At Wittur Group, a multi-country BI transformation had stalled: planning benefits were not materialising because fragmented data sources and local experience — subsidiary Excel models versus central and local BI systems — were preventing a coherent single source of truth.

As Head of Global BI Centre of Excellence, stabilise the data flow into the Hyperion planning layer and restore board-level visibility across intercompany data — within a 10-day intervention window.

Diagnosed root cause as data flow fragmentation, not tool failure; used Oracle BI ETL tools to stabilise data pipelines; designed and executed structured adoption and communication plans for all stakeholder layers including CEO, CFO, COO, and regional Managing Directors along with Finance teams; and established a Single Source of Truth integrating all subsidiary datasets across the group.

Board-level intercompany data visibility restored within 10 days of collection. Consolidations completed for holding’s figures for shareholders.
