Bouygues Telecom is one of France’s leading telecom providers, serving over 27 million customers through an extensive mobile and fixed-line network. As data volumes and operational complexity increased, the company recognized the need for a clearer and more consistent approach to managing its data assets across teams.
To support performance, regulatory requirements, and cross-functional collaboration, Bouygues Telecom launched a data governance initiative aimed at centralizing knowledge, improving traceability, and fostering company-wide adoption.
A core principle guided this transformation: trusted customer data must be accessible, traceable, and governed at scale.
Challenges
Bouygues Telecom’s complex ecosystem created several governance challenges:
- Fragmented data knowledge across departments
- Limited visibility into data flows and transformation processes
- Difficulty tracking sensitive data, including personal and usage information
- Need for consistent governance across virtualized systems
- Ensuring adoption beyond data and IT teams
- Aligning operational teams around shared definitions and standards
The organization needed a scalable platform capable of structuring metadata, ensuring traceability, and encouraging widespread collaboration.
