Identify a student group (a work group is  also appropriate) with which you are familiar. Then, identify all the  ways in which this group interacts with its environment (for example, a  service club may need to recruit new members, work with other groups to  coordinate a large charity event). After that,  you should include  actions from the group to the environment as well as actions from the  environment to the group. You should also focus on how these various  interactions affect the internal operation (throughput) of the group.
