Which term best describes the phenomenon where performance improves with increased experience?

The term that best describes the phenomenon where performance improves with increased experience is the experience curve. This concept suggests that as individuals or organizations repeat tasks, they become more proficient over time due to accumulated knowledge, skills, and efficiencies gained from experience. The experience curve reflects a direct relationship between the number of times a process is completed and the efficiency achieved, ultimately leading to improved performance.

The experience curve is widely applicable in various fields, including manufacturing and service industries, where repetitive tasks allow workers to refine their techniques, streamline processes, and reduce error rates. Over time, this results in cost savings, increased speed, and overall enhancement in output quality.

In contrast, the other terms do not accurately capture this relationship. An efficiency curve typically focuses on the relationship between output and inputs in terms of resource utilization but does not inherently consider the aspect of learning through experience. A motivation curve may refer to the relationship between motivation levels and performance but does not specifically address the improvement resulting from experience. Meanwhile, a productivity curve generally relates to output per unit of input, without a direct reference to the benefits accruing from increased experience. Thus, the experience curve is the most appropriate term to describe this specific phenomenon.
