I do Agile coaching. That is, I help teams work in a productive and fun way. Basically it's best practices of iterative and incremental development. Because Agile is a best practices thing and not a standard, we're always interested in how some teams do better than others. A professional colleague has put together an online test where you can measure your personality and then find the perfect team-mates. It's a very similar concept to what the article is talking about. I'm not a believer in personality tests at all, but I wonder if in the aggregate they might be marginally useful for team formation. I've heard some rumors that sports psychologists have been using systems like this for years. So, while personality test X might suck for detailing anything about me as a person, if all 100 people at my company take it, would it help optimize team formation? Even if helps out only 10% or so, it could be worth the investment. Beats me. It's an interesting question. I'm all in favor of calling out the over-sold quackery for what it is, but let's not throw the baby out with the bathwater. There still might be something useful in there, even if it only works by accident.
