Six Sigma Yellow Belt Certification Questions And Answers

Question 1:
When a process has proven itself to function at a Six Sigma level, this means there are less than how many defects per million opportunities?

A. 1.7
B. 2.6
C. 3.4
D. 10

Correct Option: C. 3.4
A Six Sigma process aims for near-perfect quality, allowing no more than 3.4 defects per million opportunities.

Question 2:
Six Sigma refers to a process whose output has at least 95% of its data points within 6 standard deviations from the mean.

A. True
B. False

Correct Option: B. False
Six Sigma actually requires 99.99966% of data points to fall within 6 standard deviations from the mean, not just 95%. (95% corresponds to roughly 2 sigma.)

Question 3:
Training cost is $3,000 and a project requires an initial investment of $12,000. If the project yields monthly savings of $1,800 beginning after 3 months, what is the payback period in months (before money costs and taxes)?
A. 4.17
B. 8.33
C. 11.33
D. 28.28

Correct Answer: C. 11.33

The payback period is 11.33 months, including the 3-month delay before savings start.

Question 4:
The ROl for a project is a measurement metric that stands for Return on Investment and is one of the methods used to measure the success of a Lean Six Sigma project.

A. True
B. False

Correct Option: A. True
ROI (Return on Investment) is a key financial metric used to evaluate the efficiency and success of a Lean Six Sigma project by comparing net benefits to costs.

Question 5:
The DMAIC approach to problem solving stands for Define, _, Analyze, Improve and Control.

A. Manage
B. Measure
C. Memorize
D. Manipulate

Correct Option: B. Measure
The DMAIC methodology represents Define, Measure, Analyze, Improve, and Control – the five phases of Six Sigma process improvement.

Question 6:
Voice of the Customer is a Lean Six Sigma technique to determine the _ attributes of a product or service.

A. Desirable
B. Beneficial
C. Critical-to-Quality
D. Preferred

Correct Option: C. Critical-to-Quality (CTQ)
Voice of the Customer analysis identifies Critical-to-Quality (CTQ) characteristics – the key measurable requirements that directly impact customer satisfaction.

(Key distinction: While all options relate to customer needs, CTQ specifically refers to the quantifiable standards used in Six Sigma.)

Question 7:
Benefits and working conditions would be primarily the concern of which of the following?

A. Voice of the Customer
B. Voice of the Employee
C. Voice of the Business
D. Voice of the Process

Correct Option: B. Voice of the Employee
Benefits and working conditions directly address employee needs and satisfaction, making them central to the Voice of the Employee (VoE) perspective.

(Key Insight: While VoC focuses on customers and VoB on business goals, VoE specifically captures workforce concerns like benefits and workplace environment.)

Question 8:
In the expression Y = f(Xₙ), Y (the output) is the _ variable, and Xₙ (the inputs) are the _ variables.

A. Independent, dependent
B. Individual, multiple
C. Sole, multiple
D. Dependent, independent

Correct Option: D. Dependent, independent
In Six Sigma and process modeling:

  • Y (output) = Dependent variable (depends on the inputs)
  • Xₙ (inputs) = Independent variables (factors that influence Y)

(Key Concept: This reflects the cause-and-effect relationship central to process improvement, where outputs depend on controllable inputs.)

Question 9:
When we assess the Voice of the Customer, we are attempting to determine the gaps in our processes between “what is” and:

A. “What isn’t”
B. “What will make money”
C. “What will cost less”
D. “What should be”

Correct Option: D. “What should be”
Voice of the Customer (VOC) analysis identifies gaps between:

  • Current state (“what is”)
  • Desired state (“what should be” based on customer needs and expectations).

(Key Insight: This comparison drives process improvements to align outputs with customer requirements, a core Six Sigma principle.)

(Note: Options A, B, and C are irrelevant to VOC’s purpose of closing performance gaps against customer expectations.)

Question 10:
Which of the following would likely not be a CTQ (Critical-to-Quality) for the purchase of a product?

A. Functionality
B. Durability
C. Dependability
D. None

Correct Option: D. None
All options (Functionality, Durability, Dependability) are valid CTQs as they directly impact customer satisfaction. Thus, none can be excluded.
