What Is Rapid Application
Development?
Rapid Applicationa Development is development
model prioritizes rapid prototyping and quick
feedback over long drawn out development and
testing cycles. With rapid application
development, developers can make multiple
iterations and updates to a software rapidly
without needing to start a development schedule
from scratch each time.
RAD is a development model that came into
existence once developers realized the
traditional waterfall model of development wasn’t
very effective.
A major flaw in the waterfall model is that once
the program is in the testing phase, it becomes
difficult to change the core functions and
features of the software. This essentially leaves
you with software that may or may not fit your
evolving requirement.

Steps in Rapid Application
Development
Although RAD has changed over the years, these
four basic steps provide some continuity over the
years.
1. Define the requirements
2. Prototype
3. Receive Feedback
4. Finalize Software
1. Define the Requirements
At the very beginning, rapid application
development sets itself apart from traditional
software development models. It doesn’t require
you to sit with end users and get a detailed list
of specifications; instead, it asks for a broad
requirement. The broad nature of the
requirements helps you give specific
requirements at different points of the
development cycle.
2. Prototype
This is where the actual development takes
place. Instead of following a strict set of
requirements, developers create prototypes with
different features and functions as fast as they
can. These prototypes are then shown to the
clients who decide what they like and what they
don’t.
More often than not, theseonly prototypes are quickly
made to work, just to show off certain features,
without proper polish. This is normal, and the
final product is created during the
finalization stage where the client and developer
can both agree on the final product.
3. Receive feedback
In this stage, feedback on what’s good, what’snot, what works, and what doesn’t is shared.
Feedback isn’t limited to just pure functionality,
but also visuals and interfaces.
With this feedback in mind, prototyping
continues. These two steps are repeated until a
final product can be realized that fits both the
developers’ and client’s requirements.
4. Finalize Software
Here, features, functions, aesthetics, and
interface of the software are finalized with the
client. Stability, usability, and maintainability are
of paramount importance before delivering to the
client.
