A build takes three weeks and ends with a system you own. It only works when the problem is real, the people are reachable, and you can be in the room. Fifteen questions, each on a tested idea from the main books on validation, tell you which of those you have. And what to do first if one is missing.
Ready, nearly, or not yet, for the problem, the customer, demand, the solution risk and you.
One sentence in the shape every build starts from: who, the job, the cause, the cost, the workaround.
I run your answers through the method I use on my own ideas and send back one page: the problem in one sentence, why it happens, who the first ten customers are, the one assumption that would kill it, the smallest test, and one thing to do this week.
Answer for how things are today, not how you hope they will be. The line under each question says which idea it tests and whose. Nothing you answer leaves this page unless you choose to send the card at the end.
Answer all 15 and the verdict appears here, area by area, with the things to do first.

Send it with your answers and I return the full card within 3 working days, free, build or no build. It is the same method I use on my own ideas, and it comes back as one page:
