Keep your guides up to date

You're helping me plan how to keep my business guides up to date. This is a plan for me to check. Don't change any documents.

My guides (one per line: name, who looks after it, when it was last checked, how often it changes):
[PASTE YOUR LIST]

Who signs off changes: [E.G. ME]
Things that should trigger a check: [E.G. A PRICE CHANGE, A NEW TOOL, A COMPLAINT, SOMEONE LEAVING]

Please:
1. Suggest how often each guide should be checked, based on how often it changes. If I haven't given enough to go on, say "my decision".
2. Make a simple table: guide, owner, how often, next check.
3. Write the steps for changing a guide: who suggests a change, who checks it, who signs it off, and how the team hears about it.
4. List the events that should trigger a check straight away.
5. Flag any guide with no owner, or two owners.

Rules:
- Use only what I've told you. Don't invent owners, dates or rules.
- If two guides disagree, don't pick one. Flag it for me.
- If any of this is for my team, it's a draft for me to check first.
