Who is the customer and what is the need that you are trying to solve for them? What is our strength—i.e., What do we do better than most; our unfair advantage? And if we don’t have one, why do we have a shot at winning? What did we learn from the experiments we ran? What is the business model—i.e., How will we get paid? Would you bet your career on this idea/solution/business? Why now? Where have you failed? What will you do differently because of it? What can I do to help? (This question forces humility as opposed to assuming you already have the answer.)
