I kind of see collaboration as a way to ensure you don't go off on some idea that doesn't align with the rest of the team. In the blog post he mentions that he presents his idea with the team in step 4, isn't that when it becomes collaboration and his idea is potentially scaled back or enhanced? I've seen brainstorming variants where the team thinks for themselves first in silence in the same room and then present their ideas in form of post-it notes. In the end though, people tend to select the safest ideas, but I feel it also depends on how many "radical thinkers" are really on the team.
