Lean Six Sigma Yellow Belt Certification Lean Six Sigma Yellow Belt Define Phase Deliverables 1 — Questions and Answers
Question 1: Which Define phase tool is used to identify and prioritize customer needs by translating VOC data into specific, measurable product or process requirements?
- Quality Function Deployment (QFD) / House of Quality (Correct answer)
- Failure Mode and Effects Analysis (FMEA)
- Control Chart
- Fishbone Diagram
Correct answer: Quality Function Deployment (QFD) / House of Quality
QFD (also called the House of Quality) is the Define phase tool that systematically translates VOC data into measurable Critical-to-Quality (CTQ) requirements, bridging customer language and process specifications.
Question 2: In the Define phase, what is the main purpose of a Stakeholder Analysis?
- To calculate the financial savings of the project
- To identify individuals or groups impacted by the project and plan for their engagement (Correct answer)
- To map the current-state process flow in detail
- To define the root cause of the problem
Correct answer: To identify individuals or groups impacted by the project and plan for their engagement
Stakeholder Analysis identifies all parties affected by or influential to the project, enabling the team to plan appropriate communication and change management strategies throughout the project.
Question 3: A project scope statement in the Define phase serves primarily to:
- List all possible root causes of the defect
- Define what is included in and excluded from the project boundaries (Correct answer)
- Identify the statistical tools that will be used in the Analyze phase
- Document the final process improvements to be implemented
Correct answer: Define what is included in and excluded from the project boundaries
The scope statement clearly delineates project boundaries — what processes, locations, products, or time periods are in scope and which are explicitly excluded — preventing scope creep and keeping the team focused.
Question 4: Which of the following best describes a 'Critical to Quality' (CTQ) characteristic in the Define phase?
- A high-level financial metric used by executive sponsors
- A measurable product or process feature that directly impacts customer satisfaction (Correct answer)
- A list of team members assigned to quality control tasks
- A Gantt chart milestone for the project schedule
Correct answer: A measurable product or process feature that directly impacts customer satisfaction
CTQs are specific, measurable characteristics of a product or process that directly determine whether the customer's needs are met. They are derived from VOC data and become the focus of improvement efforts.
Question 5: What is the role of a Project Sponsor (Champion) as identified during the Define phase?
- To perform detailed data collection and statistical analysis
- To provide organizational authority, resources, and remove barriers for the project team (Correct answer)
- To map the detailed current-state value stream
- To conduct all customer interviews for VOC collection
Correct answer: To provide organizational authority, resources, and remove barriers for the project team
The Champion or Sponsor is a senior leader who authorizes the project, secures funding and resources, helps remove organizational obstacles, and ensures alignment with business strategy — not day-to-day project work.
Question 6: During the Define phase, a SIPOC diagram is typically created at what level of process detail?
- A highly detailed step-by-step flowchart with decision points and rework loops
- A high-level overview showing four to seven major process steps (Correct answer)
- A statistical control chart showing process variation over time
- A value stream map with cycle times and inventory counts at each step
Correct answer: A high-level overview showing four to seven major process steps
SIPOC is intentionally a high-level tool — typically four to seven major process steps — designed to give all stakeholders a shared understanding of the process scope before detailed analysis begins.
