PoC vs Pilot vs Production

A PoC (proof of concept) answers "is this technically possible?" in a throwaway setting — narrow scope, synthetic or limited data, no durability guarantees. A pilot answers "does it work for real users under real constraints?" — bounded blast radius, real workflows, and enough monitoring to learn. Production answers "can we own and operate this indefinitely?" — full controls, SLAs, on-call, and an auditable outcome document.

The bar rises at each step. A PoC can succeed on thin evidence because its reversal cost is near zero — you throw it away. Production demands proof precisely because backing out is expensive. Skipping the pilot is how a demo that impressed a room becomes an incident.

Each stage also carries different compliance posture and stakeholder sign-off needs. A pilot may run under a limited waiver; production usually cannot. Treating stage boundaries as real gates — each with its own evidence — is the discipline the exam rewards.
