Brief strength

Planned

How much brief does a maker need beside a concept picture, and what does each level cost from concept to model?

Result

Shown once every version is rated.

Setup

Variable: Input: concept only; concept and a mini-brief; concept and a strong brief; a strong brief without the picture; the name and a triangle budget only (run 12)
Held: Assets (five Munch wonders), the picked concept, the request's hard lines (box, origin at the ground centre, cap), makers, rounds, camera
Ceiling: Not set

Hypothesis

A mini-brief beside the concept gives most of the gain of a strong brief at a fraction of its cost; a strong brief without the picture fits the box best but drifts from the look; the concept alone varies most between makers.
