1. REISSUANCE AND PURPOSE

This Instruction:

1.1.  Reissues reference (a) to implement updated policy and responsibilities for interoperability and supportability of Information Technology (IT), including National Security Systems (NSS), as defined in reference (b).

1.2.  Implements an approach that considers both materiel (acquisition or procurement) and non-materiel (doctrine, organizational, training, leadership, and personnel) aspects to ensure life-cycle interoperability and supportability of IT and NSS throughout the Department of Defense (DoD). This approach ensures that information is available to the Department of Defense in an assured, timely, useable, understandable, and cost-effective manner.

1.3.  Implements an outcome-based, mission area focused process whereby IT and NSS interoperability and supportability requirements for new, modified, and fielded systems are documented, coordinated, implemented, verified, and approved to achieve an integrated, and secure IT and NSS infrastructure supporting global operations across the peace-conflict spectrum.
