ALBARRAQ has expertise in methods for reusing legacy software, restructuring it to make the code more understandable, and reengineering the system to handle new requirements. We can also manage a software system that demands constant change and growth - "constant" may even mean daily management of changes to the architecture and design, rather than just "one-shot" reengineering at the beginning of a traditional product development cycle.

Through software re-engineering, source code and/or data is modified to make it amenable to future changes. The re-engineering focuses on the design details of individual modules and on local data structures defined within modules.

With a similar goal to all reengineering activities, re-factoring is the process of changing a software system in such a way that it does not alter the external behavior of the code yet it improves its internal structure. Re-factoring makes the code easier to understand and cheaper to modify without changing its observable behavior.
