Dan has written a great book and recently uploaded this great set of visuals describing the dilemmas in the American health care debate. Look, learn and apply to your own way of communicating. The visuals are great!
Sometimes we forget that we have one: A Visual Language. You can use a visual langauge to convey messages, create meaning together with others and build shared understandings. When working in a team over a longer period of time, your team can benefit from building a shared visual language. Start with listing the most common words you use. Then draw some fast sketches of icons of each word. Then expand your vocabulary and link them in groups. Continue making rough sketches. You can read more about Visual Language in Robert Horns Book.
