What do we call a group that is specifically structured for high efficiency?

A group that is specifically structured for high efficiency is referred to as a formal organization. Formal organizations are characterized by a defined hierarchy, clear rules, and established procedures that are designed to accomplish specific goals effectively. These organizations rely on a division of labor and an organized way of coordinating activities to ensure that tasks are completed efficiently and systematically.

In contrast, informal organizations are more loosely structured and emerge naturally within formal settings, focusing on interpersonal relationships rather than efficiency. Social groups can be broader and may not have the same level of structured operations designed for efficiency. A community typically refers to a larger social structure where individuals live or interact, but it does not inherently imply the efficiency focus present in formal organizations. Thus, the emphasis on structured processes and goals in formal organizations makes this the correct choice.
