Welcome to Xoserve’s CSS page. This is the central reference point for our customers on Xoserve’s involvement in, and perspective on, the delivery of Ofgem’s Central Switching Service.
We are committed to keeping our customers fully informed on the delivery of this programme. On a weekly basis, we’ll share our Weekly Progress Report, our Day After Reports (DARs) and our updated view on key risks:
- Our weekly Switching Programme Status report; this is the weekly report we’re required to submit to the System Integrator, and we’re sharing here for our customers to have the same update
- Day After Report summaries of key program meetings; these are basic notes that we capture during meetings to share with internal to help with consistent knowledge levels across Xoserve, and to provide a contact point if more information is required. We felt that our customers would benefit from seeing these notes should you wish to understand more about Xoserve’s interactions with the programme.
- Summaries of the key risks: this is a summarised version of our risk log of topics we believe are affecting the programme and the work that we’re doing to address these risks.
Going forward, we’ll look to widen the information we share based on what our customers are asking to understand. If there are additional updates that you would like, or if you have a comment about any aspect of the programme, please contact Emma Lyndon
CSSC Programme Summary: 13th September 2019
Xoserve continue to work closely with Netcompany (SI) to go through the latest version of CSS Integrated Plan (CSSIP) during a workshop held on the 11th September. This session was aimed at addressing concerns raised by Xoserve. The DAR for this meeting will be published early next week.
Version 7.0 of Landmark physical design and the Code of Connection V0.4 has been presented to the Industry and discussed at the Ofgem Design Forum on Tuesday 11th September along with all ESPs secondary interface design. As you are aware from previous summaries and our key risks, Xoserve had highlighted a high priority issue surrounding the requirement for multi webhooks per Organisation in order for prioritisation and processing of key events. This was approved within the Design Forum for inclusion as part of the CSS Interface Design. Some minor amendments to the CSS Interface Design were also approved at this session. All Switching Programme design documentation has now been recommended for approval by the Switching Programme Design Authority.
The second SI technical data working group was held this week on Tuesday 10th September. This focussed on the detailed data scope for migration from ESPs to CSS. This forum will continue to meet on a weekly basis.
For Xoserve’s consequential programme, our design, build & test activities continue to progress to plan. Our last Industry detailed design session is being held on the 23rd September. Our first change packs will be released in line with our change governance for industry consultation on the 16th September. Preparatory activities continue for upcoming internal & external test phases.
