What is Rapid Application Development?
Rapid Application Development model is a type of Agile software development and came into existence when it came to know that traditional waterfall model is not effective when the software is in testing phase. When the program is in testing phase, then changing the core functionalities is too hard.
Rapid Application development model mainly focuses on the rapid prototyping rather than complete require gathering at the same time. Speedy feedback over lengthy development and testing cycles can be taken in RAD model. Due to this, changes needed to take place at the time of final testing will reduce and so reduces the complexity to do changes at the extreme end of development phase.

| RAD methodology |
In other words RAD is less talk and more work, and yes more and more testing. RAD de-emphasizes the strict planning and emphasizes the development cycles. That means at the initial stage, roughly requirements are gathered and designs a rough software mode according to rough core functionalities at the initial stage. Then Customer goes through this model and according to his feedback and requirements next development starts. Requirements can added in any stage of development. And according to these changes designing and development takes place.
How does it work?

| RAD Development |
1. Requirement’s planning-
This development model includes requirement planning. Requirements can be added in further regardless of other models to plan it all in the beginning.
2. User Design-
It is a main part of RAD Model which keeps it apart from other models. When goal of project decided you are free to move towards development. Various prototype iterations builds project design. Practically it is a customizable software development in which developer designs a prototype, then user tests it and then they evaluate what worked and what didn’t. Basically, both the developers and clients work together to achieve the goal of a project.
3. Rapid Construction-
In the construction phase, the prototypes designed in previous phase are converted to working models. Majority of bugs are detected during iterative design phase, so it becomes easier and quicker to build a final working software model. However, client can give requirements, suggest changes and modifications that can solve when they came to know. The product is continuously working by designers, coders, programmers, testers until the final product meets client’s requirements and objectives.
4. Cutover
It includes all the final changes, data conversion, testing, and the changeover and the new system get ready. This phase includes user training. This phase includes performance testing of final product.
When you can use Rapid Application Development ?
1. When you need to complete a project quickly-
Rapid Application Development is your best choice among other development models when you have got a tight deadline to meet or you’re under pressure to deliver something that works properly. Decision for using RAD saves your time that you would otherwise need to go through a long requirement planning and design phase. With RAD, you can take an on-the-fly approach, which can change the direction of the development efforts, on a dime.
2. When You Can Reliably Test Your Prototypes?-
If you have a lot of users and they can give you accurate feedback, then RAD is your best choice. Prototypes built through the Rapid Application Development Model depends on the feedback from previous iterations, so accurate feedback from dependable sources is progressively helpful.
3.When You’ve Got the Budget-
The Rapid Application Development method is cheaper than other development models. However, there are some cases where RAD can be expensive. At that time you may need to hire technology experts and give them fitting salaries but on the brighter side, if you’ve got the staff then you can get your idea developed much quicker than any other model.
4. Minimum Changes and Less Time –
When already existing system components have to used in developing a new system with minimum changes, this model is the best choice.
In short if you have less time to develop a software then you can go through this RAD model. This model gives you the best software solution in minimum time with high effectiveness.
Why you should use RAD Model?
There is nothing more important for a developer than obtaining user feedback during the software development. RAD model provides a way to give continuous feedback by repetitive iterations and prototype release, which gives entire team significant assessment and analysis at the right time. Due to frequent iterations, components and prototypes being released , the progress of overall project and independent components can be easily measured. In RAD, each element of development is partitioned thoroughly and hence it can be easily altered when in need. Code can be changed easily because RAD software is flexible.
Advantages of RAD-
- You can change requirements at any time
- Customer feedback is at higher priority
- Quick Reviews
- Required less development time
- More productivity with fewer people
- Time between prototypes and iterations is short
