Definition of Interoperability

• The ability of two or more systems or elements to exchange information and to use the information that has been exchanged.- IEEE Standards Information Network. IEEE 100, The Authoritative Dictionary of IEEE Standards Terms, Seventh Edition. New York, NY: IEEE, 2000

• The ability of systems, units or forces to provide services to and accept services from other systems, units or forces, and to use the services so exchanged to enable them to operate effectively together.- Department of Defense. Joint Pub 1-02, DoD Dictionary of Military and Associated Terms. Washington, DC: 2001.<http://www.dtic.mil/doctrine/jel/new_pubs/jp1_02.pdf> (2001).

PAID AttributesP- Policies and procedures govern a

system’s development.

A- User-based application programs perform or support a specific set of processes and procedures.

I- Infrastructure required to support the system operations.

D- Data and Information structures used to support both, the functional applications and the system infrastructure.

Interaction between two programs

• Programmatic interoperability exists between program offices• Constructive interoperability exists between organizations• Operational interoperability exists between system

Problems with interoperability

• Complexity

• Inconsistent standards

• Lack of centralized or coordinated ownership

• Legacy

Recommendations

• User-oriented systems

• Unified model of interoperabilitywith characteristics like coupling, heterogeneity, synchronicity, ownership, usage patterns.

• Increasing the degree of connectivity and flexibility between systems
