The main idea is to separate in time the process of ideas generation and their evaluation. Every group member generates ideas, others try to improve them, all ideas are being written in a list, and the analysis of the ideas is being made later. Sometimes can be used so called "mute" version of brainstorming – brainwriting, when all the ideas are being written down on a sheet of paper, which the participants pass to each other and write their newly-arisen thoughts.
             You mentally "put on" one of six different hats and think accordingly to the rules of the hat you are carrying. In white hat you impartially analyze numbers and facts. Then you "put on" the black hat and search for everything negative in an idea. After that – yellow hat – search for everything positive. Then – green hat – generate new ideas. When carrying red hat you turn on emotional reactions on the issue. And finally in blue hat you sum everything up.
             Author recommends to put the key term in the center of a sheet and then put all possible associations on the branches outgoing from the centre. You may even put pictures behing. While you are drawing the map you may find new associations as well.
             Author thinks that the main source of creativity is in the search of analogies. First of all you chose an object and draw the table of its analogies. In first column you write direct analogies, in second – indirect analogies (for instance, denial of the first column). Then you confront your purpose, object and indirect analogies. Say, for example, your object is a pencil, purpose – diversification. Direct analogy – volumetric pencil, denial – flat pencil. So in the result we receive a pencil-bookmark.
