Case Study: KB Kookmin Bank achieves a data-driven culture and cuts 10,000 reporting hours a year with Tableau Software

KB Kookmin Bank leads data culture with Tableau

KB Kookmin Bank, Korea’s largest retail bank, needed to move from IT‑dependent reporting and manual SQL work to a true data‑driven culture so business teams could make faster, evidence‑based decisions. The bank faced slow, repetitive reporting processes, limited report formats, and low data literacy across departments that constrained analysis and timely responses to changing market conditions.

KB implemented Tableau as a visualization‑based self‑service BI platform, with PLAN‑iT supporting deployment and training, and rolled it out enterprise‑wide—including branches and executives. The solution automated reporting, put real‑time dashboards in users’ hands, and empowered non‑technical staff to analyze data; results included a 10,000‑hour annual reduction in reporting time, report cycles cut from weeks to 2–3 days, and faster, more agile, data‑driven decision‑making across the organization.
