Preface:
In 2024, the most anxious question for enterprise CEOs was: "Why don't we have AI yet?"
By 2025, their biggest headache became: "We invested so much in AI POCs (Proof of Concepts), why hasn't a single one gone live?"

This is a common phenomenon, termed by the industry as the "POC Valley of Death". Between Demo and Production lie countless chasms like data quality, concurrency stability, hallucination control, and cost accounting. Based on real-world cases from 100+ mid-to-large enterprises, this article provides a survival guide to cross this valley.
