Case Study: Major UK Telecommunications Provider achieves accurate revenue attribution and trusted executive reporting with Ataccama ONE

Major UK Telecommunications Provider - Customer Case Study

Major UK Telecommunications Provider engaged Ataccama to address poor customer contract segmentation and unreliable executive reporting. The telco needed to centralize reference data, define and operationalize a multi-level customer segmentation hierarchy, and deploy an easy-to-use GUI so business users — not IT — could maintain reference data. Existing issues included missing and duplicated data, low data quality, and slow, untrusted reports that prevented informed decision‑making.

Ataccama implemented Ataccama ONE to build a central reference-data repository, enrich and segment customer contract records, and provide a data‑steward friendly GUI. The solution produced accurate weekly executive reports, linked revenue to specific contract categories (accounting for millions of pounds in revenue), reduced IT costs by shifting maintenance to business users, and enabled faster, more reliable responses to reference‑data changes.
