The Organization Relationships Chart is a hierarchy diagram, which describes the relationships between organizations or resources.
You can model the following elements using the NOV-4 diagram:
▪The hierarchy of Organization Types, the Organizational Posts that report to Organizational Types, and the Roles that Organizational Posts perform.
▪The hierarchy of Actual Organizations, and Actual Posts that report to Actual Organizations.
▪Relationships between Organization types. These relationships can include command and control, coordination relationships (which influence what connectivity is needed), and many others, depending on the purpose of the architecture. These relationships are important to show in an operational view of architecture because they illustrate essential roles and management relationships.
Types of NOV-4 diagrams
You can use the OV-4 organizational chart to build two types of OV-4 diagrams: Typical OV-4 and Actual OV-4.
A Typical OV-4 has Organization Types, Post Types, and Role Types drawn on it. You can use it for the following tasks:
▪Organizational analysis
▪Definition of human roles
▪Operational analysis
An Actual OV-4 has Actual Organizations and Actual Posts drawn on it. You can use it for the following tasks:
▪Identify architecture stakeholders
▪Identify process owners
▪Illustrate current or future organization structures
NOV-4 model elements
You can draw the following resource types on an NOV-4 diagram: Organization Type, Post Type, Role Type, Actual Organization, and Actual Post.
Organization Type
A type of organization.
Post Type
A type of post (or job title).
Role Type
The role that someone plays in the organization. (See Actual Post description below for some more detail.) You should only draw Role Types underneath Post Types in the hierarchy.
Actual Organization
An actual organization. Modeling Actual Organizations and their hierarchy and relationships enables you to identify architecture stakeholders, identify process owners, and illustrate current or future organization structures.
Actual Post
A person is appointed to an Actual Post. That person performs Roles; some (or all) that are normally associated with that Post and possibly other Roles normally associated with other Posts. The combination of Roles that a person performs is considered their Job. A Post and a Role both have Competencies. For example, the Product Manager and the Documentation Manager and a Developer may all have the Competency of posting software on the Support Center. They all perform the Role of Software Publisher.
Resource Interaction Line
Allows you to specify cross-hierarchical relationships between organizational resources.
