Lean Six Sigma Yellow Belt Certification FREE Lean Six Sigma Yellow Belt Six Sigma Fundamentals Questions and Answers 2 — Questions and Answers
Question 1: What does the acronym DMAIC stand for in Six Sigma?
- Define, Measure, Analyze, Improve, Control (Correct answer)
- Design, Monitor, Assess, Implement, Check
- Develop, Manage, Audit, Inspect, Close
- Document, Map, Align, Integrate, Certify
Correct answer: Define, Measure, Analyze, Improve, Control
DMAIC stands for Define, Measure, Analyze, Improve, and Control, which is the core improvement methodology in Six Sigma.
Question 2: Which of the following best describes the concept of 'variation' in Six Sigma?
- The inconsistency or fluctuation in a process output (Correct answer)
- The total number of defects produced
- The speed at which a process operates
- The cost associated with running a process
Correct answer: The inconsistency or fluctuation in a process output
Variation refers to the inconsistency in process outputs that Six Sigma aims to reduce to improve quality.
Question 3: What is the primary goal of the 'Control' phase in DMAIC?
- To sustain the improvements made during the Improve phase (Correct answer)
- To identify the root cause of defects
- To collect baseline performance data
- To define the project scope and objectives
Correct answer: To sustain the improvements made during the Improve phase
The Control phase focuses on sustaining improvements by implementing monitoring systems and control plans.
Question 4: In Six Sigma, what does a 'CTQ' represent?
- Critical to Quality characteristic that customers care about most (Correct answer)
- Cost to Qualify metric for supplier evaluation
- Cycle Time Quotient for measuring process speed
- Compliance to Quota standard for production targets
Correct answer: Critical to Quality characteristic that customers care about most
CTQ stands for Critical to Quality and represents the key measurable characteristics of a product or process that must meet customer requirements.
Question 5: Which Six Sigma role is responsible for leading a project team and executing DMAIC on a specific problem?
- Green Belt (Correct answer)
- Yellow Belt
- Champion
- Master Black Belt
Correct answer: Green Belt
A Green Belt typically leads smaller Six Sigma projects and applies DMAIC methodology to solve specific problems.
Question 6: What does the sigma level of a process indicate?
- The capability of the process to produce outputs within specification limits (Correct answer)
- The total revenue generated by the process
- The number of employees required to run the process
- The age of the process since implementation
Correct answer: The capability of the process to produce outputs within specification limits
The sigma level measures how well a process performs relative to customer specifications, with higher sigma meaning fewer defects.
