Introduction

Expand/Collapse Expand/Collapse

Lean Six Sigma combines two of the most powerful business improvement methodologies: Lean, which reduces waste and improves process speed and Six Sigma, which minimises defects and enhances capability. Together, they enable impactful improvements across industries. 

Our Yellow Belt Programme offers a practical and supported introduction to these principles. Delivered using a team-based approach, learners apply the DMAIC methodology to solve real-world process challenges, guided by expert Tutors. This QQI Level 6 accredited programme is designed to develop practical skills that make a real difference. 

It is the perfect starting point for individuals who want to begin using Lean Six Sigma to drive improvement in their workplace. At the same time, it offers organisations an excellent way to start building a culture of continuous improvement. Team members apply the tools and techniques to a small project within their own work area, gaining valuable experience and creating a solid foundation for further progress. 

What's covered?

Expand/Collapse Expand/Collapse

The 3-day practical Yellow Belt Programme (delivered over 6 weeks) is designed for team-based, project-focused learning. Learners work in small groups, applying DMAIC to real improvement opportunities identified in their organisations. Tutor mentoring and feedback are provided throughout, ensuring learners develop practical competencies.

Structure:

  • Day 1: Focuses on the Define and Measure phases. Following Day 1, teams will have an action plan to characterise and investigate the process opportunity.
  • Day 2: Focuses on the Analyse, Improve and Control phases. Each team will provide a detailed update on their project, receive Tutor feedback and begin developing and implementing appropriate solutions to verify their impact.
  • Day 3: Each team will meet individually with the Tutor to review project objectives, deliverables and documented improvements. The Tutor will mentor and advise the teams before each presents their project for evaluation.

We can customise the programme to the specific needs of an organisation or industry, aligning examples, case studies and tool selection to an organisations processes. This will ensure the learning is immediately relevant and practical.
