Structure your answer using this framework:

1. **Clarify the goal**: What is the business objective? Increase revenue, improve retention, expand to a new market?

2. **Identify the user**: Who is the target user? What is their current pain point or unmet need?

3. **Explore solutions**: Brainstorm 3-4 possible approaches. Don't commit to one immediately.

4. **Prioritize**: Use a framework like RICE (Reach, Impact, Confidence, Effort) to compare options objectively.

5. **Define metrics**: How will you measure success? Primary metric + 2-3 guardrail metrics.

**User Segmentation**: Different user segments have different needs. Power users want advanced features. New users need simple onboarding. Enterprise users need security and compliance.

**Competitive Landscape**: What do competitors offer? Where is the opportunity for differentiation?

**Trade-offs**: Every product decision involves trade-offs. Speed vs quality. Simplicity vs flexibility. Short-term engagement vs long-term retention. Make these trade-offs explicit and justify your choice.

**Success Metrics**: Use the AARRR funnel - Acquisition, Activation, Retention, Revenue, Referral. Focus on the stage most relevant to the current business goal.

**Experiment Design**: Validate with an A/B test before full rollout. Define the minimum detectable effect, required sample size, and duration. Set guardrail metrics.

**Iteration Plan**: Start with an MVP, measure results, and iterate based on data. Define go/no-go criteria for each phase of the rollout.
