We get it.
You don't have much time...and even fewer resources...and you don't get any "do-overs."
But it's really tough to get it right the first time.
That's why at Phase II, we "throw the first one away." And as quickly as possible.
That's the essence of Phase II's Presumptive Design approach:
Shovel the "wrong" stuff out of the way to discover the right outcomes as quickly (and inexpensively) as possible.
