There are different ways of being a team, but by far the best is way is the creative way, where every member of the team has a hand in creating a piece of what the team is making. You could be an implementing team, following the instructions of the creative person–you could even be the creative person who throws your creation over the wall to the rest of the team–but that doesn’t seem like as much fun as being a team where everyone is a creator.
It will take more time, and it will expose you to more discomfort, but being a creator on a team of creators is worth it. Making your team work that way is an investment in everyone’s leveling up, because everyone on the team gets to watch the others do creative work.
Half of what I know how to do I learned on creative teams.
