The work begins with constraint mapping: where the current product is brittle, what data is already available, and which user moments can benefit from machine assistance without changing the whole system.
Feature integration becomes much easier when retrieval, prompts, and failure states are treated like ordinary product infrastructure. That means tests, analytics, and explicit fallbacks.
If a user cannot understand what happened when the model is wrong, the feature is not production-ready no matter how impressive the demo looked.
