The process of developing software is often tedious and time-consuming, conventional software development methodology often follows the research, design, coding, testing, implementation and maintenance stages.
However, with the expanding internet and the need to deliver quality software to businesses and organizations, developers would come up with Rapid Application Development (RAD), which is believed to be a faster approach.
Initially, RAD was known as Rapid Iterative Production Prototyping (RIPP), having been introduced by James Martin in 1991. Here, software was only developed coming up with software data models using structured techniques.
This step was followed by the refining of these data or business models in a way that they are practical and deliver the desired product. Subsequently, these two processes would be iterated to develop other functionalities of software.
To bring everything into proper perspective, the developers would later on come with a more structured way of developing software.
Requirements Planning Stage
In this stage, developers focus on the outcomes that are to be achieved by the project once it is complete. It is at this stage where potential problems that could arise are identified and nipped in the bud.
Generally, it follows the principle of delivering software faster than the conventional methods by employing the use of prototypes.
This stage makes the difference in the entire Rapid Application Development structure. It follows that the development entails the use of prototypes which can be reused in the development of subsequent models.
The whole essence of this stage is that while it is the most intensive of all the stages, it clears the doubts that may have been harbored by developers. What happens here is that the prototypes are designed first then they are given to users to test them and feedback delivered.
This stage, unlike in the previous methods of Software development is the easiest. It involves remodeling all the prototypes that may have been recommended by users in the design stage and redesigning them for the better.
Also, developers now have a clearer path on the type of software the users would find relatable and also offer a great user experience.
This stage entails preparation for construction, coding, integration and testing of the application.
Being the last stage in every software development process, all compatibility issues and the tests will have been carried out and the software is rolled out to its end users.
With prototyping and iteration, this process can actually be completed much faster than with traditional software development strategies which took longer.
Why Developers Prefer RAD
RAD happens to be the fastest route because of the use of prototypes which are then iterated throughout the whole phase of application development.
RAD also allows for integration at every stage of the prototyping as it ensures problems are easily identified and dealt with before the application reaches more final stages.
Addition, removal or modification of features is equally easier as the developers just have to access the specific module and effect the changes as desired.
Rapid Application Development has come a long way to revolutionize the app business with more efficiency, timeliness and flexibility of adding features easily regardless of the stage of construction.
This has meant more work can be done within shorter time-frames to get more businesses to the specific users who need them.
