Which metric is used most directly to assess labor efficiency?

• A. Forecast accuracy.
• B. Overtime hours.
• C. Labor cost percentage.
• D. Labor productivity (sales per labor hour).

Answer: (D)

Measuring how effectively labor turns time into output is the core idea here. Labor productivity, expressed as sales per labor hour, directly links the amount of output to the labor input. It shows how much revenue is produced for each hour of work, so improvements manifest as more sales per hour or the same sales with fewer hours.

Forecast accuracy is about predicting demand, not how efficiently labor is being used once demand is known. Overtime hours indicate extra hours worked, but they don’t by themselves reveal how productive those hours are. They can reflect high demand or poor scheduling, but they don’t measure output per hour. Labor cost percentage relates labor costs to sales, which is influenced by pricing and margins as well as efficiency, so it’s a less direct measure of how effectively labor is utilized.

Therefore, the most direct metric for labor efficiency is labor productivity.
