Telecom Analytics Ecosystem Modernization Initiative

This technical report details a multi-year initiative undertaken by a large U.S. telecom provider's Construction & Engineering (C&E) organization to modernize its analytics ecosystem. The initiative aimed to transition from an on-premises, warehouse-centric reporting model to a cloud-based, Data Mesh-aligned architecture. The report outlines the critical role played by Cadmus in migrating over 10 Petabytes of legacy data and processes, re-engineering complex datastores to Snowflake, and transforming the user experience from static reports to near-real-time, self-service analytics. Key objectives included defining data governance standards, modernizing data transformation using advanced technologies, and enabling self-service analytics through structured training. The report also discusses challenges faced during implementation, such as minimal vendor support, and the strategies employed to overcome these challenges, including internal capability building and the establishment of a Data Mesh architecture. The initiative ultimately aimed to enhance agility, improve data quality, and democratize access to analytics tools.
