I was operating under the assumption of reasonable execution risk. If you can't even get the product out the door then you'll definitely fail. My main point was that it's hard to disprove ideas that are feasible and are something people want. To pursue such an idea is a gamble; to not pursue is also a gamble. I've unfortunately been wrong in both ways ;)
And how would you arrive at that assumption? Generally speaking a simple business plan is what states those risks and explains these essentials of your execution plan.
