It helps to at least write down requirements. And not requirements in that "it must use Reddis", but customer, user, performance, cost, etc requirements.
A one page requirements document is like pulling teeth apparently.
Oh yes, you want a vague idea of where you're going, and concrete plans for the next step. If you can't even get one-page requirements then something has gone very badly wrong.
