Infrastructure, Governance & Network Alignment
Engagement Overview
This strategic project involved the technical and operational separation and reintegration of complex enterprise infrastructures during the acquisition of ExxonMobil assets by Savannah Energy. Everyday Communications was commissioned to provide senior technology consultancy, bridging the gap between legacy systems and a modern, scalable future-state network for the combined entity.
Challenge
The primary hurdle was managing the divergence of highly specialised IT environments while maintaining continuous global operations. The project faced stringent regulatory compliance requirements, cross-border infrastructure logistics, and the necessity to uncouple integrated ExxonMobil global shared services without impacting day-to-day business productivity or data integrity.
Approach
- Comprehensive technology due diligence and risk assessment of the target environment.
- Development of a detailed Transition Service Agreement (TSA) exit strategy focused on network independence.
- Design of a new governance framework to align infrastructure with Savannah Energy’s operational model.
- Meticulous planning of cut-over windows to ensure zero downtime for essential services.
Execution & Delivery
- Successfully uncoupled network services from ExxonMobil’s global enterprise backbone.
- Directed cross-functional teams across and internal stakeholders to standardise digital assets.
- Implemented new SD-WAN and cloud-edge security protocols for the merged entity.
- Oversaw the migration of mission-critical ERP systems onto a unified, independent platform.
Results & Impact
- Achieved full TSA exit 15% ahead of the mandatory regulatory deadline.
- Redesigning the infrastructure led to an immediate reduction in enterprise IT overheads.
- Seamless integration of over 500 specialised technical staff into a singular governance model.
- Improved global network latency by 20% through strategic traffic steering and direct cloud peering.
Key Learnings
- Early stakeholder engagement is critical in high-governance M&A environments.
- The flexibility of SD-WAN architecture is a primary enabler of rapid organisational uncoupling.
- Standardising network governance early prevents long-term technical debt after the merger completes.
- Clear communication with OEM partners ensures procurement lead times do not delay cut-over windows.
Conclusion
The ExxonMobil and Savannah Energy technology integration stands as a flagship example of mission-critical consultancy. By aligning world-class engineering with a disciplined project management approach, Everyday Communications ensured that the M&A programme was not just a successful transaction, but a robust technical evolution for the enterprise.
