Q1.
A process improvement team is selecting a project. Which tool best prioritizes projects
based on both impact and feasibility, considering the voice of the customer and business
objectives?
A. Pareto Chart B. Project Charter
C. Kano Model D. Project Selection Matrix
Correct: D - Project Selection Matrix
Rationale:A Project Selection Matrix (e.g., a weighted criteria matrix) systematically
evaluates projects against multiple criteria like impact, feasibility, and alignment, enabling
objective prioritization. Pareto Chart prioritizes causes, Kano Model categorizes customer
requirements, and Project Charter defines a selected project.
Q2.
In the Measure phase, a Green Belt calculates the measurement system's %GRR as 25%.
The process is a key characteristic. What is the most appropriate interpretation and
action?
A. The measurement system is marginally B. The measurement system is
acceptable; proceed with process analysis. unacceptable; improve it before using data
for decisions.
C. The measurement system is excellent; D. The measurement system is acceptable
no action needed. only for variables, not attributes.
Correct: B - The measurement system is unacceptable; improve it before using data for
decisions.
Rationale:According to AIAG guidelines, %GRR above 30% is generally unacceptable,
10-30% may be acceptable depending on application and cost, but for a key characteristic,
25% is too high and the system must be improved. A is too lenient, C is incorrect, D is
irrelevant.
Q3.
A process has a mean of 50 and standard deviation of 5. The spec limits are 40 and 60.
Assuming normality, what is the estimated process capability index (Cpk) and the
approximate percentage of nonconforming parts?

A. Cpk = 0.67; 4.5% nonconforming B. Cpk = 1.00; 0.27% nonconforming
C. Cpk = 1.33; 0.006% nonconforming D. Cpk = 0.33; 15.9% nonconforming
Correct: A - Cpk = 0.67; 4.5% nonconforming
Rationale:Cpk = min[(USL-mean)/(3Ã), (mean-LSL)/(3Ã)] = min[(60-50)/15, (50-40)/15] =
0.67. The nonconforming fraction is P(X<40) + P(X>60) = P(Z<-2) + P(Z>2) = 0.0228 +
0.0228 = 0.0456, about 4.5%. Other options have incorrect Cpk or nonconforming
percentages.
Q4.
In the Analyze phase, a Green Belt uses a two-sample t-test to compare the mean cycle
times of two shifts. The p-value is 0.04. Which conclusion is most appropriate at a 95%
confidence level?
A. There is strong evidence that the means B. There is no evidence of a difference
are different. because the p-value is not below 0.01.
C. The result is inconclusive; need to check D. The means are the same because the
normality. p-value is above 0.05.
Correct: A - There is strong evidence that the means are different.
Rationale:With ±=0.05, a p-value of 0.04 is less than ±, leading to rejection of the null
hypothesis of equal means, thus strong evidence of a difference. B is wrong because is not
0.01; C is not required for t-test robustness; D is opposite.
Q5.
A Green Belt is applying lean principles to reduce lead time. Which combination of tools is
most effective for identifying and eliminating waste in a value stream?
A. 5S, Kanban, and Poka-Yoke B. Value Stream Mapping, Spaghetti
Diagram, and Kaizen
C. SMED, TPM, and 5S D. Fishbone Diagram, FMEA, and Control
Charts
Correct: B - Value Stream Mapping, Spaghetti Diagram, and Kaizen
Rationale:VSM identifies waste and flow, Spaghetti Diagram reveals motion waste, and
Kaizen drives continuous improvement. 5S/Kanban/Poka-Yoke are improvement tools but not
primary for waste identification; SMED/TPM are specific; Fishbone/FMEA/Control Charts are
for problem-solving and control, not lean waste identification.
