Why refactoring may be necessary

There are several indicators that refactoring the existing software product or application may be necessary:

• One change causes many new defects
• More complex, structural changes take longer to implement
• Needed changes are perceived as too risky and not implemented

Refactoring involves restructuring an existing code base, making internal changes without changing external (functional) behavior.   Rigourous and disciplined refactoring approach is based on series of properly planned and executed small changes.  While each change (also called a 'refactoring') focused on a small and finite objective, the sum of these changes can produce substantial desired code transformation.  During refactoring, the application continues operate.   Automated unit, function, and regression tests help ensure that functionality is not impacted by refactoring efforts.
