From The MODAF Operational Viewpoint (OV) p23:

The OV-4 Organisational Relationships Chart shows organisational structures and interactions. OV-4 exists in two forms: typical (eg a generic brigade command structure) and actual (eg an organisation chart for a department or agency).

From The MODAF Operational Viewpoint (OV) p23:

A typical OV-4 shows the possible relationships between organisational resources (organisations and posts). The key relationship being composition, that is, how an organisational resource makes up part of a parent organisation. In addition to this, the architect may show the roles each organisational resource has, and the interactions between those roles, ie the roles represent the functional aspects of organisational resources. There are no prescribed resource interactions in MODAF; the architect should select an appropriate interaction type from the MODAF Ontology or add a new one. Interactions typically illustrate the fundamental roles and management responsibilities, such as supervisory reporting, Command and Control (C2) relationships, collaboration and so on.

A typical OV-4 can be considered as a special type of SV-1 where the resources shown are purely organisational.

An actual OV-4 shows the structure of a real organisation at a particular point in time, and is used to provide context to other parts of the architecture such as AV-1 and the StVs.

The OV-4, Organisational Relationships Chart, addresses the organisational aspects of an architecture.

A typical OV-4 illustrates the command structure or relationships (as opposed to relationships within a business process flow) among human roles, organisations, or organisation types that are the key players in the business represented by the architecture.

An actual OV-4 shows real organisations and posts and the relationships between them.

MODAF only defines two fundamental relationships between Organisational Resources: structure (whole-part) and interaction (which includes the command relationship). When there is a need for other types of organisational relationships, these should be recorded and defined in the AV-2, Integrated Dictionary.

An OV-4 clarifies the various relationships that can exist between organisations and sub- organisations within the Architecture and between internal and external organisations.

Note that individual people are not modelled in MODAF, but specific posts may be detailed in an actual OV-4.

Configuration History


This view duplicates existing views. As it says itself it is a form of the SV-1 and all the elements you’d use are actually part of a solution not the logical or implementation-free description.

The metamodel doesn’t help - the types of organisational resource are in the System (solution) Viewpoint whereas the more specific instances are in the logical Operational Viewpoint.

Also begs the question why there is no such stereotype as an ‘Actual Role’?
