What is the Rapid Application Development (RAD) Model?
RAD model refers to Rapid Application Development and it is a type of Incremental Model. The components or functions are developed in parallel and it can handle small projects as well as medium projects. In this model, any changes can be made at any stage. It has high productivity due to less number of people.
Phases of RAD Model
RAD model consists of 4 basic phases:
- Requirement Gathering
- Rapid Prototyping
- Construction
- Deployment
Difference between RAD Model and Spiral Model
Rapid Application Development (RAD) model and Spiral Model both are software development life cycle model. The Spiral Model is best for large, complex projects with significant risks, requiring detailed planning and extensive documentation, while the RAD Model focuses on rapid development with easy changes, using smaller teams and minimal planning, suitable for small to medium projects. The Spiral Model prioritizes risk management and high assurance, whereas the RAD Model prioritizes speed and flexibility with lower costs.
