Although refactoring does not add features or functionalities in a software system, it is sharp weapon for developers in their maintenance activities. It makes a software system easier to understand and cheaper to modify without changing its observable behavior by changing its internal structure.

The purposes of refactoring according to Martin Fowler (Father of Code Smell) are stated in the following:

  1. Refactoring Improves the Design of Software
  2. Refactoring Makes Software Easier to Understand
  3. Refactoring Helps Finding Bugs
  4. Refactoring Helps Programming Faster

Specially for long-term software, it is essential to refactor the code in order to make the software more adaptive. However, you definitely do not perform refactoring tasks, if it exceeds your budget and time. In essence, stop refactoring when you -

  1. Run out of money
  2. Run out of time
