The document discusses various communication methods for evaluating advertising projects:
1. Mind maps, mood boards, style sheets, and layout plans were used to generate initial ideas. These methods allowed adding many ideas easily but may lack depth.
2. Brainstorming, group idea generation, and informal pitches provided additional ideas and feedback to refine concepts. Working with others improved ideas but some lost interest using others' concepts.
3. Formal proposals and sketches required thoroughly thinking through the project, but took more time and some found them difficult to complete. Overall, the low-effort initial methods were preferred for idea generation while feedback from others helped strengthen concepts.
