Study Notes
- Rapid Application Development (RAD) involves successive development iterations, beginning with a feasibility study, followed by design, implementation, testing, and evaluation in each iteration, resulting in a prototype that is refined based on user feedback.
- The Spiral Model, similar to RAD, consists of project cycles with stages like determining objectives, identifying and resolving risks, development and testing, and planning for the next iteration, making it suitable for high-risk projects with complex risk analysis.
- Agile methodologies aim to enhance software development flexibility and adaptability to changing user requirements, with common methodologies like Scrum and Kanban, emphasizing user satisfaction over documentation and involving iterative development with prototypes at the end of each cycle.
- Extreme Programming (XP) is an example of a framework within agile methodologies, focusing on values like communication, simplicity, feedback, courage, and respect, with practices such as 40-hour work weeks, pair programming, coding standards, and refactoring to improve code quality without changing functionality.
- While RAD is suitable for low-budget projects with a focus on quick production, the Spiral Model is ideal for large projects with high risks, and agile methodologies like XP emphasize constant communication with end users, potentially leading to increased costs due to the need for user-programmer interaction.
