For Whom

Those who have responsibility for quality or continuous improvement within their organisation including managers, engineers, supervisors and technicians. The programme is suited to a variety of industry sectors both in manufacturing and services, including the public sector.


Students are required to take three taught modules over two semesters. In addition to the taught modules, an in-company project will ensure a strong focus on the integration of the concepts tools and techniques in the participant’s organisation during the course of the programme. This course is delivered online but students may be invited on campus for an orientation day (on a Saturday) during their first semester.

In Company Project

Completion of this programme requires a substantial industry-based project, to be reported in the form of a management report.  

Six Sigma projects require the application of the concepts covered throughout the programme and carry an expectation of helping participant organisations realise a major benefit. This benefit should be quantifiable in terms of reduction or saving in; defects, over-production, waiting, non-utilised talent, transportation, inventory, motion, and/or extra-processing. 

Black Belt

The University of Limerick and several leading Irish companies designed this course to meet the standards of a black belt. While there is no single authority that issues Black Belts in Lean or Six Sigma, the industry group and university carried out extensive research in designing this course to ensure that the course met the general standards that are expected of a Black Belt holder. 

Successful participants will receive a letter from the University of Limerick stating that their capability is at black belt level. 

Semester 1
