What would you do to improve the effectiveness and functioning of the team?

Scenario Three:

You recently were appointed leader of an existing team of which you were not an original member. After your first few meetings with the team, you left feeling like nothing was accomplished during your time together. Team members showed up for the meeting late, no decisions were reached, and you had a general sense that no one wanted to be there. What are some things that are wrong or missing from this team process? What would you do to improve the effectiveness and functioning of the team? What steps or actions need to be taken in order to do so?
