Functional perspective is defined as “a prescriptive approach that describes and predicts task-group performance when four communication functions are fulfilled.” In short, this approach, created by Randy Hirokawa and Dennis Gouran, explains that a group making a decision together is better that a singular mind trying to reach a goal. An example of this approach is present in the movie Set It Off. The group of ladies come together and have a meeting about robbing a bank. They establish the goal and they start thinking of ways to achieve that goal using all of the four functions of effective decision making.
