We have recently been supporting the team at the GRI to establish a governance structure around the implementation of focussed actions that will support performance to improve; performance did see a significant and sustained dip but this is starting to show improvements. The latest weekly data shows that performance at the GRI against the 4 hour target has improved by over eight percentage points since week ending 2 July 2017, with the latest published weekly stats (w/e 30 July) showing performance at 92.0%.
