Step-by-step explanation:
The person who identified 10 roles grouped around interpersonal relationships, the transfer of information, and decision making was Henry Mintzberg. He articulated these roles in his management theory, which emphasizes the diverse tasks and responsibilities that a manager must undertake. The roles Mintzberg described range from those that involve direct interaction with others, such as leader and liaison, to those related to the processing of information, like the monitor or spokesperson, to those that involve decision making, such as the entrepreneur or resource allocator.
