Hearing from everyone and not just pet few.
Once again, talk to everyone and listen to what they say.
Can't think of one since the team was actually only 3 main people and a few ancillary people in other places.
I left the job because of the manager; she didn't trust people and accused people of things without proof. She lacked confidence herself, which contributed to this behavior. She was promoted from basically an admin to a director of an IT specific area without expertise.
