Which role is not typically found in task-oriented groups?

The role of a historian is not typically found in task-oriented groups because such groups primarily focus on achieving specific objectives or completing tasks. The roles within task-oriented groups are primarily functional and revolve around the immediate needs of the group in terms of productivity and communication.

The note taker is essential for documenting discussions, decisions, and action items, ensuring that all group members have access to important information. The facilitator guides the group process, ensuring participation, managing conflicts, and helping the group stay on track to meet its goals. The timekeeper plays a critical role in managing the group's time efficiently, ensuring that discussions adhere to set time limits, which is crucial for maintaining momentum and productivity.

In contrast, the historian role generally involves looking back at the group's past and recording its development over time, which is not a priority in task-oriented settings where the main focus is on current tasks and objectives rather than reflecting on historical aspects.
