Effects of the number of developers on code quality in open source software
Brandon Norick, Justin Krohn, Eben Howard, Ben Welna, Clemente I. Izurieta · 2010
Eleven open source software projects were analyzed to determine if the number of committing developers impacts code quality. We use cyclomatic complexity, lines of code per function, comment density, and maximum nesting as surrogate measures of code quality. We find no significant evidence to suggest that the number of committing developers affects the quality of software.
