Case Study: FarEasTone Telecommunications achieves 50-60% faster data-to-insights and self-service visual analytics with Tableau Software

Far EasTone empowers business users with data visualization software

Far EasTone Telecommunications, a leading Taiwanese telecom and digital services provider, faced a growing data challenge: business users had to route reporting requests through IT to extract datasets from a 20 TB data warehouse, a slow, programming‑dependent process that limited self‑service analysis across departments like call center, finance, sales and marketing.

IT led a strategic rollout of Tableau—building a 16‑person data intelligence team with three Tableau experts, running 150 roadshows and training about 500 users—putting visual, interactive dashboards into the hands of business users (50 daily users, ~200 server viewers). The result: IT now acts as an internal consultant and helpdesk while users perform ad‑hoc analysis, share dashboards on Tableau Server/mobile, handle very large datasets (up to ~500M rows), and cut time from data to insights by roughly 50–60%.
