In today's highly competitive business world, beating to the punch is crucial. But it cannot be done at the expense of effectiveness, excellence, and efficiency. This means that 21st Century businesses have to develop software with methodologies that can make the magic happen in the least amount of time and do so with accuracy and excellence.

Rapid Application Development (RAD) is a tried and tested methodology that provides swift development and quality results. It is a form of Agile Software Development Methodology that is sure to provide better results compared to other software development methodologies. This methodology is designed to make the most of the software development process. While the primary objective of this methodology is to accelerate the software development process, it does so without compromising on effectiveness and excellence.

This model should be used for a system with known requirements and is on a short deadline. It is highly advantageous for projects where requirements can be modularized and reusable components can be made available for development purposes. The model is also great for projects where pre-existing system components can be used in developing a new system with minimal changes. Domain experts are crucial for the success of this model. This is because the effectiveness of this model relies on relevant knowledge and expertise. This is a model that should be chosen when the budget permits the use of automated tools and techniques required.

RAD can be used effectively if the project can be broken down into small modules wherein each module can be assigned independently to separate teams. These modules can later be combined to form the final product. This makes it easy to achieve intended goals in the software development process as it allows a more efficient structure. active user participation in the development process.
