Certified Lean Six Sigma Green Belt (CLSSGB)

Master Process Improvement, Operational Excellence, and Data-Driven Decision Making

The Certified Lean Six Sigma Green Belt (CLSSGB) programme is a comprehensive, professionally structured certification designed to equip learners with the practical knowledge, analytical capability, and leadership competence required to drive measurable process improvements across organisations. Built around internationally recognised Lean and Six Sigma methodologies, this course empowers professionals to reduce waste, minimise defects, optimise workflows, and deliver sustainable operational excellence.

In an increasingly competitive and data-driven business environment, organisations demand professionals who can translate analysis into action. The CLSSGB certification responds directly to this need by providing end-to-end mastery of the DMAIC framework, supported by Lean tools, statistical analysis techniques, and real-world problem-solving approaches applicable across manufacturing, services, healthcare, finance, logistics, education, and public sector environments.

Why Choose the CLSSGB Certification?

The CLSSGB programme is not a theoretical overview. It is a practical, job-ready qualification designed to develop professionals who can confidently participate in, lead, and support Lean Six Sigma projects.

This course is ideal for:

Quality professionals and process improvement specialists
Operations, supply chain, and project managers
Engineers, analysts, and business consultants
Team leaders seeking structured problem-solving capability
Professionals aiming to progress towards Black Belt certification

With 35+ detailed modules, the programme offers a structured learning journey that integrates Lean thinking, Six Sigma analytics, and leadership practice, ensuring learners are equipped to deliver tangible business outcomes.

Comprehensive Coverage of Lean Six Sigma Fundamentals

The programme begins with a strong conceptual foundation, introducing learners to the principles, history, and evolution of Lean Six Sigma. This ensures a clear understanding of why Lean Six Sigma works, how it has evolved across industries, and how it supports strategic business objectives such as cost reduction, customer satisfaction, quality improvement, and continuous improvement cultures.

Learners gain clarity on:

The relationship between Lean and Six Sigma
Business benefits of Lean Six Sigma adoption
Roles and responsibilities within Lean Six Sigma projects
The Green Belt’s position within organisational improvement structures

This foundation prepares learners to confidently apply the methodology in real organisational contexts.

Deep Dive into the DMAIC Methodology

At the core of the CLSSGB programme is a structured, in-depth exploration of the DMAIC framework—the globally recognised approach for systematic process improvement.

Define Phase

Learners develop the ability to:

Clearly define business problems and improvement opportunities
Establish project scope, objectives, and success criteria
Identify Critical-to-Quality (CTQ) requirements
Develop professional project charters aligned with business priorities

This phase ensures improvement initiatives are well-scoped, stakeholder-aligned, and strategically relevant.

Measure Phase

The programme builds strong measurement capability, enabling learners to:

Map end-to-end processes using structured process mapping techniques
Design effective data collection plans
Understand measurement systems and data reliability
Establish baseline performance metrics

These skills form the backbone of evidence-based decision-making and prevent subjective or assumption-driven improvement efforts.

Analyse Phase

Learners are trained to move beyond symptoms and identify true root causes of process inefficiencies and defects. This phase includes:

Root cause analysis tools and techniques
Understanding and analysing process variation
Hypothesis testing for root cause validation
Failure Modes and Effects Analysis (FMEA)

By mastering analytical rigour, learners gain the confidence to justify improvement decisions using data rather than intuition.

Improve Phase

This phase focuses on solution design and implementation, enabling learners to:

Generate and prioritise improvement ideas
Apply Lean tools to eliminate waste
Design and implement process improvements
Pilot solutions and validate improvements before full deployment

The emphasis is on practical, implementable improvements that deliver measurable results.

Control Phase

Sustaining improvement is critical. Learners develop the ability to:

Apply Statistical Process Control (SPC) techniques
Develop documentation and Standard Operating Procedures (SOPs)
Monitor performance and prevent regression
Close projects effectively and capture lessons learned

This ensures improvements are embedded into organisational systems and behaviours.

Mastery of Lean Six Sigma Tools and Data Analysis

Beyond DMAIC, the CLSSGB programme provides focused training on core Lean Six Sigma tools, including:

Value Stream Mapping
5S workplace organisation
Kanban systems for flow control
Total Productive Maintenance (TPM)

Learners also gain practical exposure to data analysis techniques, including descriptive and inferential statistics, process capability analysis, and control chart interpretation. Guidance is provided on using commonly applied statistical tools such as Excel and Minitab, ensuring learners can apply their knowledge using accessible, industry-standard software.

Leadership and Project Management Skills

Unlike many technical certifications, the CLSSGB programme recognises that successful improvement requires people skills as much as analytical ability. Dedicated modules focus on:

Leadership skills for Lean Six Sigma practitioners
Team building and cross-functional collaboration
Stakeholder management and communication
Managing resistance to change

These skills prepare learners to lead improvement initiatives with confidence, credibility, and influence.

Assessment, Certification, and Professional Recognition

Upon completion of the course content, learners undertake a 25-question multiple-choice final assessment, designed to test applied understanding of Lean Six Sigma concepts and tools. A 70% pass mark is required to successfully achieve certification.

Successful candidates are awarded the Certified Lean Six Sigma Green Belt (CLSSGB) certificate and may use the professional designation with their name, demonstrating verified competence in Lean Six Sigma methodologies and process improvement practice.

Career Impact and Organisational Value

Professionals holding the CLSSGB certification are highly valued across industries due to their ability to:

Improve efficiency and productivity
Reduce operational costs and waste
Enhance quality and customer satisfaction
Support continuous improvement initiatives
Contribute to data-driven decision-making

For organisations, CLSSGB-certified professionals represent capability builders who can translate strategy into operational excellence.
