Why teams get this wrong
A surprising number of AI projects do not fail because the model is weak. They fail because the task was never properly bounded in the first place. Or because memory was added as a feature instead of justified as a behavior improvement. Or because tool use looked impressive in a demo and then broke quietly in production. Or because the evaluation framework produced clean numbers that had very little to do with whether the system was trustworthy once people depended on it.
Teams end up optimizing average-case capability while the real cost comes from worst-case behavior: quiet failures, uncontrolled widening, and confidence without grounding. The gap between prototype and production keeps widening because the system layer is treated as an afterthought.
