Organizational Unit Structure
 
The Group Policy architecture is flexible and allows for many types of design. The guiding principle as you design your organizational unit structure should be to create a structure that is easy to manage and troubleshoot. There are two key reasons to create an organizational unit:
 
    To enable delegation of administration.
    To scope the application of GPOs.
 
In general, do not try to model your organizational unit structure based on your business organization. Rather, design your organizational unit structure based on how you administer your business.

In most organizations, organizational unit structure is likely to fall into one of the following categories:
 
    Flat organizational unit structure: 1 or 2 levels
    Narrow organizational unit structure: 3 to 5 levels
    Deep organizational unit structure: more than 5 levels
