Metric

A metric is a quantifiable measure used to assess, compare, and track performance or progress. It provides a standardized method for evaluating different aspects of a system, process, or entity. In essence, a metric assigns a numerical value to an observed phenomenon, enabling objective analysis and informed decision-making. Metrics can encompass various domains, including science, engineering, business, and everyday life, helping to gauge efficiency, effectiveness, and the overall health of a subject. They provide benchmarks and facilitate improvements by allowing comparison against established standards, historical data, or other entities. A metric typically involves data collection, analysis, and interpretation, contributing to a more data-driven understanding. Properly chosen metrics are aligned with the goals being pursued and provides a more complete perspective. A metric is a single unit. Metrics are gathered to make decisions based on information provided, creating more educated decisions based on more objective data.
