Notes:
(1) An evaluation would be required to assess the technical feasibility of updating/streamlining the regulatory guides shown in the figure, including the potential consolidation of guidance documents sharing a common topic.
(2) While not shown in the figure, the potential vision for the I&C regulatory guidance infrastructure allows for incorporating, as appropriate, the current set of digital I&C interim guidance into durable I&C regulatory guidance. For example, DI&C-ISG-04 (Highly Integrated Control Rooms & Digital Communication Systems) could be retired by revising Reg Guide 1.152 to endorse IEEE 7-4.3.2-2016, which captures the information from this interim staff guidance document.
(3) For the development of new standards, as well as the need to endorse IEC standards, an evaluation would be required to determine if these can be endorsed via existing regulatory guides thus avoiding the need for developing new ones.
