Effects of the number of developers on code quality in open source software: a case study
Eleven open source software projects written in C/C++ were analyzed to determine if the number of committing developers impacts code quality. We use cyclomatic complexity, lines o...

An Empirical Study of Software Reuse vs. Defect-Density and Stability
The paper describes results of an empirical study, where some hypotheses about the impact of reuse on defect-density and stability, and about the impact of component size on defec...
