Which of the following models is included in the Software Development Life Cycle (SDLC)?

1. Agile

2. CRISP-DM

3. RAD

4. All of the above

The correct answer is: Agile

The correct answer encompasses various methodologies, and Agile is indeed one of the prominent models within the Software Development Life Cycle (SDLC). Agile focuses on iterative development, where requirements and solutions evolve through collaboration among self-organizing cross-functional teams. The Agile model is characterized by its ability to adapt to changing requirements over time and encourages frequent inspection and adaptation, promoting a flexible and collaborative environment. This is a key aspect of the SDLC, as it ensures that software is developed incrementally and can quickly respond to user feedback and changes in the project scope. While CRISP-DM (Cross-Industry Standard Process for Data Mining) and RAD (Rapid Application Development) also represent models or methodologies that can be utilized in various contexts, they are not strictly classified under the SDLC framework like Agile. CRISP-DM is primarily focused on data mining and analytics processes, while RAD emphasizes rapid prototyping and iterative development, closely related to Agile but not typically categorized as part of the SDLC itself. Therefore, while Agile fits squarely within the context of the Software Development Life Cycle, the broader answer indicating all methodologies that might be considered models in software development would also include RAD as an appropriate model under certain contexts.
