1. Q1.A quality council reviews four completed improvement projects:
   
   $$\begin{array}{l|c|c} \textbf{Team} & \textbf{Annual savings} & \textbf{Project cost} \\ \hline \text{Alpha} & \$120{,}000 & \$40{,}000 \\ \text{Bravo} & \$90{,}000 & \$25{,}000 \\ \text{Charlie} & \$150{,}000 & \$60{,}000 \\ \text{Delta} & \$70{,}000 & \$14{,}000 \end{array}$$
   
   Which team achieved the highest return on the resources invested?

   • A.Alpha
   • B.Bravo
   • C.Charlie
   • D.Delta✓ Correct answer

   Explanation

   Return on investment is net benefit divided by cost:
   
   $$\text{Alpha} = \frac{80}{40} = 2.0 \quad \text{Bravo} = \frac{65}{25} = 2.6 \quad \text{Charlie} = \frac{90}{60} = 1.5 \quad \text{Delta} = \frac{56}{14} = 4.0$$
   
   Charlie returns the largest absolute saving and Delta the smallest, which is why ranking on savings alone gives the wrong answer.

2. Q2.A project manager has the following activity network:
   
   $$\begin{array}{l|c|c} \textbf{Activity} & \textbf{Predecessor} & \textbf{Duration (days)} \\ \hline \text{A} & \text{none} & 4 \\ \text{B} & \text{A} & 6 \\ \text{C} & \text{A} & 3 \\ \text{D} & \text{B} & 5 \\ \text{E} & \text{C} & 9 \\ \text{F} & \text{D and E} & 2 \end{array}$$
   
   What is the shortest possible project duration?

   • A.15 days
   • B.17 days
   • C.18 days✓ Correct answer
   • D.29 days

   Explanation

   Evaluate both paths and take the longer one:
   
   $$A\!-\!B\!-\!D\!-\!F = 4+6+5+2 = 17 \qquad A\!-\!C\!-\!E\!-\!F = 4+3+9+2 = 18$$
   
   The critical path is A-C-E-F at 18 days. An answer of 29 sums every activity as though none ran in parallel.

3. Q3.A team tallies 500 defects found over one month:
   
   $$\begin{array}{l|c} \textbf{Defect} & \textbf{Count} \\ \hline \text{Scratches} & 260 \\ \text{Misalignment} & 140 \\ \text{Wrong label} & 50 \\ \text{Short fill} & 30 \\ \text{Other} & 20 \end{array}$$
   
   Applying the Pareto principle, which categories should the team address?

   • A.Scratches only
   • B.Scratches and misalignment✓ Correct answer
   • C.Scratches, misalignment, and wrong label
   • D.All five categories

   Explanation

   Cumulate the counts until roughly 80 percent of the total is covered:
   
   $$\frac{260 + 140}{500} = 80\%$$
   
   Adding wrong label reaches 90 percent, which is past the vital few and spreads the team's effort across a category worth a tenth of the problem.

4. Q4.A company applies the same audit frequency to all two hundred of its suppliers.
   
   What is the most significant weakness of this approach?

   • A.Low-risk suppliers are audited more than necessary
   • B.Audit resources are not directed according to risk✓ Correct answer
   • C.The audit program costs more than was budgeted
   • D.Suppliers receive inconsistent feedback on findings

   Explanation

   A uniform schedule spends the same effort on a stationery supplier as on the source of a safety-critical part, which leaves the important exposures underexamined. Cost is a symptom of the same misallocation rather than the weakness itself.

5. Q5.A service level agreement is reported for the quarter:
   
   $$\begin{array}{l|c|c} \textbf{Commitment} & \textbf{Target} & \textbf{Achieved} \\ \hline \text{Acknowledge within 4 hours} & 95\% & 99\% \\ \text{First response within 1 day} & 90\% & 94\% \\ \text{Resolve within 5 days} & 85\% & 62\% \\ \text{Escalate within 2 days} & 90\% & 91\% \end{array}$$
   
   What is the customer most likely to experience?

   • A.Prompt attention that does not lead to resolution✓ Correct answer
   • B.A service that performs well on every commitment
   • C.Slow initial response followed by fast resolution
   • D.Consistent performance across all four commitments

   Explanation

   Three commitments about responding are met or exceeded and the one about actually fixing the problem misses by 23 points. Fast acknowledgment raises the expectation that resolution will follow, so failing on nearly four cases in ten is felt more sharply for having been answered quickly.
