Performance Assurance activities are either specified in the Code (such as Maintenance of Qualification) or areas identified as priorities for the PAB in the Retail Risk Register. In mobilising for REC V2, the Code Manager completed a risk assessment of the REC V2 schedules along with the REC V3 schedules available at the time. REC V3 covers processes that will operate after CSS go-live, and therefore some schedules are fundamentally different to REC V2, whereas others are unaffected. ************We are currently measuring 27 out of the original 56 identified Risk Drivers. The 29 remainder Risk Drivers have not been measured to date for the following reasons: ****For 3 drivers we are in the process of gathering data, primarily from Prepayment Infrastructure Providers (PPMIPs). ****For 12 drivers relating to prepayment performance we are conducting additional work to determine the optimal way to measure these Risk Drivers. ****The remaining current 14 Risk Drivers relate to relevant measures post-CSS, and will therefore start to be measured and monitored after CSS go-live. *************The proposed changes that have been made to the Retail Risk Register include updates to 16 Risk Drivers, either improving the description or moving them to a more appropriate Risk. A more detailed description of the changes is available in the updates to the REC Retail Risk Register document
