Nick Duffill is one of the leading experts on mind mapping and the use of mindmapping software. I noticed in the Andrew Wilcox Daily that he conveyed some key advice recently at the Bigger Plate conference in the UK, captured in the video below. He makes some extremely important points here in this video on mistakes to avoid if you see to use mind mapping software to communicate in business.
One key take away is that people who develop a mind map see it very differently than those who see it later. If you want to develop buy-in via a map, you need to involve those you want buy-in from in the development of it.
