---|---|---|---|---|
| ASQ | Closed-book, proctored exam (in-person or online) | 3 hours | 438 | Global, especially N. America |
| IASSC | Closed-book, proctored exam (in-person or online) | 3 hours | 295 | Global, especially Europe |
| CSSC | Open-book, proctored exam (in-person or online) | 2 hours | 250 | Global, growing in Asia |
- ASQ: Emphasizes both Lean and Six Sigma principles in a rigorous, closed-book, proctored exam format to ensure exam integrity.
