Lean Six Sigma Yellow Belt Certification Define Phase Deliverables 3 — Questions and Answers
Question 1: Which element of the project charter describes the financial or strategic reason for undertaking the project?
- Goal statement
- Problem statement
- Business case (Correct answer)
- Project timeline
Correct answer: Business case
The business case explains why the project is worth pursuing in terms of financial impact or strategic alignment.
Question 2: Voice of the Customer (VOC) data collected in the Define phase is most directly used to:
- Set control chart limits
- Identify Critical-to-Quality (CTQ) characteristics (Correct answer)
- Calculate process sigma level
- Develop the control plan
Correct answer: Identify Critical-to-Quality (CTQ) characteristics
VOC data is translated into CTQs, which define measurable quality requirements from the customer's perspective.
Question 3: A project goal statement in the Define phase should be:
- Vague to allow flexibility during the project
- SMART: Specific, Measurable, Achievable, Relevant, and Time-bound (Correct answer)
- Focused on assigning blame for the problem
- Written after root causes are identified
Correct answer: SMART: Specific, Measurable, Achievable, Relevant, and Time-bound
SMART goal statements ensure the project has a clear, quantifiable target with a defined timeline.
Question 4: In a SIPOC diagram, 'Inputs' refer to:
- The final products delivered to the customer
- Materials, information, or resources that enter the process (Correct answer)
- The steps taken to measure process performance
- The defect rate observed in the output
Correct answer: Materials, information, or resources that enter the process
Inputs are the materials, data, or resources supplied by suppliers that are transformed by the process.
Question 5: Which tool used in the Define phase visually shows the team's project schedule and key milestones?
- Fishbone diagram
- Gantt chart (Correct answer)
- Control chart
- Scatter diagram
Correct answer: Gantt chart
A Gantt chart displays project tasks against a timeline, helping the team track milestones and deadlines.
Question 6: A 'quick win' identified during the Define phase is best described as:
- A solution requiring significant capital investment
- A small, immediate improvement that can be implemented without full DMAIC completion (Correct answer)
- The final control mechanism established at project close
- A statistical hypothesis requiring validation
Correct answer: A small, immediate improvement that can be implemented without full DMAIC completion
Quick wins are simple, low-risk improvements identified early that can be implemented immediately to build momentum.
Question 7: Which of the following best describes a CTQ (Critical to Quality) characteristic?
- A defect rate calculated from historical data
- A measurable process feature that directly impacts customer satisfaction (Correct answer)
- The number of process steps that add no value
- A control limit derived from statistical analysis
Correct answer: A measurable process feature that directly impacts customer satisfaction
CTQs are measurable product or process attributes that are critical to satisfying customer requirements.
