1. The primary role of a Master Black Belt within an organization is to:
A. Lead individual DMAIC projects
B. Train and mentor Black Belts and Green Belts
C. Collect process data
D. Facilitate Kaizen events only
Answer: B
Master Black Belts focus on strategy, governance, coaching, and capability
building rather than project execution.
2. Which statistical concept is most critical for validating complex
experimental results at the MBB level?
A. Mean comparison
B. Correlation
C. Hypothesis testing with confidence intervals
D. Run charts
Answer: C
Confidence intervals and hypothesis testing support decision-making under
uncertainty at advanced levels.
3. In advanced Design of Experiments (DOE), aliasing primarily occurs due to:
A. Measurement error
, B. Confounding of factors
C. Random variation
D. Lack of replication
Answer: B
Aliasing results when factor effects are confounded, common in fractional factorial
designs.
4. An enterprise-wide Lean Six Sigma deployment should be aligned most
closely with:
A. Departmental goals
B. Individual KPIs
C. Organizational strategy
D. Operational metrics only
Answer: C
Strategic alignment ensures projects deliver measurable business value.
5. Which financial metric is MOST appropriate for validating project benefits at
the executive level?
A. Cycle time reduction
B. Defects per million opportunities (DPMO)
C. Net present value (NPV)
D. Process capability index (Cpk)
Answer: C
NPV translates improvement into financial impact understood by leadership.
6. Control limits on a control chart are primarily determined by:
A. Customer requirements
B. Specification limits
, C. Process variation
D. Operator judgment
Answer: C
Control limits reflect natural process variation, not customer specs.
7. Which Lean principle focuses on eliminating unevenness and overburden?
A. Kaizen
B. Heijunka
C. Jidoka
D. Poka-Yoke
Answer: B
Heijunka levels workload to reduce waste and instability.
8. When mentoring Black Belts, an MBB should prioritize which competency?
A. Tool memorization
B. Statistical software usage
C. Critical thinking and problem framing
D. Report formatting
Answer: C
MBBs develop thinking capability, not just technical skill.
9. A process shows high Cp but low Cpk. This indicates:
A. Excessive variation
B. Poor data collection
C. Process is off-center
D. Stable and capable process
, Answer: C
High Cp with low Cpk means the process spread is acceptable but not centered
within specs.
10.Which approach best supports sustaining improvements across multiple
sites?
A. Local work instructions
B. Standardized global processes
C. Individual incentives
D. Ad-hoc audits
Answer: B
Standardization enables scalability and consistency.
11.At the MBB level, system dynamics is MOST useful for:
A. Root cause analysis
B. Modeling complex organizational interactions
C. Control chart interpretation
D. Error proofing
Answer: B
System dynamics helps analyze feedback loops and long-term effects.
12.The primary purpose of a governance model in Lean Six Sigma deployment
is to:
A. Approve training materials
B. Control statistical methods
C. Ensure accountability and alignment
D. Track attendance
Answer: C
Governance structures maintain discipline and strategic focus.
