The software community of the 1980s was abuzz with seemingly endless approaches to producing higher-quality software. At the forefront was software metrics and its corresponding techniques, tools, and process-improvement schemes. Cyclomatic complexity, Halstead metrics, source lines of code (SLOC), Fagan inspection, defect counting, number of defects prediction, reliability estimation and model...
