Some groups are neither clearly primary nor secondary but are intermediate with some. features of each. Task groups (or task-oriented groups) are small groups formed to do some task or ser of tasks [Nixon, 1979, p. 18]. They include work teams, committees, and panels of many sorts. Some scholars consider the task group to be the most common form of group in our society [Fisher, 1980, p. 3]. Task groups resemble primary groups in being small, for only small groups are efficient work units. This is why large labor forces are broken down into small work teams. Task groups also resemble primary groups in that interaction is typically face-to-face and informal. But the task-group contacts are impersonal, sentimental, and utilitarian. Members are not much interested in one another as persons and are not concerned with the entire person but just with work performance in task group.
