November 1, 2011 by Brent Sordyl 1 Comment

Size is the best predictor of code quality

September 26, 2011 by Brent Sordyl 0 Comments

A long paper trail of software engineering studies has shown that many internal code metrics (such as methods per class, depth of inheritance tree, coupling among classes etc.) are correlated with external attributes, the most important of which is bugs. What the authors of this paper show is that when they introduce a second variable, namely, the total size of the program, into the statistical analysis and control for it, the correlation between all these code metrics and bugs disappears.

Such a switch means discarding two decades of knowledge and expertise of Windows development—and countless hours spent learning Microsoft’s latest-and-greatest technology—and perhaps just as importantly, it means discarding rich, capable frameworks and the powerful, enormously popular Visual Studio development environment, in favor of a far more primitive, rudimentary system with substantially inferior tools.
