Lean Six Sigma Green Belt training is an intermediate-to-advanced programme that develops practitioners capable of leading Lean improvement projects from problem identification through to sustained implementation. Green Belts can facilitate value stream mapping, run Kaizen events, analyse data, and drive measurable change within their organisation.
A Lean Six Sigma Green Belt course covers: Value Stream Mapping (VSM), process mapping, waste analysis, 5S/6S, standard work, root cause analysis (5 Whys, fishbone), PDCA, A3 problem solving, visual management, Kaizen facilitation, basic data analysis, and change management principles. Many programmes are project-based, requiring participants to complete a real improvement project for certification.
Lean Six Sigma Green Belt programmes typically run over 1–2 days of training, spread across several weeks to allow participants to apply learning between sessions. Project-based programmes may span 2–4 months in total, culminating in a project presentation or portfolio submission. This blended approach ensures skills are embedded and measurable results are delivered.
Yes. Lean Six Sigma Green Belt certification is widely recognised across construction, manufacturing, healthcare, and service industries. Accreditation from bodies such as the Chartered Quality Institute (CQI), IRCA, or the Lean Construction Institute adds further credibility. Employers value Green Belts as change agents who can deliver quantifiable ROI on improvement projects.
Organisations typically see a return of 3:1 to 10:1 on Green Belt training investment through project savings alone. Individual improvement projects often deliver somewhere savings of €20,000– €200,000 in waste reduction, rework elimination, and productivity gains. Beyond financial returns, Green Belts build internal capability that compounds over time as they develop future Yellow Belts.
