During the past five years I have been immersed in creative thinking resources and reviewed many books on tools for generating ideas. I’ve synthesized and adapted some of the best practice tools that are out there and create some new ones as well. We have tried this system of ideation tools out with brainstormers and I’ve taught it in my Brainstorming Techniques Webinar Program. The recorded webinars facilitate you through the process. I enjoy most doing live webinars or workshops on this too. Here are some of the best books I recommend on using thinking tools for generating ideas.
Think Better: An Innovator’s Guide to Productive Thinking
Thinkertoys: A Handbook of Creative-Thinking Techniques (2nd Edition)
Conceptual Blockbusting: A Guide to Better Ideas
Creative Whack Pack
KnowBrainer Accelerated Innovation & Creativity Tool by Solutionman v4.0 (Innovative & Creative Thinking Tool Kit)
How to Get Ideas

It is good to build a library of these ideation books to use in your work. Many of these books are all inexpensive and highly rated on Amazon. I’ve included the price in the image so you can compare cost for building your library.
