Short scoping call: we agree what the AI agent owns, which data and tools it uses, and how success is measured. 2. A working prototype early, then weekly demos you can test. 3. A production release with logging, guardrails, cost controls and handover notes your team can run. Clear communication, overlap with US and UK hours, and honest timelines.
