The challenge
What needed to change
After Vodafone Italy was acquired by Swisscom, the two operators needed to combine customer-data workflows without creating fragile point-to-point integrations or slowing frontline channels.
The approach
How the team responded
The teams modernized their Customer 360 platform with BigQuery and Spanner. Spanner became the managed serving and governance layer, while Spanner Graph mapped lineage and Gemini generated code documentation.
Key takeaways
A shared service layer avoids custom integrations for every channel.
Data lineage makes dependencies visible before changes reach production.
Generated documentation reduces manual maintenance overhead.
