I joined the team 2 months ago as a manager and I have a few teams in my organization. I noticed that each team relies heavily on 1 to 2 people.
Every decision goes to a few people. Production incidents always go to the same group of people. Even some basic questions have to go to these same group of people.
For a historic reason, they have been with the team from the start and they know a lot. However, I see it as a risk to rely on such a few people.
How can I change these teams to be A-teams instead of relying on a few people?
