Lean Six Sigma Yellow Belt Certification Lean Six Sigma Yellow Belt The Define Phase 1 — Questions and Answers
Question 1: In the Define phase, what is the primary method used to capture the Voice of the Customer (VOC)?
- Conducting statistical process control charts
- Gathering feedback through surveys, interviews, and focus groups (Correct answer)
- Performing a root cause analysis using fishbone diagrams
- Running designed experiments to test process variables
Correct answer: Gathering feedback through surveys, interviews, and focus groups
VOC is collected through direct customer engagement methods such as surveys, interviews, complaints, and focus groups. This raw customer input is then translated into measurable CTQs. Statistical tools and experiments are used in later DMAIC phases.
Question 2: Which of the following best describes the purpose of a project scope statement in the Define phase?
- To identify the root causes of the process defect
- To define the boundaries of what the project will and will not address (Correct answer)
- To quantify the financial savings expected from the project
- To assign quality control checkpoints throughout the process
Correct answer: To define the boundaries of what the project will and will not address
The scope statement establishes clear in-scope and out-of-scope boundaries, preventing scope creep and keeping the team focused. Financial savings belong in the business case, and root cause analysis happens in the Analyze phase.
Question 3: What does a well-written goal statement in a Define phase project charter typically follow?
- The DMAIC framework
- SMART criteria (Specific, Measurable, Achievable, Relevant, Time-bound) (Correct answer)
- The 5S methodology
- The Pareto principle
Correct answer: SMART criteria (Specific, Measurable, Achievable, Relevant, Time-bound)
SMART criteria ensure the goal statement is clear, trackable, realistic, aligned with business needs, and has a deadline. Without these qualities, a goal statement cannot be objectively evaluated at the project tollgate.
Question 4: In Lean Six Sigma, who is typically responsible for removing organizational roadblocks and providing resources for a Yellow Belt project team?
- The Process Owner
- The Champion or Sponsor (Correct answer)
- The Black Belt
- The Quality Auditor
Correct answer: The Champion or Sponsor
The Champion or Sponsor is a senior leader who authorizes the project, secures resources, and removes barriers the team encounters. The Black Belt provides technical guidance, while the Process Owner manages day-to-day operations.
Question 5: During the Define phase, a team uses a Kano Model to analyze customer requirements. What does the Kano Model primarily help teams distinguish?
- The cost difference between value-added and non-value-added steps
- Basic must-have needs versus performance satisfiers versus delighters (Correct answer)
- The frequency of defects versus their severity
- Customer segments by geographic region
Correct answer: Basic must-have needs versus performance satisfiers versus delighters
The Kano Model categorizes customer needs into must-be requirements (basics), performance requirements (more is better), and attractive requirements (unexpected delighters). This helps teams prioritize which CTQs will have the greatest impact on customer satisfaction.
Question 6: At the end of the Define phase, the project team presents findings at a tollgate review. What is the key question the tollgate is designed to answer?
- Has the root cause of the problem been statistically confirmed?
- Is the problem clearly defined, scoped, and worth solving before moving to Measure? (Correct answer)
- Have all process improvements been piloted and validated?
- Has the control plan been implemented to sustain the gains?
Correct answer: Is the problem clearly defined, scoped, and worth solving before moving to Measure?
The Define phase tollgate confirms that the project is well-scoped, the problem is clearly articulated, the business case is justified, and the team is ready to proceed to Measure. Root cause confirmation and control plans are outputs of later phases.
