The ATU Sligo Lean Sigma Green Belt provides participants with enhanced problem-solving skills, using the DMAIC (Define, Measure, Analyse, Improve and Control) model. This course will show you how to reduce cost, increase quality, improve speed and make processes more effective and efficient in your organisation. This Green Belt course covers the use of statistical, analytical and operational improvement tools to improve processes using a structured problem-solving methodology.

Through practical examples and exercises, learners will become proficient in the use of the problem-solving techniques used to monitor and control processes. This ‘learning by doing’ approach also allows for better integration of the tools into the participant’s workplace.

2	Lean & Operational Excellence (OpEx) During this course, we will study the application of Lean and Operational Excellence (OpEx) principles, including the Shingo model for operational excellence. Lean is widely considered to originate from the world-class manufacturing techniques of the Japanese auto industry and in particular the Toyota Production System (TPS). Lean and OpEx been embraced by leading global companies in the manufacturing and service sectors and are now the foremost process improvement approach for organisations that wish to attain world-class performance in quality and customer satisfaction by eliminating 'waste' in their processes. In Lean terms 'waste' refers to anything that does not add value to the product or service in the eyes of the customer. The Lean tools are a key component and enabler of Operational Excellence where problem-solving, teamwork and leadership results in continuous improvement in the workplace. Although originating in manufacturing, the Lean tools and techniques are also being used in healthcare, banking and government sectors where benefits have been achieved in productivity, efficiency, and cost reduction. Learning Outcomes 1. Describe the key principles of Lean and Operational Excellence (OpEx) and how theycan be used to drive continuous improvement and competitive advantage in an organisation. e.g. Lean transformation, Strategy deployment. 2. Recognise the potential sources of waste in a process and identify the appropriate Lean tool(s) to measureand reduce/eliminate that waste. e.g. Leader Standard Work (LSW), Audits, Gemba waste elimination walks. 3. Demonstrate the application of typical Lean tools such as Value Stream Mapping,SMED, Error Proofing, 5S, Visual Management, TPM, Kaizen Events, in creating a continuous flow. 4. Identify and use the appropriate metrics and Key Performance Indicators (KPIs)to improve process performance in terms of quality, throughput, productivity and cost. e.g. Yield, Lead time, Cycle time, Downtime and Efficiency. 5. Demonstrate the use of problem-solving tools such as 5-Whys, Brainstorming, Cause & Effect (Fishbone)andA3sheets in Root Cause Analysis (RCA).	05	Elective
1	Six Sigma 1 – Introduction to Lean Sigma Quality Six Sigma 1 ‑ Introduction to Lean Sigma quality aims to provide learners with an understanding of the tools and techniques of quality that are used in the attainment of a six-sigma quality environment. The principal goal of Six Sigma is to reduce variation in the process and improve quality. Through practical examples and exercises, learners will become proficient in the use of the basic problem-solving techniques used to monitor and control processes. The topics include: the Six Sigma DMAIC problem-solving process, Lean principles, FMEA's and risk management, the seven traditional quality tools, surveys, descriptive statistics and an introduction to inferential statistics. The module now includes lectures on Minitab – the industry-leading Six Sigma statistical software. This module is also designed to meet the requirements of the Six Sigma Yellow belt award. This module aligns with the internationally recognised Six Sigma Green Belt body of knowledge from the American Society for Quality (ASQ) and also from Quality America. As this is an online course, the majority of students are working in industry. Learning Outcomes 1. Describe why organisations use Six Sigma andthe Design for Six Sigma (DFSS) and DMAIC improvement methodology. 2. Define and describe Lean concepts and tools 3. Define, select and use the seven quality tools for problems solving, prioritising problems and improving processes. eg. Cause & Effect, Scatter Plots and Pareto charts. 4. Define, select and use the seven (new) management and planning tools. eg. Affinity diagrams, matrix diagrams and tree diagrams 5. Generate FMEAs and understand how they are used in risk management. 6. Calculate process performance metrics such as DPU, FTY, DPMO and Cost of Poor Quality (COPQ). 7. Collect and summarise data using surveys, descriptive and inferential statistics and graphical methods.	05	Mandatory
Year	Project Six Sigma 3 The project aims to provide students with the opportunity to apply and integrate the skills and knowledge they have gained on the programme. For students in employment, the project should address a substantive issue in the workplace. The project will test the student’s ability to define a real-life problem of concern to the organisation, design a strategy for addressing the problem, gather data, formulate and evaluate options and make recommendations. The project must follow the DMAIC problem-solving methodology using Lean and/or Six Sigma tools. For students not in employment and unable to complete a work-based project, then a simulated Lean Six Sigma project option may be undertaken. This will consist of reviewing six sigma case studies, analysing the data and using the appropriate Six Sigma tools and Minitab statistical software to identify the solutions to the problem. A mentor will be assigned to each project, which may be individual or in some cases group projects. The mentor will act as a guide in agreeing the relevance, and scope of the project and monitor the progress on a regular basis. There will be regular contact between the student and their mentor as the project progresses throughout the semester. Updates will be sent to the mentor on an agreed basis. Learning Outcomes 1. Identify a problem which needs to be addressed of importance to the organisation. 2. Utilise an appropriate structured approach to manage the project with realistic, interim and overall project objectives. 3. Identify and use the appropriate Lean Six Sigma tools to address the problem and implement the required solution(s). 4. Present project results with Executive Summary, Conclusions and Recommendations and justify the approach that was taken and the results achieved.	05	Mandatory

There is no requirement to attend Sligo as all lectures are delivered live online each week
which you can log into from your home or workplace. Recordings are also available if you cannot log into
the live lecture. If completing the Six Sigma 2 module, there may be a requirement to attend a final exam
held in May each year in an exam centre in Sligo or Dublin.

What are the prerequisites for the Lean Six Sigma Green Belt course?

Applicants are expected to have passed Leaving Certificate or equivalent in math’s due to the
Statistics covered in the course syllabus. It is preferable that you would be in a position to complete a
Lean Six Sigma Green Belt project with an employer. If you are unable to complete a Lean Six Sigma
work-based project, a simulated Six Sigma project can be completed. More details on the project
requirements are listed below.

Do I need to complete the Yellow Belt before enrolling on the Green Belt course?

No – The Green Belt course covers all of the material on the Yellow Belt course. If you first
enrol onto the Lean & OpEx Yellow Belt and then wish to continue onto the Green Belt course, you will
be exempt from the Lean & Opex module. You will then need to complete the Six Sigma 1 module and a
project to obtain your Green Belt.

What are the lecture days and times?

There are approx. 1.5 – 2 hours of lectures delivered live online each week. Live lectures are
scheduled between 6 pm and 10 pm from Monday – Thursday each week. The actual day and time of
your online lecture will be provided to you before lectures commence. These lectures are also recorded so
you can watch them anytime if you cannot attend the live lecture.

How much study time is required per week?

Previous participants stated that they spent on average 3 – 5 hours per week studying the course
material and completing any quizzes or assignments that are due that week. If you are already familiar
with some of the topics from your prior work or educational experience, this may be less. For the Project,
this can be done as part of your work schedule and we estimate this should take 3 – 6 hours per week
during the second semester.

What type of exams are needed to pass this course?

The Six Sigma 1 and the Lean & OpEx modules are assessed through a combination of
continuous assessment and a final online exam. For the Six Sigma 3 module there is a project
presentation and report to be completed. These are all submitted online.
If completing the Six Sigma 2 module, there may be a requirement to attend a final written exam held in
May each year in an exam centre in Sligo or Dublin

Is there an induction programme for new students?

Yes – you will be notified of the details of the online the induction once you register on the course.

If I fail in any of the exams, what is the provision to repeat?

Repeat exams are held in August. There is a nominal repeat exam fee – approx. €75. You can
repeat the exams up to a maximum of three times.

What type of work-based project needs to be completed for a Six Sigma Green Belt?

The work-based project will test the student’s ability to define a real-life problem of concern to
the organisation, design a strategy for addressing the problem, gather data, formulate and evaluate options
and make recommendations. A financial saving must be identified for Green Belt projects. The
target savings should be approx. €1250 Euros per month or €15K per year. However, we recognise that
this is somewhat dependent on the size of the company you work in and your role in the organisation.
You will have an opportunity to discuss this in more detail with your lecturer and IT Sligo project
supervisor.
Examples of typical projects:
Any Lean or Six Sigma project that seeks to improve quality, reduce time and have a financial
saving.
Quality improvement/defect reduction
Reduce lab turnaround time
Reduce accounts payable invoice processing costs
Reduced machine setup time

How long does the course last?

The course duration is 2 semesters (28 weeks). The course will run from September – December
and from Jan – April each year. You may enrol in either September or January. Previous participants
have stated that this gives the optimum learning experience and allows you to use the Lean Six Sigma
tools in your workplace.

Do you provide an alternative project if I cannot complete a work-based project with
my employer?

Yes – if you are unable to complete a work-based project, a simulated Lean Six Sigma project
will be provided by your lecturer to allow you to use the Six Sigma tools and the Minitab statistical
analysis software.

What will be the QQI level of credits I will receive by completing this course?

You receive 15 credits at Level 7 if you successfully complete all three modules. You will
receive a Certificate in Lean Sigma Quality from Atlantic Technological University.

Do I have to take all three modules in one year?

We recommend that you try and complete the Green Belt from September – May each year. If
required, modules can be studied over a longer period of time – up to 2 years. For example, you can take
the Six Sigma 1 & 2 modules during the first year followed by the Six Sigma 3 project module the
following year. You will receive 5 credits for each module you successfully complete. Please check the
course schedule as modules are normally only offered in one semester.

What are the ATU course fees?

The course fees are listed on the ATU website. The costs shown include course fees, examinations fees, access to the online lectures, access to the learning management system Moodle where course notes and reading material are provided. Access to Minitab software is also included during Lean Sigma Green Belt the course. The only additional cost for the student is the course textbook which is estimated to be approx. €65 per student.

Are there any grants available for course fees?

The course has in the past been grant aided by the Irish government under the Springboard
initiative for those applicants not in employment and a 90% funding for those in employment. If
Springboard funding available for this year’s course, this will be listed on the Green Belt course page on
the ATU website www.atu.ie/springboard.
