1. The Rapid Application
Development Model
Looking for an agile and accelerated development process that can drive
product innovation? Look no further than the RAD model!
2. Overview of RAD Model
What is RAD?
RAD is a linear sequential
software development
process that emphasizes
on rapid prototyping and
quick feedback over pre-
planned design and
models.
Why is it used?
RAD is ideal for time-
sensitive development
projects in which
requirements are well
understood and the scope
of the project is narrow and
well defined.
How does it work?
The RAD model follows
four phases: requirements
planning, user design,
construction, and cutover.
3. Phases involved in RAD Model
1
Requirements Planning
Identify project requirements and
define the project scope.
2
User Design
Create a prototype to be reviewed
by users for feedback and design
revisions.
3
Construction
Iteratively develop the software by
adding functionality to the
prototype.
4
Cutover
Test and implement the software
into production mode.
4. Advantages of RAD Model
Increased Collaboration
The involvement of users,
developers, and testers at
every phase ensures better
understanding of the
application and increased
collaboration among team
members.
Time Saving
The iterative process
significantly reduces
development time and speeds
up the delivery of the
software.
Flexibility
The RAD model is flexible and
allows changes to be made
easily, enabling fast
adjustments to evolving
requirements.
High Customer
Satisfaction
The regular feedback and
evaluation ensure that the
final software meets customer
5. Disadvantages of RAD Model
1 Unclear Requirements
As RAD emphasizes less
on analysis and more on
the rapid creation of
prototypes, there is a risk
that requirements may lack
clarity or fail to address the
big picture.
2 Unrealistic Timeframes
The time-boxed approach
may result in unrealistic
project timeframes, leading
to an increased risk of
developing a product that is
not market-ready.
3 Costly Implementation
RAD requires significant resources, in terms of manpower and
budget, which may make it inaccessible for smaller organizations
or projects with limited resources.
6. Comparison with Other Development
Models
Waterfall Model
The Waterfall model is a linear sequential
development process that follows a pre-
determined and pre-planned staged approach.
V-Model
The V-model follows a sequential process for
software development with an emphasis on
testing at each stage.
7. Examples of RAD Model Implementation
Mobile App Development
RAD is a popular model to
develop mobile applications
that have a narrow and well-
defined scope with well-
understood requirements.
Web Development
RAD is used in situations in
which fast and iterative
development is required, such
as in the development of web
applications with basic
features.
Automation Testing
RAD is an excellent method for
automating test cases,
reducing manual testing efforts,
and expediting the
development process.
8. Conclusion and Recommendations
Conclusion
RAD is an excellent approach to software
development in certain scenarios that require
quick delivery and iterative processes.
Recommendations
When considering the RAD model, it's
important to evaluate the project scope,
resources, and urgency to determine if it is
the right fit for the situation.
