Q1. The supervisor asked the team to ______ the readings before submitting the report because one value appeared unusually high.

Q2. Choose the option that BEST completes the relationship - Calibration: Accuracy :: Maintenance: ______

Q3. Read the passage and answer the question that follows: A plant shifted its daily production review from the end of the shift to the middle of the shift. Supervisors could then identify material shortages and staffing gaps several hours earlier. After six weeks, total output remained almost unchanged, but overtime reduced and fewer orders required last-minute rescheduling. Managers decided to continue the mid-shift review and monitor its longer-term impact. Which conclusion is BEST supported by the passage?

Q4. The manager's explanation was ______; it addressed the immediate issue but left the underlying cause unclear.

Q5. Choose the option that BEST completes the relationship:Blueprint : Construction :: Schedule : ______

Q6. Read the passage and answer the question that follows: A supplier offered a component at a price 6% below the existing source. After three months, however, the plant found greater variation in dimensions, leading to additional inspection and rework. Although the purchase price was lower, the total cost per usable component was slightly higher. The sourcing team therefore decided to review quality, logistics, and processing costs before renewing the contract. Which conclusion is BEST supported?

Q7. The data were ______ the team's initial assumption that defects were evenly distributed across all shifts.

Q8. Choose the option that BEST completes the relationship: Symptom : Diagnosis :: Variance : ______

Q9. Read the passage and answer the question that follows: A manufacturing unit introduced cross-training so technicians could work on more than one assembly line. During the first month, output fell slightly because employees spent time learning unfamiliar tasks. Four months later, absenteeism caused fewer production disruptions because trained employees could move between lines when needed. Management concluded that the early productivity loss had to be considered alongside the later improvement in flexibility.What is the BEST inference?

Q10. The proposal was not rejected; the decision was ______ until the team could provide evidence from a wider range of operating conditions.

Q11. Choose the option that BEST completes the relationship: Tolerance : Dimension :: Budget: ______

Q12. Read the passage and answer the question that follows: An engineering team proposed automating a manual inspection process after a successful trial. The trial, however, had been conducted on only one product variant and during a period of unusually stable production. Management did not reject the proposal but asked for evidence from additional variants and operating conditions before approving the investment. The team was asked to extend the trial before presenting its final recommendation. Why did management request a wider trial?

Q13. One month of improved performance may ______ the team's hypothesis, but it cannot by itself establish that the new process caused the improvement.

Q14. Choose the option that BEST completes the relationship: Prototype : Product :: Pilot : ______

Q15. Read the passage and answer the question that follows: A plant recorded a sharp fall in defects soon after introducing a new inspection checklist. At the same time, a major supplier changed its manufacturing process and the plant increased operator training. Because all three changes occurred within the same period, managers agreed that the improvement was encouraging but could not confidently attribute the lower defect rate to the checklist alone. Which statement BEST reflects the managers' reasoning?

Q16. The two reports are not necessarily contradictory; their findings may be ______ because one describes average performance while the other focuses on peak-hour variation.

Q17. Choose the option that BEST completes the relationship: Average : Variation :: Summary : ______

Q18. Read the passage and answer the question that follows: Two departments reported apparently different conclusions about machine performance. Maintenance found that average downtime had fallen during the quarter, while production reported more frequent short stoppages during peak hours. A joint review showed that both statements were correct: long breakdowns had reduced, but brief interruptions had increased. Management decided that the measures captured different aspects of performance and should be reviewed together. What is the BEST conclusion?

Q19. The evidence does not invalidate the proposal, but it does ______ the claim that the improvement can be attributed solely to the new process.

Q20. Choose the option that BEST completes the relationship:Standardisation : Consistency :: Redundancy : ______

Q21. Read the passage and answer the question that follows:A pilot production cell achieved 12% higher output than the existing line. The pilot, however, handled a narrower product mix, used experienced operators, and received priority maintenance support. Management viewed the result positively but questioned whether the same gain would continue after full-scale implementation. Before approving expansion, it requested a trial under conditions closer to those expected in normal plant operations.Which inference is MOST justified?

Q57. A line shows good average output for the week, but hourly data reveal repeated periods of overproduction followed by waiting. Finished inventory between two processes is increasing, yet the final dispatch volume has not improved. What is the MOST appropriate interpretation?

Q58. A customer proposes shifting part of its business to the plant if the company develops a customized component. The projected margin is attractive, but the design will use scarce engineering capacity also needed for an existing platform launch carrying contractual penalties for delay. What should management do?

Q59. A manager needs support from Procurement for a cost-reduction project, but Procurement's current priority is supplier localization. The manager has no authority over the Procurement team. Both initiatives use the same limited supplier-development resources. What is the BEST approach?

Q60. A recurring defect disappears after both a machine setting and a supplier batch are changed on the same day. The team wants to close the problem because rejection has returned to normal. No controlled test has been performed. What should the manager do?

Q61. A strategic customer offers a five-year contract with guaranteed base volume but requires a significant price reduction from year three. The business case is attractive only if planned automation delivers the expected productivity gain. The automation is technically feasible but has not yet been implemented at this scale. Which decision approach is MOST robust?

Q62. A plant-wide cost program requires Operations, Quality and Engineering to change long-established practices. Each function supports the overall target but believes most changes should come from the other two. Previous meetings ended with broad agreement but little action. What should the program leader do NEXT?

Q63. A plant is considering raising a line's speed by 8% to recover a persistent delivery backlog. Trials show higher output, but also a small rise in temperature variation and two downstream stations operating close to capacity. Customer specifications are still being met during the trial. What should the operations manager do BEFORE making the higher speed permanent?
