That a prototype of the solution tested well with a group of users
That real users exist who want the product the team is proposingCorrect answer
That enough user interviews have been run to call the phase finished
That the idea is a good one, in the considered judgement of the team

Show answer & explanation

Correct answer: B. That real users exist who want the product the team is proposing

Explanation

The principle — discovery is defined by what a team ends up knowing, not by what it did.

Why the key is correct — Cagan's first finding is about demand: First, you need to discover whether there are real users out there that want this product. It is a claim about people outside the building, and nothing about the shape of the solution establishes it.

Why the others are wrong — a prototype that tests smoothly speaks to the second finding, which concerns the solution being usable, useful, and feasible. A team's collective judgement is one verdict where Cagan asks for two, and running a round of interviews is an activity rather than a finding.

Remember this — the first question is whether anybody wants it; everything about the solution comes second.
