1. Introduction
Lean Six Sigma, also known as Define, Measure, Analyze, Improve, and Control (DMAIC) model, was originally
established by Motorola and is a continuous improvement method that is comprised of a process and a series
of tools which are implemented on a project basis in order to achieve a desired result, such as defect reduction,
process improvement or any other strategically aligned organizational objectives.
The Lean Six Sigma method
Lean Six Sigma is a method that relies on a collaborative team effort to improve performance by systematically
removing waste and reducing variation. It combines lean manufacturing/lean enterprise and Six Sigma to
eliminate the eight kinds of waste (muda): Defects, Over-Production, Waiting, Non-Utilized Talent,
Transportation, Inventory, Motion, and Extra-Processing
1
.
Lean Six Sigma is used to reduce process defects and waste, and to provide a framework for overall
organizational culture change. Through the introduction of Lean Six Sigma, employers hope to change the
mindset of employees and managers to one that focuses on growth and continuous improvement through
process optimization. This change in culture and the mindset of an organization can potentially maximize
efficiency and increase profitability

.
Why is it important to hold a Lean Six Sigma certification?
Holding a Lean Six Sigma certification proves the candidate's proficiency with Lean Six Sigma methodology,
beyond the mere knowledge of terminology. It shows to employers that the candidate has the potential to be
the person they need to cover The Certified Yellow Belt, The Certified Green Belt or The Certified Black Belt role
in their teams.
Whether the candidate is a beginner or a seasoned professional, a certification is a significant advantage when
aiming to motivate and lead teammates. The Lean Six Sigma credential showcases that the candidate has the
skills necessary to achieve the desired results, such as defect reduction, process improvement or any other
strategically aligned organizational objectives.
1.1. Lean Six Sigma Qualification Scheme
The Lean Six Sigma qualification scheme has been structured as follows:
Lean Six Sigma Yellow Belt (16 training hours) Candidates get the essential knowledge needed for the
foundational elements of the Lean Six Sigma Methodology and a good understanding of the elementary
aspects of the Lean Six Sigma Method including competence in the subject matters contained within the
phases of Define, Measure, and Control (DMC).
Lean Six Sigma Green Belt (80 training hours) Candidates will enhance on all aspects of the core to
advanced elements of Lean Six Sigma Methodology and get an in-depth understanding of all aspects of the
Lean Six Sigma Method including higher competence in subject matters contained within the phases of
Define, Measure, Analyze, Improve and Control (DMAIC).

Lean Six Sigma Black Belt (120 training hours) Candidates will enhance on all aspects of the advanced
elements of Lean Six Sigma Methodology and get a thorough understanding of all aspects of the Lean Six
Sigma Method including advanced competence in subject matters contained within the phases of Define,
Measure, Analyze, Improve and Control (DMAIC).
The IASSC Lean Six Sigma Yellow Belt certification, by PeopleCert covers the fundamental elements required
for a candidate to build their knowledge and skills regarding the Lean Six Sigma Methodology.
The body of knowledge underlying these skills are presented in the official courseware provided by PeopleCert
to accredited ATOs. The primary purpose of the syllabus is to provide a basis for accreditation of people
involved with the Lean Six Sigma Methodology. It documents the learning outcomes related to the
qualification and describes the requirements a candidate is expected to meet to demonstrate that these
learning outcomes have been achieved at the specific qualification level.

3.1. Qualification Scheme Level
Through the above learning objectives, candidates will demonstrate relevant knowledge skills in the following
phases:
Main Topics
Define Phase
Measure Phase
Control Phase
4. Examination
The Lean Six Sigma Yellow Belt exam focuses on the following four (4) categories in the cognitive domain of
Bloom’s Taxonomy- Revised (2001) model
2
which is a reference for different levels of learning:
Remember
Understand
Apply
Analyze
The IASSC Lean Six Sigma Yellow Belt certification, by PeopleCert exam is designed to target a cognitive level up
to Analyze.
4.1. Assessment Approach
The assessment approach used for the IASSC Lean Six Sigma Yellow Belt certification, by PeopleCert focuses
on the four cognitive levels of remember, understand, apply, analyze. Those are listed below from the least
complex to the most complex:
Remember: Recall or recognize terms, definitions, facts, ideas, materials, patterns, sequences, methods,
principles, etc.
Understand: Read and understand descriptions, communications, reports, tables, diagrams, directions,
regulations, etc.
Apply: Know when and how to use ideas, procedures, methods, formulas, principles, theories, etc.
Analyze: Break down information into its constituent parts and recognize their relationship to one another and
how they are organized; identify sub-level factors or salient data from a complex scenario.
2
The Bloom's taxonomy defines six (6) levels of learning in the cognitive domain (remember, understand, apply, analyze, evaluate, create),
which are both sequential and cumulative and move from the simple to the complex.
In order to achieve the 6th level of learning, it must be ensured that the previous five levels have been mastered.
