In software engineering, many '''reuse metrics''' and [models](/source/Scientific_modelling) are metrics used to measure [code reuse](/source/code_reuse) and reusability. A metric is a [quantitative](/source/Quantitative_property) indicator of an attribute of a thing. A model specifies relationships among metrics. Reuse models and metrics can be categorized into six types:

# reuse cost-benefits models
# maturity assessment
# amount of [reuse](/source/reuse)
# failure modes
# [reusability](/source/reusability)
# reuse library metrics

Reuse cost-benefits models include economic [cost-benefit analysis](/source/cost-benefit_analysis) as well as quality and [productivity](/source/productivity) payoff. 
Maturity assessment models categorize reuse programs by how advanced they are in implementing systematic reuse.
Amount of reuse metrics are used to assess and monitor a reuse improvement effort by tracking percentages of reuse for life cycle objects. 
Failure modes analysis is used to identify and order the impediments to reuse in a given organization. 
Reusability metrics indicate the likelihood that an artifact is reusable. 
Reuse library metrics are used to manage and track usage of a reuse repository.
