A New Group (Scenario)
David had been away from his old company, Control Tech, for a while. He remembered that when he worked there 10 years ago, the company was very traditional and conservative. The lines of authority and responsibility were established and clear. Now, it felt ironic that he was managing the consulting team that was going to help bring a group orientation into being. In addition to the traditional hierarchy, with a manager and subordinates, he saw a need to introduce teams comprised of individuals from various work areas to help solve operational problems. He also felt that for certain projects, there could be groups that could function essentially independently, even taking on traditional management responsibilities such as hiring, planning, and scheduling. Plus, he also saw real potential for special, temporary projects to be handled by groups that would disband once the task was completed.
-All of the groups being considered by David are examples of __________.

A) command groups
B) cross-functional groups
C) self-managed teams
D) informal groups
E) formal groups
