The AI Feature RACI: Why Four Green Dashboards Add Up to a Broken Product
An AI feature regresses on a Tuesday. The eval CI is green. The guardrail dashboards are clean. The retrieval P95 is in line. The model provider had no incident. And yet the support queue is filling up with users who say the assistant "feels worse this week." The PM is the only person in the room who can name the regression, and even she cannot tell you which dashboard would have caught it. Welcome to the seam bug — the kind of failure where every individual artifact owner can prove their piece is fine, and the integrated experience is still broken.
This is the predictable result of how AI features get staffed. The owner-of-record list looks reasonable on paper: a prompt author owns the system prompt, an eval owner owns the offline test set and CI gates, a tool/retrieval owner owns the function calls and search index, a guardrail owner owns moderation and policy filters. Plus a model-selection decision that often lives outside all four — sometimes with a platform team, sometimes with whichever engineer most recently filed the procurement ticket. Five owners. Zero of them are on the hook for "does this feature work for the user."
