What's the opposite of "prototype product"?

Question

From an Information Technology perspective, what's the opposite of Proof of Concept (prototype)?

I'm looking for a better word which means "full-fledged version".

Opposite of "proof of concept"? "Disproof of concept"? While I've never heard this used, it is clearly needed for certain pieces of vaporware. — Peter Shor, Mar 8, 2013 at 15:24
Interesting that you used "full-fledged". It seems quite apt. i.word.com/idictionary/full-fledged It comes from "fledge" which literally means (for a bird) to become ready to fly on its own. i.word.com/idictionary/fledge — Brian Hitchcock, Jul 11, 2015 at 8:10

The opposite of a prototype — or a blueprint, or a sketch, or a mock-up, or a model — is a finished product or production version.

Any other terms? I think he's looking for a synonym of "production version", like how "prototype" is the synonym for "alpha version".

Just production. 'Is this production or just a prototype?' - The opposite of prototype is a wall hanger, as w/e it is, it's on its way out of use as opposed to coming into it.

I would call it a turnkey project. Wikipedia explains this as:

a type of project that is constructed so that it could be sold to any buyer as a completed product.

But with full-fledged version they would certainly know what you are referring to.

Like the word "TurnKey", But I doubt if people would really understand it. Glad to learn a new word today. Thanks.

@vonjd, "turnkey" is the wrong term. Full fledged products can be both turnkey and non-turnkeys, they are not related in any way.

"Turnkey" refers to how the product is delivered -- whether the supplier or the customer is responsible for installation and setup.

It can be called as Beta Version or Feature Complete.

(Reference: see the Wikipedia article.)

Beta still has the connotation of a product that is known to be not quite ready. Technically, you're right; a beta version should have everything the customer has asked for and behave as they said it should; the beta test period is where you discover anything that differs between "what they asked for" and "what they need/want". It is common knowledge, however, that those two rarely meet on the first try.
