What is the lowest level of an organization called?

The term "Units" refers to the lowest level of an organization in a hierarchical context. In organizational structures, units can represent individual teams, departments, or divisions that operate within a larger framework. They are critical because they represent the specific, actionable parts of the organization where operations are conducted and decisions are made.

Understanding that "Units" are the foundational components allows for a clearer comprehension of how organizations function as a whole. Units often directly interact with customers or execute day-to-day tasks. This makes them essential for implementing strategies and achieving overall organizational goals.

In contrast, categories refer more to classifications within various levels, organization usually denotes the entire entity as a single unit, and unit groups are typically a collection of units rather than the single, lowest segment.
