Why are some groups more successful than others? Why do some groups achieve high levels of both performance and member satisfaction while others do not?

Think of a group to which you've belonged, and discuss the following points:

Briefly describe the group $($e$.$g$.,$ was it a sports team, club, work group, etc.?$).$

On a scale of $1($poorly$)$ to $10($extremely well$),$ how successful was your group in terms of both performance and member satisfaction? If you rated your group between $6$ and $10,$ describe what made it successful. If you rated your group between $1$ and $5,$ describe what made it unsuccessful. In your response, incorporate course concepts $($see "Preparation" links above$)$ and provide examples.

How did the group$$s leader $($formal or informal$)$ contribute to the group$$s performance and$/$or member satisfaction $($or lack thereof$)?$

Provide one suggestion for how to improve the group's performance and$/$or member satisfaction.
