Final answer:
The autocratic leadership style is used in situations where consensus is unlikely, quick decisions are needed, or there is a need for expertise. The leader makes decisions without much input from the group.
Step-by-step explanation:
The autocratic leadership style is used in situations where it is unlikely that the group will reach a consensus or when a decision needs to be made quickly or informed by a high level of expertise. For example, an autocratic leader might be necessary in a crisis situation where immediate action is required. Additionally, the autocratic style may be used when the task and outcome are relatively simple and defined, and a number of options need to be considered. In these situations, the leader issues orders and assigns tasks without much input or feedback from group members.
