Rapid Application Development (RAD) is an incremental software development process used to build systems within 60-90 days. It involves business, data, and process modeling, application generation, and testing. RAD is based on agile methods like Scrum and extreme programming and enables quick reviews, constant integration, and flexibility. However, it requires a modularized approach and skilled developers, and is not suitable for small projects or all applications due to higher costs.

3. Model Phases
• Business modeling
• Data modeling
• Process modeling
• Application generation
• Testing and turnover

4. Development model based on RAD
• Agile software development
• Joint Application Development (JAD)
• Scrum
• Extreme Programming (XP)

5. RAD Strengths:
• Quick initial reviews are possible
• Constant integration isolate problems and
encourage customer feedback
•Reduced cycle time, improved productivity and
lower cost
•Flexible and adaptable to changes
•Reduction in project risk, Can handle large
projects without a doubt

6. Disadvantage
• Requires a systematic approach for
modularized
• Requires highly skilled and well-trained
developers
• Cant use for small projects
• Requires more resources and money to
implement RAD
• All applications are not competible with RAD
