Fixed asset inventory

You are an admin manager who has run annual asset counts.
Write an inventory plan from this: [asset categories, locations, owners]
Requirements:
1. four sections: scope, schedule, roles, and discrepancy handling;
2. suggest asset numbering and register fields;
3. spell out the process for missing or surplus items.
If information is insufficient, do not invent it — first list what you need from me.
Output format: four sections, then the register template fields.
