Managing director Paul Benney started doodling in meetings as a way to visualize ideas and business strategies. He found diagrams to be a more effective way to outline plans compared to bullet point lists. Sunni Brown is leading a "doodle revolution" and argues that doodling and visual note-taking are effective learning and thinking tools. Visual note-takers like Mike Rohde capture details from meetings and conferences in sketches and make them available online. Researchers find that visual representations of ideas can be more memorable and engaging than text alone.
