What the buyer is asking for

SONI is seeking to appoint one (1) supplier to act as Client-Side Advisor, providing programme management, technical assurance, test assurance and transition support to SONI in respect of the Corporate IT Separation Programme and the establishment of SONI’s Security Operations Centre, working alongside SONI’s internal programme and technical teams. This procurement is being conducted in accordance with the Procurement Act 2023 (the “Act”) and the Procurement Regulations 2024. The Client-Side Advisor augments SONI’s own programme and technical team, providing programme leadership, technical assurance and delivery oversight of the Systems Integrators (SIs) and suppliers delivering the separation workstreams. The role does not extend to the delivery, implementation or provision of any of the underlying systems, equipment or services being procured under SONI’s other separation competitions. The Tenderer awarded the Framework Agreement (the ‘Supplier’) will act as SONI’s primary partner for Client-Side Advisory services, working alongside SONI’s internal teams and its other external advisors.
