What is Dunbar's Number?

Approximately 150 is the cognitive limit of stable social relationships humans can maintain. Nested groupings of 5, 15, 50, and 150 correspond to intimacy levels.

How does it apply to organizations?

Companies below 150 people often work without formal management structures. Above this, hierarchies become necessary to maintain coordination.
