Love the article but disagree on a couple points. First, the ideal is two where both are creative as they work off each other. You can NOT do the creative part with non creative it is too hard. Tons of miss understandings. If they talk about the session they will explain wrong and cause a lot of angst in the group, division, company, etc. Or explain but not provide the reasons as they might not understand the bigger picture.

A huge issue is if the creative person is not the boss or have very strong Influence it is very difficult to get a non creative on board.

With that said I really enjoyed the article. Plus would not be surprised if others disagree with me based on their own experiences. Think parts could be very individual and dependent on external factors.
