  CRE Notes

• MA: Discussed on 14th June. Not accepted but postponed. Still unclear whether the connectors suggested by the requirements are the only list of connectors allowed to use (T.Louth). Another major issue is the Acquisition Time, we can't yet agree to that (F.Clarke and H.Schnetler)
• MA: Now Accepted after CCB on 14t June 2022
• FC 02/23 : Getting ready to bring this into DOORS
• FC 07/23 : DOORS entries updated. Asked SEs to check through the flow-down to their requirements.
• FC 08/23 : Checked for TechBudgets and LGSS. No response from other systems yet.
• VFW 10/23: Updated implementation list. Close to being done.
• FC 06/24: Working through implementation list now.
• VFW 2024-09-23: Calum to organise System Engineering Meeting and discuss with Mike about implementing changes in DOORS.
