,Section 1: Organization-Wide Planning and Deployment
Question 1. Which of the following best describes the primary purpose of Hoshin Kanri (X-matrix) in
Six Sigma deployment?
A. To track individual project financial returns
B. To align strategic objectives with tactical initiatives across the organization
C. To replace the need for project charters
D. To calculate process capability indices
Correct Answer: B
Rationale: Hoshin Kanri (policy deployment) uses the X-matrix to cascade strategic goals into actionable
initiatives, ensuring alignment between long-term objectives and day-to-day projects. It is a strategic
planning and deployment tool, not a financial tracking or capability calculation method.
Question 2. An organization is deploying Six Sigma across multiple business units. Executive
leadership wants to ensure that improvement projects are strategically aligned. Which tool should be
used to prioritize projects based on strategic impact and resource requirements?
A. Control chart
B. Portfolio analysis
C. Gage R&R
D. Pareto chart
Correct Answer: B
Rationale: Portfolio analysis helps organizations evaluate and prioritize improvement projects based on
strategic alignment, resource availability, risk, and expected return. Control charts and Gage R&R are
operational tools, and Pareto charts prioritize defects, not projects.
Question 3. A Black Belt is developing a business case for a Six Sigma project. The project is expected
to reduce defects by 50%, saving $200,000 annually. The project will require $50,000 in resources. What
is the return on investment (ROI) for this project?
A. 25%
B. 75%
C. 300%
D. 400%
Correct Answer: C
Rationale: ROI = (Net Benefit / Cost) × 100. Net benefit = $200,000 − $50,000 = $150,000. ROI =
($150,000 / $50,000) × 100 = 300%.
, Question 4. Which of the following is a leading indicator of customer loyalty in a balanced scorecard
framework?
A. Customer retention rate
B. Customer satisfaction score
C. Number of customer complaints
D. Market share
Correct Answer: B
Rationale: Customer satisfaction is a leading indicator because it predicts future loyalty and retention.
Retention rate and market share are lagging indicators, and complaint counts reflect past performance.
Question 5. During strategic deployment, an organization conducts a SWOT analysis. Which of the
following would be classified as a "threat"?
A. A new internal training program
B. A competitor introducing a disruptive technology
C. Strong brand recognition
D. Limited internal expertise in statistical analysis
Correct Answer: B
Rationale: A threat is an external negative factor. A competitor's disruptive technology is an external
threat. Limited internal expertise is a weakness (internal), strong brand recognition is a strength, and a
training program is an internal action.
Question 6. Which of the following best describes the role of a Champion in a Six Sigma
deployment?
A. Performing day-to-day statistical analysis
B. Removing organizational barriers and securing resources for projects
C. Leading the project team in DMAIC execution
D. Auditing project documentation for compliance
Correct Answer: B
Rationale: Champions are senior leaders who sponsor projects, secure resources, and remove barriers.
Black Belts lead project execution, and statistical analysis is typically performed by Black Belts or Green
Belts.
Question 7. An organization is experiencing resistance to Six Sigma deployment from middle
management. Which change management technique would be most effective to address this?
A. Ignoring resistance and proceeding with projects
B. Conducting stakeholder analysis and readiness assessments
, C. Escalating all resistant managers to executive leadership
D. Reducing the scope of Six Sigma to avoid conflict
Correct Answer: B
Rationale: Stakeholder analysis and readiness assessments help identify sources of resistance and
develop targeted communication and engagement plans. Ignoring resistance or escalating without a
plan is ineffective.
Question 8. Which of the following is a key characteristic of a mature Six Sigma deployment?
A. Projects are selected ad hoc without strategic alignment
B. Six Sigma is integrated into daily operations and leadership accountability
C. Only Black Belts are involved in improvement activities
D. Financial benefits are not tracked
Correct Answer: B
Rationale: Maturity in Six Sigma deployment means the methodology is embedded in the organization's
culture, with leadership accountability and integration into daily work. Ad hoc project selection and
limited involvement indicate lower maturity.
Question 9. A company is evaluating whether to use Six Sigma or a simpler problem-solving
approach for a minor process issue. Which criterion would most strongly favor using Six Sigma?
A. The problem is well-understood and has a known solution
B. The problem is complex, chronic, and requires data-driven root cause analysis
C. The problem affects only one department
D. The solution can be implemented in one week
Correct Answer: B
Rationale: Six Sigma is best suited for complex, chronic problems requiring rigorous data analysis and
cross-functional solutions. Simple, well-understood problems may be addressed with basic problem-
solving tools.
Question 10. Which of the following is an example of a Key Behavior Indicator (KBI) in a Six Sigma
deployment?
A. Number of defects per million opportunities
B. Percentage of leaders conducting monthly project reviews
C. Process cycle time
D. Cost of poor quality
