The best team structure, in my opinion, is depicted by a circle. In the circle, everyone has both a specialization and the potential to lead others. Imagine how powerful the team’s leadership might be when you are not the only one leading.
To create the conditions for others to lead, first, give them a sense of purpose. Why does the team exist, and who do they serve? Second, give them the conditions for doing their best work.
When people do their best work, they will go to unimaginable heights. When people go to new heights, others will naturally want to join them there.
Sounds like leadership to me.
You’ve got this.
