A Comprehensive Guide on Rapid Application Development

Explore More About Rapid Application Development (RAD)

We are living in an era where technology is changing on a rapid scale. Innovations in technologies rival their predecessors with more advancement and efficiency. So, to stay in the competition, every tech company, it doesn’t matter how big or small, needs to keep updating their tech and services.

The failure in not stay up-to-date has resulted in the ruins of many companies and startups.

What is Rapid Application Development? Why do developers prefer it?

Many developers adopt this approach where they are more efficient and quick in updating software and apps without wasting time. Developers develop it by creating multiple iterations with faster feedback responses. They can change the designs and functionalities of the app by testing it in a loop until and unless they don’t meet the result.

That is why developers prefer this approach of ‘Rapid App Development.’

Meanwhile, this kind of freedom is nowhere in the models like ‘waterfall.’ In this process, the whole development phase is singular.

It means that you can’t revert to changing a function if you have to move ahead in development. Such an approach is known as the waterfall model. Therefore if developers are moving forward with this model, they get stuck when clients want to change any function or process.

So it is not as flexible as rapid app development, where a developer can bring change in any function at any time, even after the app launch.

How does RAD help developers in app development?

Rapid application development (RAD), as its name suggests, it is the process of rapid testing and prototyping while developing an app. This process saves time for developers by making multiple copies of the app and updating it or changing its functionality accordingly. But not only this, in these types of app development, developers don’t have to start by going back to the drawing board. 

  • It helps developers focus more on the quality, which aligns toward a user-friendly experience.

Thus, by meeting all requirements of the clients, this method is widely being used by developers throughout the globe.

  • It is safe to say that rapid application development is now becoming a necessity for every kind of enterprise.

Thus, to meet the user’s needs at a faster pace in the global market. ‘RAD’ has come a long way in the IT industry to develop apps and software on a rapid scale.

What are the steps involving RAD?

In rapid application development, there are four basic steps:-

  • Project requirements
  • Prototypes 
  • Rapid development and feedback
  • Implementing the final product

1. Project requirements

  • It is the first step, and it is also a very important step in defining the success of the project. In this step, everyone related to the project comes together and discusses the requirements they need in their application.
  • During this meeting, they thoroughly work on planning to eliminate all the possible issues. Then the client’s vision is handed over to the developer team after the approval of all related members and stakeholders. 
  • Product developers come up with a general idea for the product. The client tells them their vision of the product and then works with the developers to reach an agreement on the requirements.
  • In this step, communication between everyone is essential in avoiding mishaps and mistakes, either in budgeting or deadlines.

2. Prototypes

  • After finalizing things on paper, the project moves into the hands of developers and designers with client supervision. 
  • Here developers develop a working model that is presentable to the client. And these steps of development keep repeating until and unless the application doesn’t meet the client’s approval. 
  • Here designers and developers create prototypes for the users to keep encouraging their active involvement in the project with their feedback. And it is better than showing the result to the test audience, where failing means going back to step one.
  • The process of getting feedback helps eliminate the errors and bugs in the early stages of development. When the prototype of developers meets the demands of the client, then that prototype becomes the roadmap of the final product.

3. Rapid Development & feedback

  • In this step, the prototype gets converted into a proper application.Then developers start their work of coding applications and system testing. Developers repeat this step as required to update the new features and components to be used in the app. 
  • This step takes less time as most of the errors and bugs have already been removed in the previous step.

Therefore, developers develop the final working model of the app in a short time compared to the traditional methods.

4. Implementing the Final Model

  • Here developers move the final product to the live environment to test the app for bugs and errors. In this step, full-scale testing of the app is done.
  • A developer may also spend this phase of product development making their implementation more efficient and maintainable, integrating their data with the back-end of production, writing thorough documentation for the product, and doing any other necessary maintenance tasks before handing it over.
  • Once the final product gets ready, developers do proper documentation related to the app and its cost, technicalities, features, etc

Advantages of RAD in the IT industry

While reading this article, you have already been familiar with the RAD. So, let’s summarize its advantages over other models:-

  • Time efficient
  • Adaptability
  • Fewer bugs and errors
  • Update requirements at any time
  • Constant users’ feedback
  • More productivity and cost-efficient
  • Any company can use the RAD model
  • Quality improvement
  • Risk reduction

Should you use the rapid application development model?

RAD model is very efficient, yet there are some criteria which you should examine, for example:-

  • If you don’t have users who can’t give you their honest reviews on your prototypes, then your final product will fall flat.
  • Check whether your team of developers is skilled and has good communication in-between.
  • Check whether or not you have the proper tools and software to execute the RAD model for your app.
  • Check if your client is open to suggestions and ideas.
  • See if you have an adequate amount of budget or not.
  • Check the level of technical risks related to your app.
