1. Which of the following phases of the DMAIC methodology is focused on finalizing the
project charter and identifying stakeholders?
A. Define
B. Measure
C. Analyze
D. Improve
Rationale: The Define phase is the first step of DMAIC, where the problem
statement, goal statement, project charter, and stakeholders are formally identified
and established.
2. What is the main purpose of the Measure phase in a Six Sigma project?
A. To implement temporary fixes to the system
B. To establish a baseline for current process performance
C. To find the ultimate root causes of the problem
D. To roll out standard operating procedures
Rationale: The Measure phase focuses on collecting data to establish a reliable
baseline of current process performance so that improvement can be accurately
measured.
3. An AIGPE Certified Green Belt candidate is preparing for the exam. What is the total
number of questions on the official test?
A. 50 questions
B. 75 questions
C. 100 questions
D. 150 questions
1|Page
, Rationale: The official AIGPE Certified Six Sigma Green Belt examination consists of
exactly 75 multiple-choice questions.
4. To successfully clear the official AIGPE Six Sigma Green Belt certification exam,
what minimum percentage score must a student achieve?
A. 50%
B. 60%
C. 70%
D. 85%
Rationale: AIGPE requires a minimum passing score of 60%, which translates to
correctly answering 45 out of the 75 exam questions.
5. Which two DMAIC phases collectively account for approximately 55% of the
questions on the official AIGPE Green Belt exam?
A. Define and Control
B. Measure and Analyze
C. Improve and Control
D. Define and Improve
Rationale: The AIGPE curriculum places a heavy mathematical and diagnostic
emphasis on the Measure and Analyze phases, making up about 55% of the total
exam weight.
6. What type of tool is a SIPOC diagram, and in which phase is it most commonly
introduced?
A. A quantitative data tool used in Analyze
B. A high-level process map used in Define
C. A control plan checklist used in Control
D. A creative brainstorming tool used in Improve
Rationale: SIPOC (Suppliers, Inputs, Process, Outputs, Customers) is a high-level
process mapping tool used during the Define phase to understand project
boundaries.

,7. Which of the following is considered an open-book policy asset during the official
online AIGPE Green Belt examination?
A. Live consultation with an expert via chat
B. Your personal training notes and masterclass slides
C. Copying questions into a public forum for live answers
D. Utilizing a secondary person to take the test for you
Rationale: The AIGPE Green Belt exam is open-book, meaning you are allowed to
utilize your own training materials, notes, and masterclass downloads during the test.
8. What is the primary difference between a Six Sigma Green Belt and a Six Sigma
Black Belt?
A. Green Belts only work on financial auditing projects.
B. Black Belts work completely independent of company strategic goals.
C. Black Belts lead cross-functional projects full-time, while Green Belts lead
process-level projects part-time.
D. Green Belts do not need to understand any statistical tools or Minitab.
Rationale: Green Belts generally work on projects within their own functional areas
on a part-time basis, whereas Black Belts handle larger, enterprise-wide projects full-
time.
9. In a standard project charter, what does the "Problem Statement" describe?
A. The monetary budget allocated for team rewards
B. The exact solution that will be implemented next week
C. What is wrong, the impact it has, and where/when it occurs
D. The complete list of statistical tools to be used in Minitab
Rationale: A problem statement must clearly define the pain point, its operational or
financial impact, and its scope without assuming or stating the cause or solution.
10. Which statistical software is explicitly integrated into the AIGPE Green Belt
masterclass for data analysis?
A. SPSS
B. SAS
C. Minitab
D. Stata
3|Page
, Rationale: The AIGPE Green Belt training specifically incorporates Minitab Statistical
Software to teach students how to execute raw data analyses and hypothesis
testing.
11. What does the acronym VOC stand for in the context of Six Sigma Quality
Management?
A. Value of Control
B. Verification of Capability
C. Variance of Characteristics
D. Voice of the Customer
Rationale: VOC stands for Voice of the Customer, representing the explicit and
implicit needs, requirements, and feedback provided by the end-users.
12. When a Green Belt translates the Voice of the Customer (VOC) into measurable
process requirements, these requirements are called:
A. CTQs (Critical-to-Quality characteristics)
B. DPMOs (Defects Per Million Opportunities)
C. RTYs (Rolled Throughput Yields)
D. SPCs (Statistical Process Controls)
Rationale: Critical-to-Quality (CTQ) parameters are the internal critical, measurable
metrics derived directly from external customer requirements (VOC).
13. What is a "Defect" as defined by Six Sigma methodology?
A. Any process step that takes more than 10 minutes to finish
B. Any product or service characteristic that fails to meet customer
specifications
C. A breakdown of Minitab software during data calculation
D. An update to the project charter requested by the sponsor
Rationale: A defect is any instance or event where a product or service output fails to
meet an established customer specification limit.
14. If a process operates at a full Six Sigma level, how many defects per million
opportunities (DPMO) does it produce?
