Refactoring and reengineering software
If you find yourself in a situation where adding a trivial feature to the system takes an enormous amount of time, chances are that you need to refactor the system's code.
Today, refactoring is a necessary process that improves the design of a system and takes control of decaying code. It also improves readability and maintainability of existing code. If you find that your code becomes more difficult to maintain with every new change, then refactoring is your best option.
There are times when even refactoring falls short of reviving decaying code on a legacy system that is no longer able to scale to a constantly increasing load; in this case, the only option is reengineering the whole system to remove performance bottlenecks, improve the design of the system and assuage maintenance tasks.
In some cases, it is enough to change several algorithms to improve performance drastically, while in others the only way is to migrate the entire system to some new technology / programming language.
Reengineering almost always begins with refactoring. When the code is bad, it is impossible to reengineer it without refactoring it first, because it is only after that step that the conceptual design of the system starts to appear magically from the mess created by numerous hacks and spaghetti-code.
Refactoring and reengineering require good coverage of the system in question by automated unit-tests. Without them, it is almost impossible to tell whether some modifications preserve the existing behavior of a system or not. That is why a positive side effect of our refactoring and reengineering service is that you will have your system fully covered with automated unit-tests.
