Actual output divided by effective capacity
Design capacity divided by actual output

Correct answer: Actual output divided by design capacity

Utilization rate = Actual output / Design capacity, expressing how much of the theoretical maximum capacity is actually being used.

Question 5: A company uses ABC analysis for inventory classification. 'A' items are best described as:

Low-cost items purchased in bulk to minimize ordering frequency
High-value items representing a small percentage of SKUs but large portion of spend (Correct answer)
Items with the most frequent stockouts and reorder events
Items with the highest number of SKUs in the warehouse

Correct answer: High-value items representing a small percentage of SKUs but large portion of spend

ABC analysis classifies 'A' items as those representing roughly 80% of total inventory value despite being only about 20% of total SKUs, warranting tightest control.

Question 6: A remote operations team is experiencing communication breakdowns. Which intervention is MOST effective?

Establishing structured communication protocols and regular check-ins (Correct answer)

Mean Absolute Percentage Error (MAPE)
Mean Squared Error (MSE) (Correct answer)
Mean Absolute Deviation (MAD)
Tracking signal

Correct answer: Mean Squared Error (MSE)

MSE squares each error before averaging, giving disproportionately higher weight to large errors compared to linear error metrics.

Question 25: Which of the following is a key difference between 'common cause' variation and 'special cause' variation in process management?

Special cause variation is inherent in the system; common cause is due to unusual events
Both types require the same response from management
Common cause variation is random and systemic; special cause variation is due to identifiable, assignable factors (Correct answer)
Common cause variation requires immediate corrective action; special cause does not

Correct answer: Common cause variation is random and systemic; special cause variation is due to identifiable, assignable factors
