Project Executive Summary
A strategic network technology migration programme under Project Lightning to transition the UK cable network from legacy RFoG (Radio Frequency over Glass) to next-generation 10G EPON fibre architecture. The initiative secured an expected £21 per home passed cost reduction and established a future-proof infrastructure capable of 100G upgrades. CAPEX approved: €876,000. The full technical stack included OLT (Optical Line Termination), ONU (Optical Network Unit), DPoEv2 (DOCSIS Provisioning over EPON), WDM, ICOMS, Sigma, Netcool, Remedy, Badger, BOLT, GCOMMS, and Clarity PPM.
Role Executive Summary
Senior Delivery Lead / Programme Governance Owner within the Citi delivery team. Owned the full governance framework for strategic compliance platform migration, coordinating 68 direct stakeholders and global distribution lists of up to 300 recipients, establishing and enforcing GO / NO GO decision gating, escalating and managing iterative Verint patch releases across LAB, UAT, and PROD environments, and defining the comprehensive data ingestion strategy for legacy infrastructure decommissioning.
Deliverables
- Steered a mission-critical enterprise voice recording compliance migration to a handover checkpoint with zero new issues identified, by establishing a formal GO / NO GO production gating process and managing iterative vendor patch releases across LAB, UAT, and PROD environments.
- Navigated the decommissioning of legacy infrastructure while maintaining 100% regulatory recording integrity, by designing a comprehensive data ingestion strategy and synchronizing high-impact migration windows across NAM and EMEA to prevent compliance gaps.
- Architected internal technical remediation actions to mitigate the impact of two Severity-1 production defects: deduplication inconsistency and silence detection failure by deploying a deduplication policy deactivation via respective change record and launching targeted data cleanup initiatives.
- Orchestrated governance and communication for 68 direct stakeholders and global distribution lists reaching 300 recipients across NAM, EMEA, and LATAM, by implementing a weekly asynchronous status reporting cadence to maintain delivery momentum during vendor-blocked milestones.
- Mitigated a ~3-month schedule variance risk by proactively re-sequencing the migration programme from the cancelled January 2024 window to an April 2024 target, ensuring continued alignment of Business, Operations, and ICRM sign-off stakeholders throughout the rescheduled delivery cycle.
