These guidelines have been produced in conjunction with the development of the CNRA Operating Plan. The purpose behind this is to establish a systematic and transparent approach to how the CNRA and its subgroups are organised and how the Committee manages and performs its work. Similar to the Operating Plan this is the first attempt to produce such guidelines. The intention is that these guidelines should fit into the hierarchy of documents that govern the work of CNRA. At the top of this hierarchy is the Strategic Plan of the NEA; immediately below that is the Joint CSNI/CNRA Strategic Plan; then follows the new operating plan and the operating guidelines (this document).
