Standards and QA gates
I wrote the standards down first: what a program is, what every email has to contain, and what counts as launch-ready. QA checklists gate everything before it ships, whether a person or a machine made it.
Two of us run 10+ concurrent lifecycle programs because the standards, prompt libraries, QA checklists, and governance are written down. Custom GPTs do the work that can be trained.
We had ten-plus lifecycle programs and two people. Anything that lived in someone's head became a bottleneck. AI could take a lot of the repeatable work, but not without guardrails, because it'll produce confident garbage at scale if you let it.

We keep prompt libraries for the recurring work, versioned like anything else we ship. Governance spells out what AI is allowed to touch, what needs human review, and who owns the output. Custom GPTs in ChatGPT Enterprise are trained on those standards, and the trainable work runs through them now.
Contractor work is split into two buckets, trainable execution and real expertise, and we only pay outside rates for the second. I also set up value reporting for the martech stack, so every tool has to show what it contributed.

Campaign work modeled at 149 to 206 specialist hours has been delivered in roughly 71 to 74 hours by one AI-assisted operator: about a 60% reduction, projected to reach about 79% once the lifecycle agents launch. The modeling is against specialist-hour benchmarks, and everything still passes the same QA gate before it ships.
