Measures the level of output per worker; a measure of motivation because employees tend to be more productive with increased levels of motivation.

• A. Motivation
• B. Efficiency
• C. Productivity
• D. Output rate

Answer: (C)

Productivity is the measure of output per unit of input, such as output per worker. When you see “level of output per worker,” you’re looking at labor productivity—the amount each worker contributes. Motivation affects how much workers produce, so a higher motivation level tends to boost productivity, making it the most appropriate metric for this description. Motivation itself is about drive, not a measurement. Efficiency is about how well resources are used, not specifically about output per worker, and output rate refers to how fast production occurs rather than per-worker contribution.
