I can remember years ago, when working on my business degree, we learned about team development. However, I can't recall what the stages are. It may help me to survive in this chaos. Members of teams come together to form and a politeness exists initially. After a few meetings, people began to vie for position and the storming begins, however quietly.
Folks understand the task but there is usually uncertainty as to how to proceed.
Finally people become comfortable in their role and norms are established that everyone can live with and the group begins to perform its duties with everyone understanding their roles and the task ahead of them. If the team is a task force with a beginning and ending, it will transform itself by ending or evolving into a new group with new responsibilities. In an intact team that is performing, any changes in staffing can move the group back to a storming stage. Sometimes groups are stuck and need to resolve issues that affect their ability to work together. Once you understand the process, it's easier to be a part of the team.
