In [[software]], '''metrics''' (most commonly referred to in plural) are: |
|||
* measurable characteristics of a system in development, e.g. a computer program or a software product, used for research and control in order to improve a company's work processes, or even the state of the art of software development as a whole (metrics studied as part of academic research projects) |
|||
* or, well-defined characteristics used to determine the performance and suitability of a production system, i.e. a software product in actual operation; such metrics are used to monitor the behaviour of the product for evaluation purposes (over periods of time, and/or against competing products) |

See [[software metric]]s for the first meaning of the concept. |

In [[mathematics]], a '''metric''' (also called '''distance metric''') is an abstraction of the notion of ''distance''; it is used to define [[metric space]]s. The article on [[metric space]]s contains a detailed discussion of the topic. |

In [[music]], ''metric'' and ''metrical'' refer to [[meter (music)]]. '''Metric structure''' includes meter, [[tempo]], and all [[rhythm]]ic aspects which produce temporal regularity or structure, against which the foreground details or [[durational pattern]]s are projected (DeLone et. al. (Eds.), 1975, chap. 3). |

[[Rhythmic unit]]s be metric, intrametric, contrametric, or extrametric. |

'''Metric level'''s may be distinguished. The [[beat level]] is the metric level at which pulses are heard as the basic time unit of the piece. Faster levels are [[division level]]s, and slower levels are [[multiple level]]s. (DeLone et. al. (Eds.), 1975, chap. 3). |

A [[metric modulation]] is a [[modulation]] from one metric unit or meter to another. |
