What are the spontaneous and specific mechanisms of governance?

Properly governing an organization is both a challenge and a vital necessity.
In its formal dimension, governance is often associated with bodies such as the board of directors or with functions such as auditing.
In its informal dimension, governance relies on spontaneous and specific mechanisms. The first of these is mutual oversight among executives.
Equally informal, organizational culture helps to disseminate the values, rituals, and collective habits of the group.
