Lean Six Sigma Green Belt (LSSGB™)

Combine Lean Thinking with Six Sigma DMAIC to Reduce Waste, Analyze Variation, and Improve Process Performance

Ready to Improve Both Quality and Flow?

Process problems rarely come from one source alone.

A process can contain defects, excessive variation, unnecessary steps, delays, bottlenecks, handoffs, rework, and activities that do not create value.

Lean Six Sigma brings two complementary perspectives together: Six Sigma provides a structured, data-driven approach to reducing variation and defects, while Lean focuses on improving flow and reducing waste.

The Lean Six Sigma Green Belt (LSSGB™) certification develops structured knowledge of both approaches and how they can support process-improvement initiatives.

Reduce waste. Understand variation. Improve flow. Build better processes.

Course Description

The Lean Six Sigma Green Belt (LSSGB™) certification is issued by 6sigmastudy™ and focuses on understanding Six Sigma and Lean tools and techniques used to improve processes and minimise defects.

6sigmastudy™ places particular emphasis on understanding how these concepts can be applied within organisational improvement initiatives.

The curriculum combines areas such as:

• Six Sigma fundamentals
• The DMAIC methodology
• Process measurement and analysis
• Root-cause analysis
• Statistical process-improvement concepts
• Lean principles
• Waste reduction
• Process flow
• Value Stream Mapping
• 5S
• Kaizen
• Kanban
• Total Productive Maintenance concepts
• Continuous improvement

The objective is to help learners understand how Lean and Six Sigma can be combined within a structured process-improvement approach.

LSSGB™ develops improvement knowledge and analytical perspective. It does not replace practical workplace experience, technical expertise, or organisation-specific knowledge.

Prerequisite Education

There is no mandatory professional-experience prerequisite for LSSGB™.

6sigmastudy™ states that Six Sigma Yellow Belt (SSYB™) is preferable, but it is not mandatory.

Candidates can therefore begin Lean Six Sigma Green Belt without holding a previous Six Sigma certification.

Improve Quality Without Ignoring Waste.

Improving quality is important, but organisations also need efficient flow.

Common problems include:

• Recurring defects and rework
• Long process cycle times
• Unnecessary process steps
• Waiting and handoff delays
• Inconsistent process performance
• Decisions based on assumptions rather than data
• Bottlenecks that reduce throughput
• Improvements that are difficult to sustain

Lean Six Sigma provides tools for examining both process efficiency and process quality.

LSSGB™ introduces a structured method for identifying problems, measuring performance, analysing causes, improving processes, and sustaining improvements.

Who Should Join This Course?

6sigmastudy™ describes LSSGB™ as relevant to employees and organisations that need a standardised approach to problem solving and continuous improvement in Quality Management.

This can make the certification relevant to several professional profiles.

Quality & QA Professionals

Develop broader knowledge of process quality, variation, waste, measurement, improvement, and control.

Operations Professionals

Explore structured methods for improving process efficiency, flow, and operational performance.

Process Improvement Professionals

Combine DMAIC with Lean concepts such as waste reduction and Value Stream Mapping.

Continuous Improvement Professionals

Build a broader improvement toolkit combining Six Sigma analysis with Lean waste and flow concepts.

Manufacturing & Production Professionals

Develop additional understanding of process performance, defects, waste, flow, quality, and operational improvement.

Project Managers

Build complementary knowledge around project charters, stakeholders, metrics, analysis, and improvement planning.

Team Leaders & Supervisors

Develop structured problem-solving knowledge that can support operational teams and improvement initiatives.

Business & Data Analysts

Build additional understanding of process data, variation, root causes, performance metrics, and improvement opportunities.

LSSGB™ does not by itself qualify candidates for a specific job title or seniority level.

Barriers to Progress at This Stage

Defects Are Treated Without Improving Flow

A team may reduce one defect while leaving delays, unnecessary steps, and bottlenecks unchanged.

Waste Is Removed Without Understanding Variation

Efficiency initiatives can fail when underlying process instability is not measured or understood.

Root Causes Remain Hidden

Visible symptoms may be treated while the underlying process causes remain unchanged.

Improvement Projects Lack Structure

Teams may begin changing processes before defining objectives, measuring performance, or validating assumptions.

Improvements Are Not Sustained

Without control plans and monitoring, process performance can gradually return to previous levels.

LSSGB™ combines Lean and Six Sigma concepts to create a broader approach to structured process improvement.

The Solution: Combine DMAIC with Lean Thinking

Lean Six Sigma combines the structured Six Sigma DMAIC cycle with Lean concepts focused on waste, value, and process flow.

Define

Clarify the problem, stakeholders, objectives, requirements, metrics, and improvement-project scope.

Measure

Understand the current process, collect reliable data, validate measurements, and establish baseline performance.

Analyze

Identify root causes, variation, defects, bottlenecks, and non-value-added activities.

Improve

Evaluate potential solutions using Six Sigma analysis and Lean improvement approaches.

Control

Establish controls and monitoring intended to sustain the improved process.

Lean Perspective

Examine value, waste, process flow, Value Stream Mapping, workplace organisation, pull concepts, and continuous improvement alongside DMAIC.

The combined approach helps candidates understand both process variation and process efficiency.

What Makes LSSGB™ Different?

LSSGB™ combines Green Belt-level Six Sigma concepts with an explicit Lean component.

Key areas include:

• DMAIC methodology
• Project selection and planning
• Stakeholder requirements
• Measurement-system concepts
• Process capability
• Root-cause analysis
• Statistical analysis
• Statistical Process Control
• Lean principles
• Waste identification and reduction
• Value Stream Mapping
• Process-flow improvement
• 5S
• Kaizen
• Kanban
• Total Productive Maintenance concepts
• Continuous improvement

This makes LSSGB™ particularly relevant to learners who want to study both variation and defect reduction and Lean-focused waste and flow improvement within one certification pathway.

Your Transformation

Before LSSGB™	After LSSGB™
You may focus mainly on visible process problems.	You develop a structured perspective on defects, variation, waste, and flow.
Improvement decisions may rely heavily on intuition.	You gain greater awareness of data-driven DMAIC decision making.
Waste and defects may be analysed separately.	You understand how Lean and Six Sigma perspectives can complement each other.
Root causes may be difficult to distinguish from symptoms.	You gain exposure to structured analytical and root-cause techniques.
Improvements may not be maintained over time.	You develop greater awareness of process controls and sustaining improvements.

LSSGB™ provides structured knowledge and tools. It does not replace practical project leadership, advanced statistical expertise, or professional experience.
