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.
