3 Software To measure is to know. (Maxwell) You cannot control what you cannot measure. (DeMarco) A science is as mature as its measurement tools. (Pasteur) Software metrics are used to characterize the essential features of software quantitatively, so that classification, comparison, and mathematical analysis can be applied. (Conte) How many metrics should we use? Metrics should be easy to understand, easy to use etc.
