Ad-hoc input-output norms enabled in rule-based IT systems, with RMS referrals and Norms Committee SION recommendations. Amendments authorise Ad-hoc Input Output Norms to be fixed in a rule-based IT environment without mandatory reference to the Norms Committee, with a percentage of RMS-flagged cases referred for Norms Committee validation. Additionally, where ad-hoc norms are arrived at by the Norms Committee, the Committee may recommend notification of Specific Input Output Norms (SION) on a case-by-case basis, streamlining norm fixation and SION notification under the Advance Authorisation Scheme.
