Final answer:
A factory manager should use a product defect queue to manage cases related to product quality issues. The defect group members are added to this queue to efficiently address and resolve product defects. This helps in measuring quality control and improving production processes.
Step-by-step explanation:
To manage cases effectively using queues, a factory manager should typically use a product defect queue. This type of queue is designed to prioritize and organize issues related to product defects, and allows the team responsible for defect management, commonly referred to as the defect group, to address them efficiently. The members of the defect group are added to this queue so they can triage, assign, and resolve product defects as they are reported.
In this scenario, the queue helps the manager understand the ratio of defective products to the total number produced by tracking the number of cases in the queue. It is crucial for the accurate measurement of quality control and production efficacy. Moreover, by analyzing data from the queue, the manager can also identify trends in defects and potentially implement improvements in the production process to reduce the number of defects over time.
