What is an alpha prototype and when is it useful?
• Proof-of-concept prototypes are very different from alpha and beta prototypes and pre-production, which are all iterations of the commercial product development process.
• An alpha prototype is the first iteration of the commercial product. It is designed to meet the specification and acceptance test plan; however, as it’s the first iteration, it is likely to need modifications. An alpha prototype is useful for design feedback, user trials, market validation, etc.
