The role of object-oriented metrics

The most common concern of project managers who use or who are about to use object technology is for more measurement tools. Some of these people would accept anything that could give some kind of quantitative grasp of the software development process. An extensive literature is even available on software metrics, including object-oriented development. The first rule of quantitative software evaluation is that numbers are collected and computed, there should be a specific intent related to understanding, controlling, or improving software and its production. This implies that there are two kinds of metrics: product metrics, which measure properties of software; and process metrics, which measure properties of the process used in the development.
