Lean Six Sigma Green Belt Certification Lean Six Sigma Green Belt Define Phase Concepts Questions and Answers 2 — Questions and Answers
Question 1: Which tool is used in the Define phase to translate customer needs into specific, measurable requirements?
- Critical to Quality (CTQ) tree (Correct answer)
- Fishbone diagram
- Control chart
- Pareto chart
Correct answer: Critical to Quality (CTQ) tree
A CTQ tree translates broad customer needs into specific, measurable critical-to-quality requirements that the project must address.
Question 2: What does SIPOC stand for in the context of the Define phase?
- Suppliers, Inputs, Process, Outputs, Customers (Correct answer)
- Standards, Inputs, Procedures, Outcomes, Controls
- Suppliers, Issues, Process, Objectives, Customers
- Scope, Inputs, Parameters, Outputs, Constraints
Correct answer: Suppliers, Inputs, Process, Outputs, Customers
SIPOC is a high-level process map that identifies Suppliers, Inputs, Process steps, Outputs, and Customers to define project boundaries.
Question 3: A project charter states that defect rates must decrease from 8% to 2% within six months. Which element of the charter does this represent?
- Goal statement (Correct answer)
- Business case
- Problem statement
- Project scope
Correct answer: Goal statement
The goal statement specifies the measurable target improvement the project aims to achieve, including the magnitude and timeline.
Question 4: Which Voice of the Customer (VOC) collection method provides the deepest qualitative insight into customer pain points?
- One-on-one interviews (Correct answer)
- Online surveys
- Complaint log analysis
- Focus groups
Correct answer: One-on-one interviews
One-on-one interviews allow probing follow-up questions that uncover deeper qualitative insights into individual customer experiences and pain points.
Question 5: What is the primary risk of defining the project scope too broadly during the Define phase?
- The project may exceed timeline and resource constraints (Correct answer)
- The team will lack sufficient data to analyze
- Stakeholders will disengage from the project
- The control phase becomes unnecessary
Correct answer: The project may exceed timeline and resource constraints
An overly broad scope leads to scope creep, causing the project to consume more time and resources than planned without delivering focused results.
Question 6: In stakeholder analysis during the Define phase, what is the recommended approach for a stakeholder with high influence but low support for the project?
- Manage closely and develop a targeted engagement strategy (Correct answer)
- Inform them periodically with status updates
- Exclude them from project communications
- Assign them as the process owner
Correct answer: Manage closely and develop a targeted engagement strategy
High-influence, low-support stakeholders can derail a project, so they require close management and a deliberate strategy to gain their buy-in.
