Recommend a Requirements Prioritization Framework and Apply it

As a Project Lead, you have a backlog of 15 project requirements for a new SaaS product feature. Propose a suitable prioritization framework (e.g., MoSCoW, RICE, Kano Model) and explain why it's appropriate for a SaaS product. Then, briefly describe how you would apply it to prioritize these requirements.

**Role**: Project Lead / Project Manager
**Context**: Managing a large number of requirements and needing a structured approach to decide what to build first.
**Specifics**: Choose one framework, explain its core principles and benefits for a SaaS product. Then, describe a step-by-step process of applying it, including what type of information you would need to gather for each requirement (e.g., business value, effort, risk, customer satisfaction).
**Output**: An explanation of the chosen framework, its rationale, and a step-by-step application guide.
