Metrics and Lessons Learned for Object-Oriented Projects

In the past decade , many companies have started to deploy objected-oriented (OO) technology in their software development efforts. Object-oriented analysis (OOA), object-oriented design (OOD), and object-oriented languages and programming (OOP) have gained wide acceptance in many software organizations. OO metrics have been proposed in the literature and there have been increased discussions in recent years . In this chapter we discuss the major OO metrics in the literature, and give examples of metrics and data from commercial software projects. We attempt to discuss the metrics from several perspectives including design and complexity, productivity, and quality management. In the last part of the chapter, we discuss the lessons learned from the assessments of a good number of the OO projects over the past decade.
