Explanation:
The Prototype Phase is also called the “Proof of Concept” Phase. Whether it’s
called one or the other depends on what the creator is trying to “prove.” If the main deliverable of
the Phase includes a working version of the product’s technical features, it’s a “prototype.” If the
main deliverable just looks like it has the product’s technical features, then it’s a “proof of concept.”
Prototypes can save time and money because you can test some functionality earlier in the
process. You don’t have to make the whole final product to begin testing it.
