In the world of software development, you would always want to get your hands on an operational application as fast as possible in a cost-effective manner. This is where Rapid Application Development (RAD) gains significance. RAD has become an essential form of developing commercial software solutions.
Broadly following the principles laid down for Agile development, RAD is a software development technique that is designed to produce prototypes quickly and get working software as fast as possible. Unlike the conventional waterfall model, which result of each phase cascades into the development of the next phase, RAD gives a new way of developing software at a faster rate. Let’s look at the advantages of rapid application development that can help a business out:
1. Quick feedback from users:
RAD incorporates a user feedback method where the user’s opinion is taken into consideration at every crucial stage of the development process. Feedback is crucial for any developmental project. RAD enables software developers to receive feedback constantly throughout the journey of software development.
2. A progress that can be measured:
RAD process makes use of various iterations and prototypes of the software being developed. This enables you to measure the process made on the project realistically. This form of measurement allows people to plan, schedule and budget their projects accurately.
3. Highly adaptable:
RAD is designed to be as flexible as possible to incorporate new changes and suggestions concerning the user inputs. In this software development process, integrating any amount of changes in requirement and design is easily adapted. Therefore, Rapid application development is known for its highly adaptable nature.
4. Early system integration:
The process of RAD software development enables a user to integrate a prototype into the system during the early stages of the development cycle. In a traditional waterfall model, the support for system integration is towards the end of the development cycle. Whereas, in RAD, you can opt for early system integration where you can identify and fix critical errors early on.
RAD works on independent and functional components which are later integrated to form the entire system. These components make for easy modification and are highly helpful in the iterative process. The practice is similar to object-oriented programming. Here, those independent components are tested individually; therefore, the testing phase requires less time to process. These components can also be reused in other projects.
6. Fewer errors:
Since RAD has the capability to reuse its tried-and-test components over time, there can be fewer errors in the code. This way, the testing times are cut short, and the final product can reach the end-stage quickly. Also, since individual components are already tried and tested, there will be fewer errors in the final product and will have fewer defects than other models.
The rapid action development model is all about its pace, accuracy and flexibility it allows over traditional software development methods. It understands the key requirements, divides it into different components, and paves the way to quickly arrive at a completely functioning product.
