Challenge
Assessment and response
Risks identified
- unknown communication paths
- incomplete asset records
- unclear support responsibilities
- weak audit and maintenance evidence
Meridian approach
- reviewed available engineering records
- interviewed site and support teams
- reconstructed known interfaces
- created updated architecture and asset records
Deliverables
- network architecture drawings
- asset register
- interface register
- IP address plan
- documentation gap summary
Outcome
The site team received an improved documentation baseline to support maintenance, risk assessment, upgrade planning, and future assurance activities.
