Abstract
This paper investigates if Code-Churn, Lines of Code (LoC), Duplicated Code, Complexity and Technical Debt (TD) can inform a coder where to prioritize refactoring. A mature code-base of 1 300 000 LoC in approximately 5000 files for a period of 20 months has been examined. The result is that code-churn is the strongest variable out of the studied variables followed by LoC and TD. Multiplying with code-churn strengthens LoC and TD even more, making them the strongest indicators of refactoring potential.
