DCC Consultation on proposed SSI enhancements

10 July 2019

SECMP0058 ‘Changes to the governance of the Self-Service Interface’ was implemented on 27 June 2019, making amendments to SEC Appendix AH ‘Self Service Interface Access Control Specification’.

The key change was to remove the low-level detail and functional requirements of the Self-Service Interface (SSI) and move these to a new technical specification document titled the ‘SSI Baseline Requirements Document’. This document is maintained by the DCC and is not subject to SEC Section D ‘Modification Process’. Instead, the SEC Panel or a delegated Sub-Committee will approve all changes being made to the document.

This consultation contains a number of proposed improvements to the SSI which have been raised by SEC Parties and are being considered for implementation. DCC is seeking customer views on whether Parties consider the proposed changes to provide benefits to Users beyond those currently provided by the SSI; and whether the proposed changes may have any impacts on Users’ operational processes that should be considered.

The proposed changes to the SSI as well as the response can be found here.


How can I respond to this consultation?

Please send your responses or any enquiries to SSIRemedyImprovements@smartdcc.co.uk by 17:00 on 26 July 2019.

Any questions can also be directed to SSIRemedyImprovements@smartdcc.co.uk.
