Metrics: A set of measurements to track product development and allow a firm to measure the impact of process improvements over time. These measures generally vary by firm but may include measures characterizing both aspects of the process, such as time to market, and duration of particular process stages, as well as outcomes from product development such as the number of products commercialized per year and percentage of sales due to new products.
度量:一套跟踪产品开发的测量方法，允许公司对流程推进带来的影响进行衡量的测量方法。这些方法因公司而异，包括流程的特征测试，如投放时间、具体开发时间、每年新产品商业化的结果和新产品的销售比重等等。
