Legacy system
EE ran its ERP estate on legacy infrastructure and hosted it on the premises of a third-party supplier both before and after the merger with BT.
There were no plans for a strategic transformation involving the aging ERP systems. The volume-based operational model, higher time to market, and longer delivery cycles affected customer spending. The overall customer experience was also far from satisfactory.
The challenge: Modernizing EE's legacy ERP
BT realized the value of selecting a suitable partner who could pro-actively be responsible for application management services.
They wanted the partner to also handle the development requirements associated with application management services, drive accountability, and ownership with a time and target-driven transformation of these services.
BT wanted to improve customer experience, reduce cycle time, and measure them with precision through a new solution proposed by their new partner of choice to transform EE's ERP systems.
The solution: SAP HANA on cloud
TCS migrated EE's SAP ERP to SAP HANA infrastructure on cloud.
TCS set up an advanced command center for near-real-time handling of issues and customer triage. The team built reusable assets and enabled predictive spend analysis. Adopting a Kanban approach to monitor operations, TCS substantially reduced the number of defects and defect leakages, improving BT’s customer experience. The team proactively resolved issues, overcame age-old design limitations, and continuously monitored the process chain to reduce the time to market. TCS played a pivotal role in migrating EE’s legacy SAP ERP to SAP enterprise infrastructure on the cloud.
The benefits: A crucial step in ERP transformation
TCS helped the client achieve a key milestone in their ERP transformation journey.
We assisted EE in upgrading the technology stack and migrating their SAP database from Oracle to SAP HANA. EE was able to improve customer experience, ensure RFT, reduce cycle time at a reduced cost, and improve services.
