In more than thirty years of developing software and of managing others who do, I can tell you that "this is a pipe dream." This is "wasting time standing in front of a white board, sticky notes in hand, just because someone else said that you should do it." It is also advocating that each "team" (sic ...) member gets to decide for himself what he wants to do, and that everything that is to be done can be done in one day. That's not reality.
How would you feel if you were paying for someone to build or remodel your house, and you saw the crew standing around a white board with sticky notes, apparently trying to figure out what to do next? Uh huh.
A "team" engages in "team work." They work together to determine what is to be done, what is the best way to do it, and how to divide each task so that several people working simultaneously can advance the project faster than any one of them could do so if working alone. (And there was an architect involved, too.) The description and work-breakdown of any task might involve many pages and dozens of steps. It might take many weeks to complete, with development and planning always overlapping. Project management is a full-time occupation – the managers do not write software.
"There is no such thing as a 'Team of One.'" When you have that, you have "lone wolves." People who try to own "their" piece and to do without communicating or working with their so-called "teammates." Lots of developers seem to like it this way and to expect it to be this way – until they first find themselves in a situation where "many hands do make light work." Then, the white-boards and the sticky notes quickly go away. They're replaced with detailed design documents, productive meetings, explicit time and status recording, and Microsoft Project.®
Now, when you watch that team on the field, you see a team, not a dozen guys all fighting for the same football. Not people trying to figure out what the game is while the ball is in play. People who have been part of a truly successful, well-managed team don't want to be lone wolves anymore, because they can plainly see how their working lives just got a whole lot better. It works.
