Delegate in this order
- Calendar (with clear rules)
- Inbox triage (with draft-only permission)
- Scheduling (with confirmation rights)
- Weekly reporting (drafted by them, reviewed by you)
- Vendor + contractor comms
- Bookkeeping data entry
- Sales follow-up
The one rule
Document decisions as they happen. Every 'I would have done it this way' becomes a line in the SOP.
