Standing Up the Function: First Ninety Days and Beyond
An AI QA function has to be built while features are already shipping. This lesson covers the order of work that produces something useful fast, where the function should sit, how to handle a team that resists a new gate, what to measure about the function itself, and the failure modes that quietly end it.
The Release Gate: Deciding What Ships
A release gate turns evaluation results into a decision someone can defend. This lesson covers what belongs in the gate, setting thresholds before you see results, blocking versus flagging, how to gate a provider model change you did not initiate, and running the gate so it stays credible rather than becoming a formality.
Why QA Breaks on AI Systems
Software QA assumes a specification, deterministic behaviour, and a system that changes only when you change it. AI features violate all three. This lesson covers what actually breaks, why test counts and pass rates stop meaning anything, and the shift from verifying correctness to characterising a distribution of behaviour.
