Which of the following is a measure commonly used to assess performance?

Efficiency is a commonly used measure to assess performance because it directly relates to how well resources are utilized to achieve specific outcomes. In a law enforcement context, efficiency can reflect how effectively officers accomplish their duties, respond to situations, or handle cases relative to the resources available to them, including time, manpower, and equipment.

When evaluating an organization’s or an officer's performance, measuring efficiency provides insight into productivity and operational success. It helps identify strengths and weaknesses in processes and can guide improvements in service delivery. For instance, an officer who resolves cases quickly while utilizing minimal resources is demonstrating high efficiency. This metric allows for data-driven decision-making and improvements in law enforcement practices.

Other measures like quality, quantity, and time management can be components contributing to the overall efficiency but focusing solely on efficiency encapsulates the essence of performance in a brief, comprehensive manner.
