This document discusses various communication and advertising codes from the ASA, including requirements for ads to be honest, not misleading, avoid harming or offending audiences, and not pressure children or make unproven health claims. It then summarizes the strengths and weaknesses of different brainstorming and planning methods for developing an advertisement, such as mind maps, mood boards, style sheets, layout plans, brainstorming, pitches, reactions, sketches, and formal proposals. In general, visual methods helped illustrate ideas but took more time, while freeform brainstorming was easier but less organized.
