What is Software Reengineering
So what should you do when you did something and you feel like you already did good? Should you just stop? Should you continue to do the same thing? You may prefer to say ‘Yes’ which is not that bad at all. But in the technological world, it is not easy to stop. In a fast and constantly changing world, your business needs to keep up, accelerate even. As far as satisfaction goes, it would be a waste to stop your pursuit to be better. So when you feel like you’ve already engineered a good software, platform, or business, what should you do next? Simple. REENGINEER!
Let’s Talk about Software Engineering
Before we begin discussing about software reengineering, let us get to software engineering first. Software engineering is a discipline of engineering that is concerned with the design, development, testing, maintenance, and deployment of a software product. These preceding aspects are part of the Software Development Life Cycle (SDLC) that a software undergoes before finally made available for client and users. Given that information, we can now discuss what Software Reengineering is.
Software Reengineering is the process of updating software without affecting its functionality. This process may be done by developing additional features on the software and adding functionalities that may or may not be required but considered to make the software experience better and more efficient. As far as the definition goes, this process also entails that the software product will have improved maintainability. Thus, software reengineering is a step towards continuous improvement of software for it to be handled better by developers and clients alike. Additionally, it is a way to make existing products continue in service.
Why is there a Need for Software Reengineering?
The need for software reengineering becomes an integral part of improving the quality of your products. This process adds more value to your business as it does not only better your services but also contribute added revenue.
Software reengineering is a cost-effective method for software development. Why? This process allows you to discover unnecessary steps and resources that have been implemented in your current software and remove them from the implementation, therefore minimizing the costs (time, financial, direct, indirect, etc.) that could be incurred. If a client needs a product you already have but requires added features, you may only have to re-engineer the existing one to save costs.
In relation to cost savings, this process also makes your products easier to maintain. Being able to re-inspect your software leads you to point out several missteps in the current implementation allowing you to decide on enhancing your procedures of the development. This, therefore, makes the maintenance duration of your software development life cycle much easier to execute and sustain.
How is Software Reengineering Done?
Software Reengineering basically undergoes three main processes. These are (1) reverse engineering, (2) restructuring, and (3) forward engineering.
A simple Google search would tell us that reverse engineering, by definition, is “the reproduction of another manufacturer’s product following detailed examination of its construction or composition”. However, in software, it is not only limited to applying this process to another manufacturer’s product but as well as products that have already been produced by your own company.
This is done by thoroughly analyzing and inspecting the system specifications and understanding the existing processes. Systematically, reversing the software development life cycle of software implementation best fits this procedure as it ordinally unravels each layer from higher level to lower level points of view of the system.
Once the reverse engineering is done and the appropriate specifications have been identified, the restructuring of the system is performed. Restructuring deals with the rearranging or reconstructing the source code and deciding whether to retain or change the programming language. However, this shouldn’t impact the existing functionalities of the software but further enhance them instead for more reliable performance and maintainability.
Another part of this procedure is the elimination or reconstruction of the parts of the source code that often cause errors in the software (may also be debugging). Aside from that, eliminating obsolete or older versions of certain parts of the system (such as programming implementation and hardware components) will also be performed to make it up to date.
The flow ends with forward engineering being the last set of steps. This is the process of integrating the latest specifications based off of the results of the evaluations from reverse engineering and restructuring. In relation to the entirety of the process, this is defined relative to reverse engineering, where there is an effort to build backward, from a coded set to a model, or to unravel the process of how software was integrated.
Additionally, it is also similar to software engineering but only with the assumption that the development life cycle has already undergone reverse engineering.
There is no specific Software Development Life Cycle (SDLC) model to follow in Software Reengineering. The SDLC model will always depend on what fits best with the development and implementation of your product. However, like software engineering, this is a systematic development that involves processes within processes and requires thorough inspection for seamless results.
Where can I find People to work on Software Reengineering Projects?
Many IT companies have now grasped the concept of software reengineering as they do software engineering. On the client’s side, many small to medium business owners resort to offshoring this part of their process to other countries with much lower costs and pay rates.
What is offshoring? Offshoring is the expansion of your company’s (or part of your company’s) operations to another country with the intention to save on costs, minimize training, gain more profit, and access the global IT industry market with lesser supervision but full control.

Find Software Engineers at Full Scale
Full Scale is a roster of talented individuals dedicated to producing quality outputs through our range of development services. We achieve this through our Guided Development program where our clients are in control of the projects while we take care of the rest.
With a pool of software development teams experienced in different programming languages, our company is more than ready to take on projects that will help you with the development of the software system you want for your business. As we are exposed to the field of software engineering and software development life cycle models, working on software reengineering projects would come in handy.
One advantage when engaging in an offshore business, such as Full Scale, is the retainership of our services with minimal costs for you. Software development and maintenance teams are expensive to put under a business’ vertical but in offshoring this part of your business, you can save a lot of costs.
Full Scale also offers other services that help business grow in the digital world such as web and mobile application development, search engine optimization, graphic design, business consultancy, and content writing.
