A simple analogy
A PoC is a sketch. A pilot is a limited print run. Production is the full press. Each stage costs more, moves slower, and delivers more confidence than the last.
What it looks like in practice
A logistics company spends three weeks on a route optimization PoC. It works. They run a 90-day pilot with one region. Validated. Full production build takes eight months and the serious engineering budget.
When to use it
Every AI investment should move through these stages deliberately. A PoC answers 'can this work.' A pilot answers 'does this work in our context.' Production is the decision to operate and support it indefinitely.
When to avoid it
Do not treat a successful PoC as proof the production system is built. The gap between a working demo and a maintained, scalable, secure product is where most AI projects underestimate both cost and time.
What it signals about cost
Production typically costs several times more than the PoC.
