A prototype makes selected assumptions concrete enough to inspect. It may focus on one interaction or workflow rather than implement all the features and controls of a production system.
Feedback from a prototype informs revision, but a convincing demonstration does not prove readiness. Reliability, security and real user needs still require appropriate evidence before wider use.
ELI5
A prototype is a first version built to learn from, much like a rough model before a final construction.
For example, a team can try a simple assistant interface with a small group and use their feedback to change how it explains its progress.
Must a prototype include every planned feature?
No. It should include enough to investigate the question it was built to test.
Does a successful demonstration establish production readiness?
No. A demonstration can leave important reliability, security and operational questions unanswered.
