The Lean Six-sigma concept is a set of tools and methodologies that rely on a collaborative team effort to improve performance by systematically removing waste; it combines the ideas of lean principles (or lean manufacturing, the lean enterprise) and the analytical tools of Six Sigma to eliminate variation and waste in business or manufacturing processes.

This Certificate in Lean Six Sigma Green Belt is suitable for employees who spend some of their time on process improvement teams or in analyzing and solving quality problems. Typical participants include managers, internal consultants, change agents, project managers and team leaders and should be working under the supervision of a Six Sigma Black Belt. The training provided on this programme provides participants with strong problem solving skills developed through the implementation of the DMAIC (Define, Measure, Analyse, Improve, Control) model. Learning to use many of the Six Sigma problem solving methodologies and statistical tools will equip participants with valuable skills to effect meaningful change in their organisations.

This programme is accredited at Level 7 on the National Framework of Qualifications for 15 credits.

The programme is made up of three modules, modelled on the DMAIC (Define, Measure, Analyse, Improve and Control) paradigm underlying Six-sigma itself.  Two of the modules deliver the essential course content of the programme, the Lean Principles, the Six-sigma paradigm including the DMAIC structure, and then the statistical tools underlying these ideas, In the third module the learner implements this knowledge in an improvement project.

Minimum Entry Requirements

This programme is typically aimed at applicants who have at least 2 years’ experience in an industrial, business or other organisational environment within which Lean Six Sigma can be applied. They must have a Leaving Certificate qualification, or equivalent.

Entry to the programme will be contingent on a suitable project being available for candidates to complete. The project undertaken during the six-sigma programme should be based in a relevant industrial or business context, and applicants will be expected to have identified a prospective project as part of their application, and be in a position to apply this in an appropriate industrial or business setting.

Course Aim

On completion of this course, participants will be able to:

  • Understand the concept of Six Sigma and the DMAIC approach to process improvement.
  • Understand the tools involved in the Define, Measure, Analyse, Improve and Control phases.
  • Understand the use of the tools in characterising processes, analysing process data, solving problems and controlling processes.
  • Use the key tools to solve practical business problems.

Lead small Six Sigma project teams or assist Black Belts to deliver tangible business results on larger projects


The programme is delivered over the two semesters of an academic year.

Semester 1 typically runs from mid-September until mid-December and semester 2 runs from late January (after the January exam session) to early May. Each semester lasts 12 - 13 weeks.

Course Content

Semester 1

Lean Principles and DMAIC – Define and Measure

This module covers the fundamental principles of Lean thinking as applied in an industrial and organisational context. The learner will study how to identify process and cultural elements required for any business improvement activities, including modes of group dynamics within teams and leadership skills. More broadly, these are the business and organisational factors that are crucial to the potential success of an improvement project. The learner then covers the DMAIC structure that underlies Six-Sigma and proceeds on to the Define and Measure stages of that process, including the project charter, the management and scope of the project and the descriptive statistics necessary for this topic, that is, the concepts behind the fundamental population parameters and the conventions needed to summarize and present large sets of data.

DMAIC – Analyse, Improve and Control

In this module the learners move on to the remaining elements of the Six-Sigma concept, the Analyse, Improve and Control methodology, tools and techniques. Further statistical tools are introduced to the learner and deployed to analyse and improve the source of waste in a process under investigation. The topic of statistical testing is covered here to allow the learner to rigorously test the improvements they have made to the process, and to show that the improvements they have made can be sustained.

Semester 2

Lean Six-Sigma Improvement Project

This project module is designed to provide students with an opportunity to undertake a substantial, individual Six-Sigma process improvement project, thus enabling the learner to consolidate, integrate and implement the knowledge and skills they have acquired in the other modules of this programme. Aside from enabling the learners’ intellectual development, this module has the additional personal development aim of developing the learners’ independence and confidence with the Lean and Six-Sigma techniques and methodologies.



A detailed timetable for the delivery of the programme will be published closer to the start of classes. Broadly speaking the statistics content will be delivered in a series of lectures online (typically eight three-hour lectures) and the Lean Principles and Six-Sigma content will be delivered on campus in two three-day intensive sessions. There will be one or two exceptions to this so please take care to note which are which when the timetable is released.

Please also take note that the exams take place during normal Institute exam times in mid-January. Exact dates will be confirmed in mid-semester.
