Which model emphasizes risk management and incorporates user feedback throughout the development cycle?

The Spiral Model is designed to emphasize risk management by integrating iterative development with a focus on assessing and addressing potential risks at every stage of the process. This model is structured as a series of repeating cycles, or "spirals,” where each iteration allows for the incorporation of user feedback and necessary adjustments before progressing further in the project.

The key feature of the Spiral Model is the iterative risk analysis and user involvement. At each phase, developers assess risks which might affect the project, consult with users to gather insights, and make informed decisions based on that feedback. This process not only enhances user satisfaction but also strengthens the software's resilience by identifying and mitigating risks before they become significant issues.

In contrast, models like the Waterfall Model typically follow a linear progression without steps for revisiting earlier stages, making it less adaptive to changing requirements or user input during the development cycle. Similarly, while the Agile Model does prioritize user feedback, its primary focus is on collaborative development and flexibility, rather than explicitly emphasizing risk management as a central component of its structure. The Incremental Model also allows for user feedback and iterative development, but it does not specifically prioritize risk assessment and management in the same comprehensive way that the Spiral Model does.
