The NATO Standardization Staff Group (NSSG) assists the NSO Director. It is a personnel-level forum that facilitates the coherence of NATO`s standardization activities and procedures in all NATO bodies, particularly standards bodies1. In 1991, a proposal to establish the NATO Standards Agency was presented, but it was not created. Instead, a civilian personnel standards agency, the Office for NATO Standardization (ONS), was established. The ONS was established in 1994 and implemented in 1995 by the North Atlantic Council.   From 1998 to 2000, NATO formally merged the two agencies MAS and ONS and renamed them NATO Standardization Agency, which served both military and civilian personnel.   The NATO Standards Bureau (NSO) launches, coordinates, supports and manages NATO`s standardization activities under the control of the Standards Committee (STC). It also supports the NATO Military Committee in the development of military operational standardization. Its role is to promote the standardization of NATO in order to increase the operational effectiveness of the Alliance`s armed forces. The NATO Standards Office (NSO) facilitates the participation of standardization planning areas in the NATO Defence Planning (NDPP) process to achieve interoperability.
The NDPP aims to coordinate the national and multinational development of the armed forces and capabilities for all allied missions. Standardization contributions to the NDPP improve the interoperability of these forces and capabilities. The Standards Committee (SC) is NATO`s highest-ranking committee for the unification of the Alliance, composed mainly of representatives from all NATO countries. It works under the control of the North Atlantic Council and publishes policies and guidelines for all NATO standardization activities. Its role is to implement domain governance within the Alliance for Policy and Management of Standardization, in order to contribute to the development of the Allied`s interoperable and low-cost armed forces and military capabilities. NATO standardization is the development and implementation of concepts, doctrines and procedures to achieve and maintain the level of compatibility, interchangeability or community necessary to achieve interoperability. The NSO is composed of military and civilian personnel created to be responsible for both the standardization of the Military Committee and the North Atlantic Council.  It is also the NSO`s responsibility to initiate, manage and adopt a Standardization Agreement (STANAG).  The NATO Standardization Documents Database (NSDD) provides consolidated storage of all NATO standardization documents and related information, including national ratification data. Among the hundreds of standardization agreements (the total number was just under 1300 in April 2007[updated]), are those relating to ammunition, card markings, communication procedures and bridge classification. A Standardization Agreement (STANAG) is a NATO standardization document that establishes the agreement of member states to implement a standard in whole or in part, with or without reservation, to meet an interoperability requirement. The NATO Standardization Office (NSO) (former NATO Standardization Agency, NSA).
In French: NATO Standards Office), it was a NATO agency established in 1951 to provide standardization activities for NATO.  The NSA was born out of the merger of the Military Agency for Standardization and the Office for NATO Standardization.  During the Agency`s reforms, the NSA was transformed on 1 July 2014 into the NATO Standards Office (NSO), headed by the Director of the NATO Bureau of Standards (DNSO).  The standardization products of nato authorities ensure that the Alliance`s armed forces and their exhausting partners can cooperate effectively and effectively.
