Lean Six Sigma Yellow Belt Certification Define Phase Deliverables 2 — Questions and Answers
Question 1: Which document formally authorizes a Lean Six Sigma project and grants the team permission to proceed?
- Process map
- Project charter (Correct answer)
- Control plan
- Cause-and-effect diagram
Correct answer: Project charter
The project charter is the formal authorization document that defines scope, goals, and resources, officially launching the project.
Question 2: In the Define phase, a SIPOC diagram is used primarily to:
- Identify root causes of defects
- Provide a high-level view of the process and its boundaries (Correct answer)
- Calculate process capability
- Determine optimal control limits
Correct answer: Provide a high-level view of the process and its boundaries
SIPOC maps Suppliers, Inputs, Process, Outputs, and Customers at a high level to define process scope and boundaries.
Question 3: The 'C' in SIPOC stands for:
- Controls
- Capability
- Customers (Correct answer)
- Constraints
Correct answer: Customers
SIPOC stands for Suppliers, Inputs, Process, Outputs, and Customers — the C represents those who receive the process output.
Question 4: Which of the following is NOT typically included in a project charter?
- Problem statement
- Root cause analysis (Correct answer)
- Project scope
- Business case
Correct answer: Root cause analysis
Root cause analysis occurs in the Analyze phase; the charter is completed in Define and does not yet identify causes.
Question 5: A well-written problem statement in the Define phase should:
- Identify the root cause and propose a solution
- Quantify the gap between current and desired performance without assigning blame (Correct answer)
- List all stakeholders and their responsibilities
- Define control limits for the process
Correct answer: Quantify the gap between current and desired performance without assigning blame
A good problem statement describes the issue with measurable terms and avoids presuming causes or solutions.
Question 6: Which Define phase deliverable identifies all individuals or groups who may affect or be affected by the project?
- Control plan
- Stakeholder analysis (Correct answer)
- Process capability report
- Response surface design
Correct answer: Stakeholder analysis
A stakeholder analysis identifies, categorizes, and plans engagement with everyone who has an interest in the project.
Question 7: The primary purpose of defining the project scope in the Define phase is to:
- Calculate the cost of poor quality
- Set clear boundaries on what the project will and will not address (Correct answer)
- Establish statistical significance thresholds
- Determine the measurement system accuracy
Correct answer: Set clear boundaries on what the project will and will not address
Defining scope prevents scope creep by clearly stating what is included and excluded from the project.
