Answers and Explanations:
In teamwork, the easiest stage would be the "norming stage."
As the stages of team development start to increase, this stage is at the point where members of a team are feeling that the type or form of project that is being made is becoming familiar, or more well-known to them about the project. The team is now working as more of a unit and is in more of the accepting stage of each other, while getting past each others differences and all of the minor issues and problems that had happened in the starter stages.
Basically, this is the stage of unity among each other as teammates.
I hope that this helps.
