When is Rapid Application Development (RAD) most suitable, and what is a key advantage?
Answers and Descriptions
Answer: The Spiral model incorporates risk analysis in each iteration, allowing early identification and mitigation (e.g., prototyping risky features). The Waterfall model addresses risks only in the feasibility stage, risking late discovery.
Description: This question deepens understanding of risk management, critical for project success. The comparison highlights the Spiral model’s proactive approach.Answer: Agile involves users through iterative sprints with regular feedback, ensuring adaptability. Prototyping involves users via early models but may focus less on iterative refinement. Agile is faster for evolving requirements, while prototyping suits initial concept validation.
Description: This question encourages critical comparison of development approaches. The referenced image (comparison chart) visually contrasts user involvement and speed.Answer: Object-Oriented methodology uses objects and classes for modularity and reusability (e.g., in Java development), improving maintainability. Structured methodology focuses on processes and data flow, less flexible for complex systems.
Description: This question highlights methodological advancements, crucial for modern system design.Answer: Waterfall limitations: Inflexibility to changing requirements and late testing. Agile addresses these with iterative development and continuous testing, allowing adaptability and early issue detection.
Description: This question reinforces understanding of model trade-offs, aiding in model selection.Answer: RAD is suitable for projects with tight deadlines and clear requirements (e.g., small business apps). A key advantage is rapid delivery through prototyping and user feedback.
Description: This question explores RAD’s niche applicability, enhancing knowledge of development strategies.
