6. Market Engagement Tom Notman - MOSL

7. Market Engagement – Portfolio Approach Engagement between MOSL & Participant companies is essential to the success of the market opening Primary point of contact with MOSL for all communications, questions, issues and sharing But they are not there as a resource to add to your team Communications channels will be two way Combining confidentiality and commercial sensitivity with effective collaboration is key to the success of this role Supported by PMO I will continually be looking for feedback to improve our engagement

8. Market Engagement Team

9. Working environment Each portfolio manager will be responsible for the engagement with a group of participants in both the wholesale and retail sectors of the developing market and work as an integrated part-time member of each of their programme/project offices NOT London based - Portfolio managers will be mainly working from participant’s premises & Participant’s partner premises – please look after them for me! Will each include current Scottish market participants

10. What a Portfolio Manager can do They are a conduit between your programmes and the MOSL programme They will support you in your preparations for market opening by holding a mirror up to you They can act as a sounding board to provide wider market perspectives They are NOT a resource to add to your team strength They are NOT there to do your job for you They can assist with your preparations but they will NOT be able to provide a MOSL ‘stamp of approval’ for readiness

11. Team Approach This will be a geographically dispersed team that will have more face to face contact with participant teams than with each other. However, we will be by: Regular conference call updates Sharing on the collaboration platform Sharing update notes Just lifting the phone Email Thought/Quote/Photo of the day Monthly full day team meeting that is based in or near one of the participants offices

14. What they will be looking for from you…. Introductions and contacts Initial inductions Introduction to your programme teams Sight of your programme plans Sight of your risk registers They are a conduit between your programme & MOSL Some patience desire to build trust Help to agree and baseline the market readiness data The odd cup of coffee Time…….

15. Market & Company Readiness Martin Silcock - MOSL

16. Market and Company Readiness Plan

17. Purpose of the MCR plan Its purpose is to is build confidence that the retail market is ready for market opening by: – setting out technical implementation approach and requirements (data upload, testing, shadow operation) – what, when, how? – explaining MOSL’s approach to market risk evaluation, reporting and mitigation – explaining how MOSL evaluates and reports on individual company readiness and risk – setting out the process and standards for entry certification – setting out appropriate data quality standards, roles and reporting – explaining the regulatory framework for implementation

18. What to expect Based on the principles agreed by RMOMG Aligned to assurance framework and assurance letters Published alongside MOSL’s first market risk evaluation Reflects your input via portfolio managers and WRG

19. Three issues 1.Updating market data through shadow operation: market processes or one-off uploads? 2.How can customer switching be trialled in shadow operation? 3.How does certification work with retail exit?

27. Volunteers We are looking for 2 Wholesale and 2 Retail volunteers Support CGI in system test prior to release for UAT by Trading Parties Duration of testing From December 2015 to March 2016 Skills & FTEs required Business analysts – understand the MAP Test analysts – to execute the tests as required by the Test Plan Data analysts – provision of data and resolution of data issues Technical support – to understand connectivity (should TPs systems be ready for End to End testing) Types of tests carried out To be determined by the Test Plan Witness testing of CGI SIT testing – supporting the Test Partner Connectivity testing – as part of STS preparations User access and administration How will results be shared? Test Partner to establish test forum Weekly dial in covering key learning points (functionality and data)

28. Volunteers Data Requirements There is benefit in using actual data to test the CMOS through CGI SIT cycles We are asking for support in providing test data sets; initially low volumes (c. 100 SPIDs), ramping up to a representative full wholesaler and retailer data set through the duration of SIT cycles leading to volumes that support a full wholesaler settlement run (for at least one retailer). Must be validated for data quality – supported by data input specs through Data Partner Benefits to the programme for providing the data Provide the MOSL solution early visibility of actual market data (de-risk the assurance activities of the system) – defect detection ahead of UAT Working with the Data Partner (including using their data quality processes), provide the opportunity to see early common data quality issues. Considerations How can the data be anonymised and how will it be safeguarded?
