Lean Six Sigma Yellow Belt Certification Define Phase Deliverables 4 — Questions and Answers
Question 1: Which Define phase deliverable captures the team's agreed-upon definition of what constitutes a defect for the project?
- Defect definition / operational definition (Correct answer)
- Control plan
- Measurement system analysis
- Response surface map
Correct answer: Defect definition / operational definition
An operational definition of a defect ensures all team members consistently identify and count defects the same way.
Question 2: The 'S' in SIPOC stands for:
- Scope
- Specification
- Suppliers (Correct answer)
- Standards
Correct answer: Suppliers
SIPOC begins with Suppliers — the entities that provide inputs to the process.
Question 3: A team charter differs from a project charter in that a team charter primarily addresses:
- The financial ROI of the project
- Team roles, responsibilities, and ground rules for working together (Correct answer)
- The statistical tools to be used in the Analyze phase
- Customer complaint data and VOC findings
Correct answer: Team roles, responsibilities, and ground rules for working together
A team charter defines how the team will operate, including roles, norms, and decision-making processes.
Question 4: During Define, the project sponsor's primary role is to:
- Collect and analyze process data
- Champion the project, remove barriers, and ensure resource availability (Correct answer)
- Develop the measurement plan
- Conduct root cause analysis workshops
Correct answer: Champion the project, remove barriers, and ensure resource availability
The sponsor (Champion) provides leadership support, removes organizational obstacles, and secures resources for the team.
Question 5: Which statement about the Define phase is most accurate?
- Solutions are identified and piloted during Define
- Define establishes what problem is being solved and why it matters before data collection begins (Correct answer)
- Statistical analysis is the primary activity in Define
- Control plans are developed and implemented in Define
Correct answer: Define establishes what problem is being solved and why it matters before data collection begins
Define sets the foundation by clarifying the problem, scope, and goals before moving into Measure and subsequent phases.
Question 6: A Voice of the Customer (VOC) collection method that gathers data from customers in their natural environment is called:
- Benchmarking
- Ethnographic research / gemba observation (Correct answer)
- Design of experiments
- Regression analysis
Correct answer: Ethnographic research / gemba observation
Ethnographic research or gemba observation involves going to where customers interact with the product/service to observe needs firsthand.
Question 7: In the Define phase, 'scope creep' refers to:
- An increase in process sigma level beyond the target
- Uncontrolled expansion of the project's boundaries beyond what was agreed upon (Correct answer)
- A gradual increase in defect rate during measurement
- The addition of new team members midway through the project
Correct answer: Uncontrolled expansion of the project's boundaries beyond what was agreed upon
Scope creep occurs when the project gradually expands beyond its defined boundaries, risking timelines and resources.
