    Skills You Will BuildAcross the Five DMAIC Phases

    In this Lean Six Sigma Yellow Belt training you will learn to support real improvement projects using the DMAIC method and core Lean tools. The programme builds foundational, awareness-level skills mapped to the IASSC Yellow Belt Body of Knowledge.

    Define Projects That Matter

    Learn to frame an improvement project using voice of the customer, critical-to-quality characteristics, a project charter and SIPOC, so you can spot where a process is failing and why it is worth fixing.

    Measure Process Performance

    Build the Measure-phase basics: process mapping, simple descriptive statistics and core Six Sigma metrics such as DPU, DPMO, first-time yield and cycle time, so improvement is based on data, not opinion.

    Analyse Root Causes

    Use fishbone diagrams, Pareto analysis and an introduction to hypothesis testing to separate the real drivers of a problem from the noise and focus your effort where it counts.

    Improve and Reduce Waste

    Get an introduction to correlation and simple regression alongside Lean waste reduction, so you can support practical changes that streamline flow and lift quality.

    Control and Sustain Gains

    Apply control-phase tools including basic statistical process control, control plans and mistake-proofing so the improvements your team makes actually hold over time.

    Apply Core Lean Tools

    Put 5S, value stream mapping, Kanban and Poka-Yoke to work, the everyday Lean tools that keep workplaces organised, visual and efficient across manufacturing and services.

    Frequently Asked QuestionsHere's everything you may ask...

    The Lean Six Sigma Yellow Belt is the entry-level process improvement credential from IASSC. It validates foundational, awareness-level knowledge of the DMAIC method and core Lean tools, and is designed for team members who support improvement projects rather than lead them.

    General

    What is the Lean Six Sigma Yellow Belt certification?

    The Lean Six Sigma Yellow Belt is the entry-level process improvement credential from IASSC. It validates foundational, awareness-level knowledge of the DMAIC method and core Lean tools, and is designed for team members who support improvement projects rather than lead them.

    Is the Lean Six Sigma Yellow Belt worth it in Bulgaria?

    Yes. Bulgaria's automotive, electronics, manufacturing and shared-services employers run lean, high-volume operations and value staff who can support quality and efficiency projects. A Yellow Belt is a recognised first step toward quality, operations and continuous improvement roles.

    Who should take this course?

    It suits front-line staff, team members, supervisors and anyone new to process improvement across manufacturing, BPO, logistics, healthcare and IT. No prior experience is needed, so it is a strong first credential before progressing to Green Belt.

    Do I need any prerequisites?

    No. There are no prerequisites for the Yellow Belt; training and work experience are recommended but not required. Anyone can enrol and sit the exam, which makes it an accessible entry point into Lean Six Sigma.

    How long is the certification valid?

    The Yellow Belt certification is valid for three years. To keep it current you pass the recertification exam before the three-year period elapses, so your credential stays recognised by employers.

    What is the difference between Yellow, Green and Black Belt?

    Yellow Belt is the foundational level, giving awareness of DMAIC and Lean tools to support project teams. Green and Black Belts go deeper into statistics and project leadership. Yellow Belt is the natural starting point on that path.

    The exam is closed book with 60 multiple-choice and true/false questions, based on the Yellow Belt Body of Knowledge and structured around the five DMAIC phases. It is taken under proctored conditions.

    How long is the exam and what is the pass mark?

    You have two hours to complete the 60 questions, and you need a minimum of 230 points out of 300 to pass. Some exam forms add up to six unscored pretest questions that do not count toward your score.

    What happens if I do not pass the first time?

    You can retake the exam by purchasing another voucher. Our training includes practice questions and mock tests aligned to the 60-question format to help you prepare thoroughly and pass with confidence.

    What is the exam application process?

    You purchase an exam voucher through the official IASSC ordering portal, choose online proctored or test-centre delivery, then schedule and sit the 60-question exam. On passing, you receive a certificate, a digital badge and a listing in the certification register.
