This makes a very interesting read. Most of the tenets of ACT (anti-conventional thinking) goes against traditional brainstorming or idea generation processes. I guess that is why it is called Anti-conventional.
Though I agree with most of what is being subscribed, I have to say that this is very difficult process to use in a traditional organization.
This needs highly creative and self-assured people, who can take criticism, build on ideas (thiers and others), and trust each other a lot! If any of the above are not present, this could be a recepie for disaster.
This said, I do think that if you want breakthrough ideas, this could be the way to go. Just involve a small team made of people who are self-assured and trust each other, let them go through the process and I am sure, you will get some really amazing ideas.
