Introduction:
- The RAD Model, developed in the 1980s, focuses on rapid prototyping and iterative development.
-
Phases of the RAD Model:
- Business Modeling:
- Gather requirements through workshops and discussions.
- Data Modeling:
- Design data models based on gathered requirements.
- Process Modeling:
- Define the flow and logic of the software.
- Application Generation:
- Rapidly develop and prototype the software.
- Testing and Turnover:
- Perform component testing and user feedback loops.
- Cutover:
- Deploy the software and transition to production.
-
Advantages:
- Speed: Rapid prototyping and iteration lead to faster software development.
- Flexibility: Easily adaptable to changes in requirements.
- User Feedback: Early and continuous user involvement ensures the software meets user needs.
-
Disadvantages:
- Dependency on Skills: Requires skilled developers and analysts for rapid development.
- Documentation: Limited documentation can lead to knowledge gaps in maintenance.
- Scope Management: Scope creep may affect project timelines and budgets.
-
Real World Application of RAD Model in Designing JUST-Learning App:
- Example: Developing a new feature for collaborative project management on the JUST-Learning Portal, allowing students to work together on assignments and projects.
- Benefits: Enables rapid prototyping and iteration based on user feedback, ensuring the feature meets user expectations. Quick deployment facilitates early adoption and continuous improvement.
- Restrictions: Requires rigorous planning and skilled resources to manage rapid development cycles effectively. Limited documentation may pose challenges in long-term maintenance.
Conclusion: The RAD Model is suitable for projects requiring rapid development and frequent changes, such as enhancing collaborative features on the JUST-Learning Portal. It emphasizes speed, flexibility, and user involvement throughout the development process.
