In many cases, the solution to a problem is staring us right in the face. We have all the information we need, we just aren't seeing it correctly. To use a mind map to solve a problem, start by writing the problem in the middle of a large sheet of paper. State the problem as the desired result. "I can't get to Paris" is not a good problem because you will probably end up mapping all the reasons why what you want is difficult. State the problem as "Getting to Paris" helps you move on to thinking of all the ways you can get to Paris.
Draw lines that move away from the problem, and on those lines write the things you think you need to get what you want. Draw lines away from those lines and on them write how to get those things.
As you complete this exercise. you will usually see that some routes to solving your problem are quite complex. Others are relatively straightforward. Mind maps help you by making "easy" answers easy to see.
Have a thorny problem to solve at work? Get a sheet of paper large enough to cover a conference table. At the center of the page write your corporate objective. Keep it simple and short. Hand pencils to key decision-makers responsible for resolving this problem. Have them work together to create a mind map that documents the many ways in which the problem can be solved. This method ensures all ideas, and all possible ramifications of a major change, are heard. As long as the participants understand the process, this will produce a good solution.
