CPIM - Manage Quality, Continuous Improvement, and Technology Example Questions

Test your knowledge of Manage Quality, Continuous Improvement, and Technology

Question 1

A company uses barcode scanning at its warehouse but frequently experiences inventory count errors. The team wants to adopt a technology that allows automatic tracking of items as they move through receiving, storage, and shipping areas. Which emerging technology should they implement?

Correct Answer: RFID tags and readers placed at key transition points throughout the warehouse

RFID (Radio Frequency Identification) tags and readers enable automatic, hands-free tracking of inventory as items pass through key transition points such as receiving, storage, and shipping, eliminating the need for manual line-of-sight scanning and significantly reducing count errors.

Blockchain records transactions but does not physically track item movements through a warehouse. IoT temperature sensors monitor environmental conditions, not item location or movement. Advanced barcode scanners still require manual, line-of-sight operation and do not provide the automatic tracking capability the company needs.

The key concept tested is the application of RFID technology for automated inventory tracking and improved warehouse accuracy.

Question 2

A team finds that operators at a packaging station frequently stop working because they run out of labels, which are delivered in large batches once per shift. The team wants to apply a lean approach to solve this issue. What should the team implement?

Correct Answer: A kanban-based replenishment system that signals when labels need restocking in smaller, more frequent deliveries

A kanban-based replenishment system directly addresses the root cause by using a pull signal to trigger smaller, more frequent deliveries of labels, preventing stockouts at the packaging station and eliminating operator downtime.

A visual management board only tracks and displays data but does not actively trigger replenishment, so it would not solve the supply interruption. A weekly batching system with safety stock contradicts lean principles by increasing batch sizes and relying on inventory buffers rather than flow. Assigning a dedicated operator to monitor inventory adds non-value-added labor and relies on a push-based, time-interval approach rather than actual consumption signals.

The key concept tested is kanban pull-based replenishment as a lean tool to ensure continuous material flow.

Question 3

A team at a manufacturing plant notices that each operator performs the same task differently, leading to varying product quality. The team leader wants to apply TQM principles to address this. What should the team do?

Correct Answer: Document and standardize the best-known method, then train all operators on it

A core TQM principle is reducing process variation by standardizing work methods, so documenting the best-known method and training all operators ensures consistency and improved quality at the source.

Assigning an experienced operator to inspect finished products relies on detection rather than prevention, which contradicts TQM philosophy. Collecting control chart data on individual operators monitors variation but does not eliminate the root cause of inconsistency. Establishing a suggestion program for individual preferred techniques would perpetuate variation rather than reduce it.

The key concept tested is process standardization as a foundation of Total Quality Management to reduce variation and build quality into the process.
