A Tableau Software Case Study
DNA is a Finnish telecommunications provider offering cellular, landline and TV services nationwide, with about 1,700 employees and over €850M in annual revenue. The company struggled with fragmented online and offline customer data and a heavy reporting burden that made it difficult to get a holistic, real‑time view of customer journeys and slowed decision‑making.
By implementing Tableau as a single source of truth and enabling self‑service analytics for 1,000+ users, DNA consolidated disparate data sources into unified, real‑time customer views. The shift cut analysts’ time spent on routine reports, removed reporting bottlenecks, freed IT to focus on high‑quality data sources and training, and gave the business faster, more accurate insights for better decisions.
