Costs of the legacy code

"To me legacy code is simply code without tests."
Michael C. Feathers “Working effectively with legacy code”

The legacy code is a known software developers’ headache. The legacy code is the difficult to change code that the developers don’t really understand. This code often is inherited from the old developers who left the company, it usually has little to no documentation and little to no testing code. Legacy code can slow down the development speed up to the real competitive problems. When it takes eternity to make a required change, a company can hardly stand a competitor that is able to release life-critical software every month.
