In software engineering, many reuse metrics and models are metrics used to measure code reuse and reusability.
A metric is a quantitative indicator of an attribute of a thing.
Reuse models and metrics can be categorized into six types: Reuse cost-benefits models include economic cost-benefit analysis as well as quality and productivity payoff.
Maturity assessment models categorize reuse programs by how advanced they are in implementing systematic reuse.
Failure modes analysis is used to identify and order the impediments to reuse in a given organization.
