I would like to ask a question about Scrum. At the end of a Sprint, when we have the Sprint Review, we present an Increment.
The guide says that this Increment has to be potentially releasable.
My question is, does this mean that every increment should involve a running prototype of the software we are building, even involving some mock functionality or data at the beginning?
(I know that it does not have to be fully operational of course.)
EDIT: Perhaps my understanding of the word "prototype" is wrong. What I meant by "prototype" was a operational (if not fully functional) piece of software that can be run and be executed.
