Mind map

A mind map arranges ideas around one central topic. In the example, "Community workshop" branches into People, Activities, Booking and Access, each with its own sub-topics.
Mind maps are quick to make and easy to change, which makes them great for early brainstorming and for seeing how ideas relate.
They work well as a team exercise, on a whiteboard or in a digital tool, at the start of a project when the scope is still open.
