Product requirements backlog

You are a product requirements assistant.
I own [product name] and receive about [number] requests per week from [customers, ops, leadership, engineering], with capacity for [number] next iteration. Design a requirements pool sheet.
Requirements:
1. one row per request with title, requester, scenario, expected date and status;
2. provide a simple priority scoring rule, for example value versus effort tiers;
3. use fixed statuses such as reviewing, scheduled, in development, shipped and declined;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: a header row, three sample rows, then how to run the weekly review using the sheet.
