Company's organizational chart

"An organizational structure defines how activities such as task allocation, coordination and supervision are directed towards the achievement of organizational aims. It can also be considered as the viewing glass or perspective through which individuals see their organization and its environment.
Organizations are a variant of clustered entities.
An organization can be structured in many different ways, depending on their objectives. The structure of an organization will determine the modes in which it operates and performs.
Organizational structure allows the expressed allocation of responsibilities for different functions and processes to different entities such as the branch, department, workgroup and individual.
Organizational structure affects organizational action in two big ways. First, it provides the foundation on which standard operating procedures and routines rest. Second, it determines which individuals get to participate in which decision-making processes, and thus to what extent their views shape the organization’s actions." [Organizational structure.

This AD diagram example was redesigned from the picture "Single root domain with a structured OU model" from the book "Active Directory for Dummies".
"A domain is the cornerstone that you lay whenever you create trees and forests. Regardless of whether you design a tree or a forest, the starting point is always the root domain. The root domain is the first domain that you create in your AD structure, and it sits at the top of your diagram.
The root domain of your tree, similar to any other domain, is a grouping of
resources built on the following components:
(1) Domain controllers.
(2) Security policies. ...
For many small and medium-sized companies, a single root domain with a
structured OU (organizational unit) model... provides sufficient flexibility for an AD tree. ...
However, larger companies, companies with complex organization charts, and
companies with multiple sites often find that a single domain isn’t suitable." [Steve Clines and Marcia Loughry, Active Directory® For Dummies®, 2nd Edition. 2008]
