What is Six Sigma Green Belt?

Six Sigma Green Belt is the intermediate level of Lean Six Sigma certification. A Green Belt leads small-to-medium process improvement projects and supports Black Belts on larger initiatives, working part-time on improvement alongside their day job. Where a Yellow Belt contributes to projects, a Green Belt runs them end to end through the full DMAIC cycle — owning the data, scoping the problem and driving the solution to a measurable result.

Lean Six Sigma combines two proven disciplines into a single, data-driven approach for eliminating defects and waste in any business process. Lean removes non-value-adding steps; Six Sigma reduces variation. Together they help organisations reduce waste, minimise defects, improve efficiencies and lift bottom-line results. Importantly, when implemented correctly this is not an add-on to normal business activities. It becomes integral to how managers run operations and empowers employees to be more efficient in their own space, rather than being a tool for downsizing.

For South African employers the appeal is practical. A trained Green Belt can shorten a production cycle, reduce rework, cut customer complaints or free up working capital tied in slow processes — and can do so using data your business already generates. Because the method is sector-neutral, it applies as readily to a manufacturing line as to a claims department, a logistics operation, a finance back office or a public-sector service unit.

Lean Six Sigma Green Belt training: course overview

The Lean Six Sigma Green Belt (LSSGB) course gives delegates a working understanding of the Six Sigma and Lean tools and techniques used to improve the production process and minimise defects. Delegates learn to simplify complex business problems by analysing data for variation, then develop and implement practical solutions that hold over time.

The course teaches Basic Statistics (covered at Yellow and Green Belt) and introduces the analytical depth needed to move toward Advanced Statistics at Green and Black Belt level. Practice activities run during and between sessions so that learning is applied to real work, not just theory. By the end, delegates can charter a project, map a process, gather and interpret data, identify root causes, test improvements and put controls in place that keep the gains.

Who should attend

This course is built for the people your organisation relies on to make processes better:

• Operations, production and manufacturing managers
• Quality assurance and continuous improvement staff
• Team leaders and supervisors driving efficiency targets
• Project and process owners across services, finance and logistics
• HR and L&D buyers upskilling staff for a structured improvement programme

No prior Six Sigma qualification is required, though delegates who hold or understand Yellow Belt concepts move faster through the statistical content.

Lean Six Sigma Green Belt training: course outline

The programme runs across 10 structured modules, building from quality history through the full DMAIC cycle to a capstone case study.

1. History and Evolution of Quality — the contributions of Deming, Juran, JIT, Ishikawa and Taguchi, and the Six Sigma philosophy.
2. Overview of the Six Sigma DMAIC Process — the Define, Measure, Analyse, Improve, Control framework.
3. Stakeholders and Setting Up a Six Sigma Project — stakeholder identification, project selection criteria and team dynamics.
4. Six Sigma Methodology – Define Phase — project scope, objectives and core team identification.
5. Six Sigma Methodology – Measure Phase — data collection and current process performance analysis.
6. Six Sigma Methodology – Analyse Phase — root cause identification and analytical tools.
7. Six Sigma Methodology – Improve Phase — solution implementation and optimisation techniques.
8. Six Sigma Methodology – Control Phase — sustaining improvements and performance monitoring.
9. Lean Principles and Practices — waste elimination, Value Stream Mapping and supply chain optimisation.
10. Case Study — a comprehensive, real-life scenario that integrates every phase.

How delegates are certified

Successful completion requires passing all module exams provided by BOTI, plus the Case Study assessment. On completion delegates receive a Certificate of Attendance from BOTI and the 6sigmastudy Six Sigma Green Belt certification, recognised internationally. The exam day is built into the 8-day schedule, so delegates complete and certify within the same programme.

This is a practical, facilitator-led skills programme: the BOTI certificate is a certificate of completion and this is not an accredited (SETA/QCTO) qualification, while the Six Sigma Green Belt credential is awarded by 6sigmastudy, an independent international certification body. Need accredited training? Ask about BOTI’s QCTO/SETA-accredited programmes in related areas such as Generic Management and project management.

How the training is delivered

You choose the format that suits your team. In-house delivery brings the trainer to your premises, which keeps staff on site, reduces travel cost and lets the case study draw on your own processes. Off-site delivery at a venue suits smaller groups or teams that benefit from being away from daily interruptions. Remote delivery is available where teams are distributed across sites or cities. Whichever you choose, the course is instructor-led, practical and case-study based — rather than self-paced e-learning — so delegates get live coaching as they apply each tool.

Why choose BOTI for Lean Six Sigma Green Belt training

• Practical, not theoretical. Practice activities and a full case study mean delegates apply tools to your real processes during the course.
• Delivered where you are. In-house at your premises, off-site, or remote — across Johannesburg, Cape Town, Durban, Pretoria and other major centres.
• Globally recognised certification. 6sigmastudy is one of the largest Six Sigma accreditation bodies, with thousands of authorised training partners worldwide.
• Group pricing. Quote-based costing for 1, 3, 10 or more delegates, ideal for departmental or company-wide roll-outs.
• A clear belt pathway. Progress your people logically from Yellow Belt to Green Belt as their improvement responsibilities grow.

Funded and group training

If your organisation pays the Skills Development Levy (SDL, which is 1% of payroll), structured training such as Lean Six Sigma can form part of your annual Workplace Skills Plan and Annual Training Report, and may support your skills development scorecard. Under the B-BBEE codes the skills development target is measured at 6% of the leviable amount (not 6% of payroll), so it is worth planning a Green Belt roll-out alongside your other accredited and skills-programme spend to make the most of the points available. This is general guidance rather than financial or legal advice — speak to us about aligning a Green Belt roll-out with your skills strategy, and we’ll help you scope it.

Frequently asked questions

How long is the Lean Six Sigma Green Belt course?
It runs over 8 days: 7 days of instructor-led in-class training plus a dedicated exam day. It can be scheduled in-house or off-site to suit your team’s availability.

What certification do delegates receive?
On passing all module exams and the case study, delegates earn a Certificate of Attendance from BOTI and the 6sigmastudy Six Sigma Green Belt certification, which is recognised internationally.

Do delegates need a Yellow Belt first?
No. A Yellow Belt is not a prerequisite, but understanding Yellow Belt concepts helps delegates progress faster through the statistical content.

Where is the training delivered?
Off-site or in-house at your premises, in all major South African city centres including Johannesburg, Cape Town, Durban and Pretoria, with remote options available.
