The paper presents a methodology for the evaluation of the economic impact of metrology in manufacturing. Cost-benefit analyses are carried out in order to evaluate costs and benefits; while the evaluation of costs is straightforward, the quantification of benefits is a complex task, due to the nature, of benefits such as improvement of product reliability and related reduction of warranty costs. %26lt;br%26gt;The evaluation methodology is based on a probabilistic approach and designed in view of its practical use as a decision support system. It requires input data from design, testing, manufacturing and inspection activities, as well as information on discard or rework costs, loss of production and warranty costs. The model is illustrated using an industrial case study.
