Treat error discovery as a required stage of AI product evaluation: first identify and categorize hidden failure modes, then prioritize fixes based on their impact on users.
AI products can appear effective while still failing in consequential edge cases. A repeatable discovery process helps teams direct scarce engineering effort toward failures that most undermine customer value and trust.
Review a representative sample of recent AI outputs and ask: What recurring failure categories appear, which users or workflows do they affect, and which single category should we fix first?
