Six Sigma Yellow Belt Certification Overview

A follow-on from the fundamental concepts of White Belt, focusing on the concepts, techniques, strategies and tools used to improve process efficiency, wasted efforts and resources leading to cost reduction. The course content and assignments review the DMAIC (Define, Measure, Analyze, Improve, Control) steps and deliverables in relation to the Toyota “Lean” methodology. With a focus on visual control and Non-value analysis, the participant learns to reduce wasted effort and materials.


As with the White Belt course, the students directly apply the tools and principles to a personal project. This class helps the students to work smarter and look at ways to solve processing issues in the corporate world


To build upon the students’ foundational Process Improvement knowledge learned in White Belt and focus the impact their attention on what is known as “waste” and the tools and techniques used to reducing its negative impact.

The exam specifically focuses on the students’ ability to identify the various types of waste and the tools used to address them. It specifically tests:

  • Time and Value from the customer’s perspective

  • The 8 types of waste (the Cii 9)

  • The “5s” method of waste reduction

  • The use of Six Sigma tools to enhance waste reduction

  • Value Added and Non-Value-Added analysis (VA and NVA)

  • Visual Management Methods

  • Kaizen event planning and execution

  • Integration of waste reduction into DMAIC projects (Low Hanging Fruit)


View the Yellow Belt Domain Objectives in more detail.

The overall objective of the classwork and project is to show the student the importance of:

  1. Supporting projects that are focused on improving operational efficiencies by reducing “waste” and costs using basic “Lean” management techniques

  2. Assisting Six Sigma Green Belts and Black Belts in data collection and analysis and process mapping and infusing “waste reduction” expertise into every process improvement effort

  3. Implementing Lean Enterprise tools, techniques and practices as a part of one’s regular duties to achieve cost reduction and operational efficiencies.
