Decision boundary
The assistant prepares the record or queue. The authorized owner makes the live decision.
PPC support can collect evidence, check written rules, and prepare campaign notes. Social media support can organize approved posts and route public interactions. The owner decides what to spend, who to target, what a claim or offer says, what a post or reply says, and what goes live.
Put this in the first role brief.
"Use the approved source and written checklist to prepare the named PPC QA packet or social-media record. For PPC, hold and route budget, bids, targeting, audiences, tracking, conversion setup, campaign launches or pauses, final ad copy, offer claims, and live account changes. For social media, hold and route strategy, final captions, brand voice, offers, pricing, claims, sensitive replies, complaints, refunds, public disputes, publishing, account recovery, billing, ad spend, and platform permissions. Link the source, record the question, and name the authorized owner who decides."
