What is Rapid Application Development? A Detailed Guide

Imagine two companies aiming to create a new product.

Company A meticulously plans every detail before starting. They identify potential challenges, develop a comprehensive strategy, and only then begin building. While this approach ensures a solid foundation, it can be time-consuming, often taking weeks or even months.

Company B adopts a different strategy. They create a basic version of the product and release it quickly. By gathering user feedback, they continuously improve and add features. This iterative process allows for rapid adaptation to market changes.

Which approach is better?

While both have their merits, Company B’s method aligns with a development concept called Rapid Application Development (RAD). This approach prioritizes speed and flexibility.

In the following sections, we'll delve deeper into RAD, exploring its benefits and how it can revolutionize product development.

What is Rapid Application Development?

Rapid Application Development (RAD) is a linear sequential application development process that involves iterative development, which emphasizes incremental and repetitive development.

In other words, it centers around the active involvement of customers in requirements gathering, utilizing iterative testing of prototypes, reusing existing components, implementing continuous integration, and achieving swift product delivery.

IBM initially introduced it in 1980 as an approach to speed up application development. It works by dividing the process into smaller manageable iterations, also known as increments.

Furthermore, each iteration focuses on adding new functionality and enhancements to contribute to the overall software product.

Example:

To understand this concept, let’s consider the development of a mobile banking app using RAD.

Firstly, the team starts by identifying the core features and functionalities required in the app’s initial version. They break down the development process into smaller increments or iterations.

In the first iteration, the team focuses on implementing the basic account login functionality. Upon testing and completion of increment, it becomes a foundation for subsequent iterations.

In the second iteration, the team adds features like balance inquiry, transaction history, and fund transfers.

With each iteration, these new functionalities are built upon the existing login system, ensuring that the app becomes more comprehensive and valuable.

Subsequent iterations continue to improve the app by implementing features like bill payments, account settings, and personalization options. Consequently, the team follows a structured and sequential approach, with each iteration building upon the progress made in the previous one. Therefore, this incremental development process allows for quick feedback and adjustments, leading to a shorter overall development period.

The key benefit of this development model is that you can reiterate the process, continuously make changes, and add new functionalities without starting from scratch.

Phases of Rapid Application Development

Rapid Application Development (RAD) typically involves the following phases:

1. Requirements analysis

What distinguishes this approach from other development methodologies is its emphasis on gathering requirements individually rather than attempting to detect overall features collectively.

The process involves addressing and refining specific requirements in different stages or iterations of the development cycle rather than gathering all detailed specifications at the initial stage.

This can be understood by the example mentioned earlier:

Instead of incorporating all the features, the developers only include the login feature at first, then later, can linearly add more transaction-related functionalities. Rapid prototypes created in RAD serve as excellent targets for rapid application testing, helping identify usability and functionality issues before they become costly to fix.

2. Interface (UI) or user experience (UX) design

This phase contains the creation of prototypes; instead of collecting requirements, this stage focuses on enhancing the user experience by creating prototypes. Subsequently, these prototypes are showcased to clients to evaluate if they meet the desired standards. This phase involves developing the user experience and refining essential features.

3. Iterative development or construction stage

This stage, a crucial or near-final stage before deployment, involves collaboration among the production team, engineers, and programmers to identify and resolve bugs, issues, and other critical elements. Furthermore, it holds significant importance and may require a considerable amount of time. Notably, client feedback is precious during this stage. Consequently, continuous modifications and alterations are extensively incorporated into the work.

4. Deployment

The last stage of application deployment encompasses several crucial tasks such as scale testing, technical documentation, issue tracking, making final modifications, extensive testing, debugging, and conducting thorough robot testing before launching the application into live environments. This phase involves ensuring the application’s readiness for deployment, including all necessary testing and preparations.

Rapid Application Development (RAD) Vs. Traditional Software Development

Advantages and Disadvantages with Rapid Application Development

Rapid application development (RAD) is a popular method for application development; however, it’s important to note that it’s not a one-size-fits-all solution. While RAD offers numerous benefits, there are also certain downsides to consider when adhering to this methodology. Let’s explore both the upsides and downsides of this approach.

Upsides of RAD

Faster development and rapid delivery of a viable product.
Relevant and constant user feedback during the development.
Constant input from the clients or stakeholders mitigates significant failures and solves issues in real time.
Encourages regular, less formal communication.
Ability to scale and modify applications with changing requirements and user requests.
Less manual coding and reusable code.

Downsides of RAD

The development ecosystem must be modular, allowing components to be broken down.
Requires highly skilled developers.
Not ideal for projects with a high level of technical risk.
Require support and active participation from all members of the project team.
Tracking multiple iterations, maintaining constant communication, and managing feeds could present challenges.
Minimal up-front planning makes progress tracking less measurable.
