Case Study: M-net achieves faster visual break-even analysis and increased profitability with Tableau Software

M-net unlocks new potential and increases profitability

M‑net, a regional telecom serving roughly 380,000 households and businesses in southern Germany with telephone, internet and TV, faced rising competitive pressure and a complex mix of owned and rented network infrastructure. Calculating profitability by customer, line and region was slow and error‑prone—manual spreadsheet work pulling from many disparate sources meant analyses were outdated quickly and it was hard to spot under‑performing areas or make timely investment decisions.

M‑net built an “Expansion Cockpit” in Tableau to consolidate data from its Oracle warehouse and other sources, visualize network topology and map KPIs down to main distribution frames and individual connections. The dashboards cut profitability analysis from days to a few clicks, gave teams instant transparency to identify and remediate unprofitable areas, improved investment and capacity decisions, and created a measurable boost in responsiveness, competitiveness and long‑term profitability.
