The principles of lean are used to optimize processes and performance with the focus on speed, efficiency and the removal of waste. The Lean Green Belt certification has been developed in partnership with the Lean Six Sigma Academy (LSSA) and is based on the ‘Continuous Improvement Maturity Model’ (CIMM), a framework that guides an evolutionary staged approach for process improvement from an early stage.
The purpose of the Green Belt qualification is to confirm that a candidate has sufficient knowledge, understanding and application of the Lean process improvement methodology, practice and analytical tools to be able to work effectively as the team leader of Lean process improvement projects or as a member of a Black Belt process improvement project, within an environment supporting Lean.
Candidates can gain certification against either or both the Theory and Practical levels. The Theory level involves undertaking a multiple-choice format exam and is a pre-requisite for the Practical level. The Practical level involves submitting one practical Lean project for assessment.
Find out more at the ISSA website.
The examination is supported by either of the following books:
- Climbing the Mountain - Mindset, skill set and toolset for Lean Six Sigma Green Belts – (first 6 chapters only)
- Training is supported by the Lean Six Sigma Green & Black Belt Exercises book:
Candidates can study for the Lean Green Belt exam using either the 2021 editions of these books, or earlier versions.
The Lean Green Belt theory exam is available in English and Dutch.
Lean Green Belt Practical Assessments can be submitted in either English or Dutch – the templates are available to download in both languages.
The main publication Climbing the Mountain - Mindset, skill set and toolset for Lean Six Sigma Green is available in English only.
For individuals self-studying it is almost impossible to say. As all candidates have different experience and amount of time available for study, it varies from person to person. We suggest you buy the manual and have a look through for yourself before deciding how long you need to spend learning.
For those studying with an accredited training organization, Lean Green Belt courses are generally delivered over 5 days. It is well worth investigating with individual providers, as some will offer tailored, online or blended learning solutions.
Please see below for the structure of the Lean Green Belt certification:
Theory exam:
- 40 multiple choice questions.
- 25 marks (63%) or more required to pass.
- 120 minutes duration.
- Open-book (a maximum of any two books is permitted during the exam + statistical tables booklet (14 page PDF). Exercise books are NOT permitted during the exam.).
- Calculators and minitab are permitted.
Practical assessment:
- One successful project at CIMM level-III (or higher) must be submitted.
- The project has a financial impact of at least € 20,000 on an annual basis or another CTQ (like Lead Time) has been substantially improved.
- The project must follow the PDCA, DMAIC or DMADV roadmap.
- Projects should be signed off by the Champion. They hereby declare that the project has been carried out professionally and that objectives have been achieved and are sustainable.
- The language of the submitted project must be in English or Dutch.
- Practical assessments must be submitted no later than three years after passing the Lean Green Belt theoretical examination.
The project will be assessed by Master Black Belts assigned by the LSSA.
The result of the practical assessment will be either Pass or Fail. No score will be given.
In the event of a ‘Fail’ result, brief guidance will be given on those criteria that are deemed ‘Missing’ or ‘Incorrect’. Subsequently, a single retake resubmission is permitted.
Candidates are permitted a maximum of 2 books in the exam. Candidates are also permitted to use calculators. No other materials can be taken into the exam.
The Lean Green Belt theory exam does not expire. However, candidates must submit a practical assessment within 3 years of passing the theory exam so that they can be awarded the ‘full’ Lean Green Belt certificate.
The pass mark for the Lean Green Belt theory exam is 25 out of 40 (63%).
To upgrade from Lean Green Belt to Lean Six Sigma Green Belt, candidates will need to attend a Lean Six Sigma 5-day training course and then sit the Lean Six Sigma Green Belt Theory exam.
