Nothing is perfect, and there will always be room for improvement, even if you have created something pretty good. The same applies to technology and software engineering. In the fast-paced modern world, any business can keep up with constant changes and speed up to stay competitive. So eventually, business owners start to think about making their platform software even more efficient, modern, and flexible.
Meet software re-engineering.
In simple words, re-engineering is a process of altering software to modernize it. This process usually includes but is not limited to developing and implementing new features, adding more functionality, improving maintainability, etc. The primary goal of software re-engineering is to improve software and make it more efficient and effective. Re-engineering impacts cost, quality, and customer service in the long run; however, it can’t be regarded as an easy and quick process.
Key benefits of software re-engineering
Software re-engineering is an essential component of your product quality improvement. This process contributes to your business revenue and allows you to provide better services to your customers.
Re-engineering is the way to detect unnecessary elements in your current software and remove them from your system to make it more efficient and easier, and cheaper to maintain.
2. Increasing productivity.
Software re-engineering boosts the productivity of your business by optimizing the database and code so that processing becomes faster.
3. Risk reduction.
The chances of faults in software products are much higher when it has been developed from scratch. While re-engineering, developers start from a certain existing stage and bring in additional features or optimize a code.
Software re-engineering stages.
The Software re-engineering process typically consists of 3 main stages preceded by inventory analysis. These are reverse engineering, restructuring, and forward engineering.
Reverse engineering is a process of reproduction of any product after a detailed examination of its composition. Tools used in reverse engineering help extract data and architectural and design information from a given software product. Reverse engineering is quite helpful when the software product documentation is no longer available.
This stage is followed by code reconstructing. Developers analyze the source code using a reconstruction tool, then review and test the result to ensure no faults or anomalies are detected. An essential part of reconstruction is data restructuring. Data objects and attributes are identified during this process, and existing data structures are reviewed for quality.
The flow ends with forwarding to engineering, also called a renovation, integrating the changes and latest specifications to the product.
We described the most common model of software re-engineering. However, there is no specific Software development Life Cycle to follow for this process. The chosen model can vary to address business specifics and depending on the current environment.
The demand for software re-engineering is expected to grow as software gets out of date. To prevent various problems which might arise, companies should consider software re-engineering process initiation.
