Before the Serve
The setter needs to keep track of her position in relation to the other players on the court and make sure that none of the players are overlapped in serve receive.The setter is never a part of the passing on serve receive so she may start at the net or behind a passer. Once the ball crosses the net, she can move to her position at the net and prepare to set the pass.
Play Development
The setter determines the play the team will run. She has communicated the play to her hitters and is ready to deliver the ball when it is passed. If the pass is good, she has her pick of hitters. She should take note of the other team's blockers and defense and pair that up with what she knows about her own hitters to determine who will get the ball or if she will dump the ball over the net to her opponent's side. If the pass is bad, the setter needs to move quickly to the ball and make an attempt to better the ball by putting it in a position to be attacked by one of her front row or back row hitters. If she cannot get to the ball, she needs to call out to a teammate to let them know that they need to make the second contact.
