A metric is a standard unit of measure, such as
meteror gram, or more generally, part of a system of parameters, or systems of measurement, or a set of ways of quantitatively and periodically measuring, assessing, controlling or selecting a person, process, event, or institution, along with the procedures to carry out measurements and the procedures for the interpretation of the assessment in the light of previous or comparable assessments.
Metrics are usually specialized by the subject area, in which case they are valid only within a certain domain and cannot be directly benchmarked or interpreted outside it. This factor severely limits the applicability of metrics, for instance in comparing performance across domains. The prestige attached to them may be said to relate to a 'quantifiability fallacy', the erroneous belief that if a conclusion is reached by quantitative measurement, it must be vindicated, irrespective of what parameters or purpose the investigation is supposed to have.
Examples include academic metrics such as an academic journal's
impact factorand bibliometrics; crime statistics; corporate investment metrics, such as earnings per shareor Price-to-earnings ratio; economic metrics or economic indicators, such as gross domestic productand the Gini coefficient, which are the subject of econometrics; education metrics, such as grade point average, standardized testscores such as the SATand College and university rankings; environmental or sustainability metrics and indices; health metrics, such as mortality rateand life expectancy; market metrics such as the Q score; political metrics, such as the United States Presidential approval rating; software metrics; and vehicle metricssuch as miles per gallon. In business, they are sometimes referred to as key performance indicators, such as overall equipment effectiveness, or key risk indicators. In the field of Facilities Management, a key metric is the Facility Condition Index, or FCI.
