Design Governance

Design Advisory Group (DAG) 

The role of the Level 3 Design Advisory Group (DAG) is to oversee, review, consult and approve the development of the end-to-end business processes, system and data architecture that delivers the detailed system design.

DAG is chaired by Justin Andrews. It consists of technical experts from each Programme constituency participant and a representative from Ofgem as an observer.

DAG is the primary decision-making authority for the system and solution design, ensuring that participant perspectives are represented during decision-making, and enabling transparency of design artefacts for impacted constituency groups and stakeholders.

DAG can delegate appropriate tasks and activities to Level 4 Working Groups. Like PSG, it may also receive escalations from lower level groups and ensure consensus can be reached so the Programme design work can progress to plan. It can also advise the PSG and other groups if required.

The DAG Meeting Papers are available below.

Business Process Requirements Working Group (BPRWG)

The role of the BPRWG is to develop the business processes and requirements for the end-to-end MHHS design. The BPRWG enables Industry Subject Matter Experts (SMEs) to come together to review the existing business process maps and requirements, and to work through outstanding questions and issues, to refine these to the next level detail to enable recommendations to the Design Advisory Group (DAG) for approval.
