Rapid Application Development (RAD)
What is rapid application development?
-
Rapid Application Development (RAD) is a software development methodology that emphasises fast and iterative development
Steps in the model
-
Requirement planning: Gather general system requirements, define constraints and assumptions
-
User design and prototyping: Collaborate with users to develop prototypes, ensuring alignment with user needs
-
Construction or iterative development: Build the system incrementally, with continuous user feedback and adaptation
-
Cutover or deployment: Transition the product into the live environment, including user training, support, and documentation
-
Maintenance and updates: Continue to adapt and improve the system based on user feedback and needs
Rapid Application Development (RAD) Model of Software Development
Benefits
-
Speed: Enables rapid development and delivery of a high-quality system at a relatively low investment cost
-
User involvement: Clients are involved throughout the development process, ensuring that the system aligns with user needs and expectations
-
Flexibility: Allows for changes and adaptations to be made quickly as requirements evolve
-
Incremental development: Promotes development in small increments, with constant feedback and adaptation
Drawbacks
-
Dependent on strong team collaboration: Requires skilled and collaborative team members, which can be a challenge to assemble
-
Potential lack of quality: The focus on speed might lead to skipping rigorous testing or documentation, impacting the quality
-
Not suitable for small projects: The intense collaboration and iterative approach might be overkill for simple or small-scale projects
-
Can lead to scope creep: The flexible nature may lead to uncontrolled changes in requirements
Suitability
-
Rapid Application Development is most suitable for projects where rapid delivery is required and where requirements can be developed and refined on the go
