In this paper two major additions to the Goal/Question/Metric (GQM) method are presented based on seven years of experience with goal-oriented measurement programs. GQM, is a method to organize software measurement programs. The initial ideas of GQM were first published in 1984 and, since then, much industrial experience has been gained and theory has been developed to underpin the approach. The two additions concern a thorough elaboration of the feedback of measurement data and a conjunct cost/benefit analysis of the GQM project. The first addition refers to establishing conditions that are necessary to facilitate learning in software measurement programs. Learning about software quality is identified as the most important objective of a measurement program. The second addition refers to identifying whether the measurement program was actually worthwhile. Through a cost/benefit analysis the software measurement activity is brought in perspective with the other business objectives. Case study research illustrates the importance of both additions. In the past seven years we have been involved in fifteen measurement programs in five industrial organizations. Successes and failures in these organizations support the importance of both additions. The two additions: feedback sessions and cost/benefit analysis are described in detail in this article.
