Prompt: Propose Research Directions and Solution Approaches to Improve Business Performance

Context

Assume a large-scale, web/mobile, cloud-backed product with millions of users and multiple services. You are a software engineer in a system design and engineering technical screen, tasked with proposing pragmatic, measurable ways to improve business performance.

Task

Propose 3–5 research directions with concrete solution approaches to improve business performance. For each idea, provide:

1. Problem definition and why it matters
2. Target users or segments
3. Key success metrics (e.g., conversion, retention, revenue, cost) and guardrails
4. Required data and instrumentation
5. Experimental design to validate impact
6. Engineering or ML components (if any)
7. Risks and mitigations
8. Phased rollout plan

Keep the proposals technically grounded and measurable, with clear validation and rollout strategies.
