CMOSS0006 Purpose
Information
CMOSS0007 The purpose of the CMOSS Interoperability Requirements Specification is to provide a common, configuration-controlled, Information
Science, Technology, Engineering, Experimentation, Test & Evaluation and Acquisition minimum baseline technical requirements document. This allows US Army (T), and Joint, Interagency, Intergovernmental, Multinational (JIIM) (O), materiel developers and integrators to ensure CMOSS compliant/conformant solutions are over-the-interface(s)-interoperable with other components/systems developed to the same "shalls". This document also addresses the need for the US Army (T), and JIIM (O), to have a mechanism to codify critical, Government interoperability design choices at the 'speed of relevance', in the event that public-private consortium governance processes/timelines would negatively impact Army Modernization. It also allows the Government to add additional specificity above and beyond consortium-based standards in order to achieve the portability and reuse objectives of the US Army. Although there are significant benefits from leveraging Public-Private consortium-based open standards approaches, the Government must always maintain the ability to make and coordinate inherently Governmental decisions in the best interests of the Warfighter. The requirements within this document should be incorporated by reference in contracts, citing the document title, revision number, and effective date of publication. 'CMOSS#####' Unique Identifiers (UID) will typically be linked as 'parent requirements' from which materiel system, subsystem, component, etc. 'child requirements' are derived. This CMOSS Interoperability Requirements Specification is under
