Which of the following statements regarding group decision making in the workplace is true?

A) Teams are often responsible for making decisions that previously had been made by individual managers.
B) Most important decisions in organizations are made by senior individuals.
C) The prevalence of semiautonomous and self-managed work teams has remained more or less constant.
D) In the U.S., 30% of Fortune 500 companies have at least half of their employees working in teams.

Teams are often given the responsibility of making decisions that were previously made by individual managers. This is because teams are able to bring together diverse perspectives and expertise, which can lead to better decision making.

B is incorrect because while senior individuals may have influence in decision making, important decisions are often made by teams or groups.

C is incorrect because the prevalence of semiautonomous and self-managed work teams has actually been increasing in recent years.

D is partially correct, but the actual statistic is that around 50% of Fortune 500 companies have at least half of their employees working in teams.
