Here is a site that contains descriptions about creativity techniques:
Below are listed a number of creativity techniques to help with creative thinking. Like most tools these creativity techniques all have their good and bad points. I like to think of these creativity techniques as tools in a toolbox in much the same way as my toolbox at home for DIY. It has a saw, spanner, hammer, knife and all sorts of other things in it, they are all very useful, but you have to pick the right tool (creativity technique) for each job. We will try and provide a little guidance along with each tool to let you know whether it’s best used for cutting paper or putting in nails.
