Lean Six Sigma Yellow Belt Certification Lean Six Sigma Yellow Belt The Improve Phase Questions and Answers 2 — Questions and Answers
Question 1: Which brainstorming technique involves writing ideas on sticky notes silently before group discussion?
- Brainwriting (Correct answer)
- Round-robin brainstorming
- Mind mapping
- Affinity diagramming
Correct answer: Brainwriting
Brainwriting has participants silently write ideas on sticky notes or cards before sharing, reducing groupthink and encouraging equal participation.
Question 2: What is the primary purpose of a pilot test during the Improve phase?
- To validate the proposed solution on a small scale before full implementation (Correct answer)
- To identify root causes of the problem
- To measure current process performance
- To create a project charter
Correct answer: To validate the proposed solution on a small scale before full implementation
A pilot test validates the proposed solution on a limited scale to confirm effectiveness and identify issues before a full rollout.
Question 3: In the Improve phase, what does a cost-benefit analysis help the team determine?
- Whether the expected benefits of a solution justify its implementation costs (Correct answer)
- The statistical significance of process data
- The voice of the customer requirements
- The current sigma level of the process
Correct answer: Whether the expected benefits of a solution justify its implementation costs
A cost-benefit analysis compares the projected financial benefits of a solution against its costs to ensure the improvement is economically justified.
Question 4: Which tool uses a structured ranking system to compare multiple solutions against weighted criteria?
- Pugh matrix (Correct answer)
- Pareto chart
- Control chart
- Fishbone diagram
Correct answer: Pugh matrix
A Pugh matrix (decision matrix) scores each potential solution against weighted criteria to objectively identify the best option.
Question 5: What is the role of a stakeholder analysis during solution implementation in the Improve phase?
- To identify who is affected by the change and plan appropriate communication and engagement (Correct answer)
- To calculate process capability indices
- To determine sample sizes for data collection
- To map the value stream of the process
Correct answer: To identify who is affected by the change and plan appropriate communication and engagement
Stakeholder analysis identifies individuals or groups impacted by the change so the team can address concerns and secure buy-in for successful implementation.
Question 6: What does FMEA stand for in the context of evaluating improvement solutions?
- Failure Mode and Effects Analysis (Correct answer)
- Functional Measurement and Evaluation Assessment
- Final Management Efficiency Audit
- Frequency Modulation Error Analysis
Correct answer: Failure Mode and Effects Analysis
Failure Mode and Effects Analysis is a systematic method for evaluating potential failure modes of a solution and their impact to proactively mitigate risks.
