To start, I'm pretty biased on this topic, but I still believe that teams can and will provide a valuable resource in years to come. I can't tell you how many times I've heard my friends jump ship at their company to work on a project or join another company as a whole team. They do this because they've worked together, they have a good understanding of HOW they work together rather than their specific skills. As an experiment I created a team with my own startup consulting with those I wanted to. I didn't do it because they had the best skills I knew of, I did it because I knew I could work with them. Their personalities and my personality worked in a way that if they disagreed, I knew they did in the right mind set.
The Table Group has a great book about "The Ideal Team Player," that mentions what an effective team member can look like, but ultimately I think it is about the personalities and the relationship they bring. This is very much like the Psychological Safety that a comment above had.
Again I am very biased, as I even founded a company about teams to better understand how to help them and support them in today's workplace (goelevator.com).
I would rather work with someone that can learn from me or I can learn from where the personalities are conducive to success rather than a skilled person that I will never mesh with.
