It's not unusual to be challenged as an individual member of a team, or one who is responsible for team performance, when the team is new or has multiple competing challenges.
When thinking about engaging in team coaching, a good place to start is asking what you need the team to accomplish and why, as well as what part you play in that process.
If you don't have historical information to pull forward for the team as a whole, determine if you can gain any insight into individual member performance.
