Lean Six Sigma Green Belt



This one-week course is designed to help professionals gain a solid understanding of Lean Six Sigma techniques. Following the course they will be able to apply these skills to their own business problems utilising the DMAIC (Define-Measure-Analyse-Improve-Control) methodology. It is designed to explore these concepts through an interactive case study project where participants take an active role in significantly improving a business process.

The course will increase participants’ knowledge of the Lean Six Sigma mindset, focusing on the problem-solving tools within the methodology. This will increase their effectiveness in delivering both quality improvement and cycle-time reduction. Participants will gain an understanding of why gathering appropriate data is the key to determining root-causes, and how to deliver a sustained and quantifiable business improvement.

Training objectives

This programme will help participants:
  • Understand the main Lean Six Sigma concepts
  • See the impact of variation within their organisation
  • Understand the importance of flow and the impact of waste in business processes
  • Be able to effectively lead a Lean Six Sigma project using the DMAIC methodology
  • Apply the specific techniques within the DMAIC methodology to:
    – Understand customer requirements
    – Diagnose process performance
    – Establish a capability baseline
    – Identify improvement opportunities
    – Quantify and sustain process improvement 
  • Know where to apply Lean Six Sigma for maximum benefit
  • Understand some of the critical success factors in applying Lean Six Sigma


  • Professionals at all levels with an appetite for leading and delivering business improvement
  • Managers wishing to improve their business problem-solving skills


Six Sigma and Lean concepts are not new, but have been gaining increased prominence as a combined methodology over the past decade triggered by the increased availability of data and the constant need for businesses to improve. This course provides a solid grounding in the Lean and Six Sigma methodology through application in an interactive case study of a business improvement project. Participants progress through the case study moving from problem definition, measurement of performance, analysis to identify the root-causes of the problem, implementation of improvements, and control of the improved process. Having given participants a better appreciation of the components within Lean Six Sigma, the course concludes by exploring the challenges and opportunities in deploying Lean Six Sigma within an organisation.

We recommend that the group be limited to 12 participants if maximum benefit is to be had from the session.
