Which statement accurately describes a SDLC model?

1. The waterfall model emphasizes flexible development.

2. The iterative model emphasizes that the product may need to pass through the same phase multiple times, in a cyclical fashion.

3. The spiral model emphasizes a linear approach to project development.

4. The cascading model emphasizes simultaneous development of all project components.

The correct answer is: The iterative model emphasizes that the product may need to pass through the same phase multiple times, in a cyclical fashion.

The statement highlighting the iterative model accurately reflects a key characteristic of this approach within System Development Life Cycle (SDLC) practices. The iterative model is built on the premise that products can and often should go through cycles of development, whereby phases such as planning, analysis, design, implementation, and testing are revisited multiple times. This cyclical nature allows developers to refine and enhance the product based on user feedback and ongoing testing, thereby gradually improving quality and ensuring that the final product aligns closely with user requirements and expectations. This adaptability is fundamental to the iterative approach, as it recognizes that initial designs may not meet performance or satisfaction criteria, prompting teams to revisit earlier stages. The process promotes constant reassessment and flexibility, enabling teams to address issues as they arise, which is particularly valuable in dynamic environments like healthcare technology. In contrast, other models like the waterfall model and spiral model emphasize different processes. The waterfall model is known for a more structured and linear approach, where each phase must be completed before moving on, making it less flexible than the iterative model. The spiral model incorporates analysis and risk assessment at each stage but still follows a structured development path rather than a purely cyclical one. Also, there is no specific established "cascading model" in
