Level 4 is the ultimate goal of information systems seeking interoperability across functional activities and informational domains (Intelligence, C2, Logistics, etc.). At this enterprise level, information is shared globally through a distributed information architecture. Applications and systems operate as necessary across all the functional data domains. The "virtual" workspace uses shared applications operating against an integrated information space. This level represents the capabilities necessary to achieve concepts proposed in DoDs "Joint Vision 2010" documents.
- Procedures enterprise level Joint/DoD procedures, based on enterprise level understandings of tasks such as the UJTL.
- Applications integrated into the common distributed information space. Multiple users can access the same instances of enterprise wide data.
- Infrastructure global networks that support
multi-dimensional topologies. These networks may have different areas based
on security or access control, but they are integrated appropriately to
support the users needs. Current efforts to support Secret and Below
Interoperability (SABI) and guards or filters that support multiple security
levels are examples of this infrastructure.
- Data enterprise data models support the
integration of applications. There is a common understanding of the data
across the enterprise.
