The DMAIC methodology

The structured problem-solving framework at the heart of this exam

The CSSYB BoK is built around the five DMAIC phases. This course teaches each phase from the ground up — no prior Six Sigma experience required.

D
Define

Identify the problem, define the project scope, and understand the voice of the customer

M
Measure

Collect data, analyse baseline performance, and assess measurement system capability

A
Analyze

Identify root causes of defects using tools like FMEA, 5 Whys, and process mapping

I
Improve

Implement solutions using kaizen, PDCA, and cost-benefit analysis

C
Control

Sustain improvements with control charts, control plans, and standard operating procedures

Sound familiar?

Four challenges every CSSYB candidate faces

This course is built to solve all four.

01

Six Sigma concepts feel abstract without real context

DPMO, rolled throughput yield, FMEA risk priority numbers, GR&R — without practical worked examples, these concepts stay theoretical and fail to stick under exam conditions.

02

The Analyze phase covers the most diverse topics

With 17 questions spanning FMEA, root cause tools, distributions, hypothesis testing, regression, and correlation, Analyze is the broadest section in the BoK — and the easiest to under-prepare for.

03

No explanations for wrong answers

Practising without understanding why you got something wrong leaves critical gaps. You need detailed reasoning behind every correct answer — especially for statistical questions and scenario-based items.

04

Studying alone is harder than it looks

When you're new to Six Sigma and hit a difficult concept — FMEA severity scoring, hypothesis test interpretation, control chart selection — there's nobody to ask. A study community keeps you moving forward.

What you'll master

Complete Body of Knowledge coverage

Mapped directly to all five sections of the 2022 CSSYB Body of Knowledge.

Describe the purpose of Six Sigma (reducing variation) and lean (waste elimination) and their value to an organisation
Identify Six Sigma roles (Yellow Belt, Green Belt, Black Belt, MBB, champion, sponsor) and team dynamics
Select and apply all seven basic quality tools: Pareto charts, cause-and-effect diagrams, flowcharts, histograms, scatter diagrams, check sheets, and run charts
Calculate and apply Six Sigma metrics: DPU, DPMO, rolled throughput yield (RTY), cycle time, and cost of poor quality (COPQ)
Define voice of the customer (VOC), CTQ characteristics, and use SIPOC to map process inputs and outputs
Calculate and interpret mean, median, mode, standard deviation, range, and variance
Describe MSA concepts: precision, accuracy, bias, linearity, stability, and gauge repeatability and reproducibility (GR&R)
Apply FMEA to identify potential failures using severity, occurrence, and detection to calculate the risk priority number (RPN)
Distinguish between common and special cause variation, and describe normal, binomial, skewed, and bimodal distributions
Apply kaizen, PDCA, and cost-benefit analysis in the Improve phase; sustain gains with control charts, control plans, and SOPs

Who it's for

You're in the right place if…

Professionals new to Six Sigma

You've heard of Six Sigma and want a structured, credential-backed introduction to DMAIC tools and methodology — no prior knowledge needed.

Entry-level quality and operations staff

You work in manufacturing, healthcare, or services and want a recognised ASQ certification that validates your quality knowledge at the foundational level.

Managers and champions seeking an overview

You sponsor or support Six Sigma projects and want to understand the DMAIC framework and quality metrics your team uses — without going to Green or Black Belt level.

Exam re-takers

You have attempted the CSSYB before and need a more structured, practice-focused approach — particularly on FMEA, statistics, and the Analyze phase.

Anyone building a Six Sigma foundation

Whether or not you plan to progress to Green Belt, this course gives you a complete, practical understanding of the DMAIC problem-solving methodology.

"I had zero Six Sigma background when I started. Sandeep explains DMAIC from the ground up — by the time I got to the practice questions, the concepts finally made sense. Passed the CSSYB on my first attempt."

A
Aaron P.
Operations Coordinator, Healthcare
★★★★★

"The 250+ practice questions with explanations are worth the price alone. I used them to drill every section, and the explanations helped me understand why my wrong answers were wrong — which is exactly what you need for this exam."

S
Sunita M.
Quality Analyst, Manufacturing
★★★★★

"The FMEA and metrics sections were the parts I was most worried about. Sandeep's step-by-step approach to RPN calculation and DPMO made them click. Great course for anyone starting out in Six Sigma."
