In many organizations, the problem is not that people aren't coming up with new ideas to get things done - the problem is keeping track of them so you can follow through with them.  Getting a group of people together to brainstorm a solution is a great idea, but if no one is capturing and organizing the thoughts that are presented, then it is as if they were never presented to begin with.  One way of resolving this is by using the technique of "mind-mapping."

A mind map is simply a diagram that is used to represent any number of words, ideas or tasks that are linked to a central idea.  It can be a much more effective way of tracking ideas than using an outline or just taking notes because it helps to better connect ideas together.  A map can either be very simple with multiple central ideas and single "spokes" to convey ideas attached to that central idea or a map can be more complex with ideas that branch off in further idea sequences from the central idea.  However you use the map it helps to connect the ideas together in a way that doesn't happen with just making a list.  

There is no one set way to do a mind map.  Some people will freehand draw a map while others like to have something that is more structured.  There is also software that is designed to help with keeping your mind map organized and can let you print and/or share with others in a variety of ways.  You can find a list of some of the software at http://en.wikipedia.org/wiki/List_of_mind_mapping_software
