Which Software Life Cycle Model is iterative and allows for the cyclical repetition of the development phases, emphasizing risk analysis and management?

The Software Life Cycle Model that is iterative and allows for the cyclical repetition of the development phases, emphasizing risk analysis and management, is the Spiral Model.

Here are the steps to understand why:

1. The Spiral Model is a type of Software Development Life Cycle model that is a combination of iterative and sequential (waterfall) models.

2. It is designed in such a way that it can handle large and complex projects.

3. The Spiral Model emphasizes risk analysis and management. This means that at each phase of the development cycle, potential risks are identified and mitigated.

4. The model allows for the cyclical repetition of the development phases. This means that the development process starts with a small set of requirements and goes through each development phase for those set of requirements.

5. Once the first cycle (spiral) is completed, the next set of requirements are gathered and the cycle repeats.

6. This iterative process continues until the complete system is ready.

So, the Spiral Model is the Software Life Cycle Model that is iterative and allows for the cyclical repetition of the development phases, emphasizing risk analysis and management.
