About this routine

Sir John Hegarty, co-founder of BBH, built his career on absolute clarity in advertising strategy. He famously argued that if a briefing document exceeds one page, the strategy remains unclear. A disciplined creative brief development framework forces strategists to eliminate secondary clutter and focus on one compelling idea.

This 60 minute sequence guides you through defining the core problem, finding a single human insight, and condensing your strategy onto a single piece of paper.

By enforcing a strict one page limit, you force decision making before passing work to creative teams. The result is sharper creative execution and fewer rounds of revision.

Why this routine works

Forces clear strategic choices before creative work begins
Prevents document bloat and contradictory directions
Provides creative teams with a single unambiguous focus
