Organizational Units Have Insides and Outsides
Three types of interlocked structures together comprise the whole organization: (1) the nested set of sub-organizations, the financial containers, and the tree of manager accountability; (2) the interlocked management and specialized teams doing the work; and (3) the individual positions that carry multiple roles acted by the current job holder (a person). These structures all have dimensionality giving them a concrete inside and outside and thus private and public spaces relative to members and non-members.
Real-world entities and organizations have insides and outsides, with inherently different public-private conditions for visibility and transparency; e.g., the planet’s surface and the outside of our building is available to all by satellite photos, my thoughts are accessible only by me
Appropriate public-private boundaries, and public and private to whom, is a matter of context and point of view
 
3D organizations, groups, and positions have 2D surfaces inside and outside. External surfaces are generally public while internal surfaces are generally private to group members or jobholders, e.g., team rooms
