Performance

Performance is the execution of a task, action, or function, or the public presentation of an artistic work. It is used across disciplines to describe how well something achieves its intended objectives.

In human terms, performance refers to physical or cognitive capabilities and the outcomes of practice, training, and motivation. Assessments consider speed, accuracy, endurance, consistency, and quality. Performance enhancement typically involves deliberate practice, feedback, rest, and proper technique.

In the performing arts, performance denotes the realization of a work by performers before an audience, emphasizing interpretation, technique, timing, and communication.

In business and organizations, performance describes outcomes such as productivity, quality, profitability, and customer satisfaction, relative to goals. Organizations measure performance using indicators and frameworks like dashboards or the balanced scorecard, and use performance management to align strategies, resources, and activities.

In computing and engineering, system performance refers to responsiveness and capacity. Common metrics include latency, throughput, response time, resource utilization, reliability, and scalability. Performance testing and profiling identify bottlenecks and guide optimization.

Performance research notes that metrics must be interpreted in context; comparisons require normalization and consideration of external factors. The term also appears in performance metrics standards and governance, including service level agreements and reliability targets.
