Agree with the gist of the article. My most productive work was in a team of three where people had different strengths. The same team got blown up to 10 people and we were doing less - albeit more ambitious work, but a lot of time was wasted with people with same strengths stepping on each other toes. Where we had one person with the need to feel important and do "cool" work, we had three with different views. So methodology was far off from the key thing.
