Yellow Belt Body of Knowledge

The IASSC Universally Accepted Lean Six Sigma Body of Knowledge (ILSSBOK) is an embodiment of the consensus of what industry expects of a Lean Six Sigma Black Belt, Lean Six Sigma Green Belt and a Lean Six Sigma Yellow Belt.

The ILSSBOK is the result of research that was conducted over a two year period with the assistance of the leading industry publication house, Open Source Six Sigma. The goal of this project was to characterize the standard knowledge requirements that are universally expected of a Lean Six Sigma Black Belt, Lean Six Sigma Green Belt and a Lean Six Sigma Yellow Belt. With input from 1000′s of Deployment Leaders, Master Blacks Belts, Black Belts and Green Belts from 100′s of companies and industry sectors the ILSSBOK is truly the Voice of the Industry.

This is a significant breakthrough, for the first time in the history of the Lean Six Sigma the industry itself as a whole has defined what it deems is as a relevant and practical version of the knowledge expectations of a Lean Six Sigma Black Belt, Green Belt and Yellow Belt. Today, IASSC continues this research and accepts ongoing industry feedback to ensure the standards continue to accurately represent the market expectations.

The ILSSBOK consists of five primary sections each of which is broken into sub-categories. This Body of Knowledge serves as the basis for what many of today’s leading Lean Six Sigma companies consider to be standard and expected knowledge requirements of a Lean Six Sigma Black Belt, Lean Six Sigma Green Belt and Lean Six Sigma Yellow Belt. This body of knowledge also serves as the foundation upon which IASSC Certification examinations are built.

The IASSC Certified Yellow Belt Exam was developed and constructed based on the topics within the body of knowledge listed here. Questions may test up to the complexity level of “Apply” as defined by Levels of Cognition based on Bloom’s Taxonomy – Revised (2001). More about Blooms Taxonomy may be found in the FAQ’s section.

Levels of Cognition based on Bloom’s Taxonomy – Revised (2001)

These levels are from “Levels of Cognition” (from Bloom’s Taxonomy – Revised, 2001). They are listed in order 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 sublevel factors or salient data from a complex scenario.

Evaluate: 
Make judgments about the value of proposed ideas, solutions, etc., by comparing the proposal to specific criteria or standards.

Create: 
Put parts or elements together in such a way as to reveal a pattern or structure not clearly there before; identify which data or information from a complex set is appropriate to examine further or from which supported conclusions can be drawn.
