The Lean Six Sigma Yellow Belt exam validates your understanding of Lean Six Sigma fundamentals and your readiness to support process-improvement projects. The exam focuses on the DMAIC framework at an introductory level, the seven wastes, basic process mapping, data collection, and the Yellow Belt's role within Lean Six Sigma project teams. Through a combination of multiple-choice questions, candidates are tested on their ability to apply Lean Six Sigma principles in real-world process-improvement environments.
A Yellow Belt is a recognised entry point into Ireland's thriving process improvement job market. With nine of the world's top 10 pharmaceutical companies and most leading medtech multinationals operating here, employers actively seek people who understand Lean and DMAIC. Foundational certification helps you step into quality analyst, continuous improvement and process support roles, then progress towards senior, better-paid positions as you add Green and Black Belt skills.

This Yellow Belt training gives you practical, job-ready capability across the full DMAIC cycle and core Lean tools. By the end, you can support process improvement projects, read basic quality data, and help teams reduce waste and variation.
In Yellow Belt training you learn to scope improvement problems using the Voice of the Customer, critical to quality characteristics, project charters and SIPOC, so you can frame a process issue clearly within the Define phase.
Build the skills to map processes and capture data using process mapping, basic statistics and quality metrics such as DPU, DPMO and first time yield, the core of the Measure phase.
Learn to investigate variation and find root causes with fishbone diagrams, Pareto analysis and an introduction to hypothesis testing, so you can support sound, data-driven conclusions in the Analyse phase.
Understand how improvement ideas are tested and selected, with an introduction to correlation, regression and designed experiments at an awareness level, supporting the Improve phase.
Apply control tools that hold improvements in place, including 5S, Kanban, Poka-Yoke, statistical process control and simple control plans, central to the Control phase.
Recognise the seven wastes and use Lean concepts such as 5S and value stream thinking to spot inefficiency and contribute to a leaner, more reliable operation.
