  • Sanofi
    Supply Chain
    April 2024 - October 2024 (6 months)
    Paris, France
    Problem: A fragmented Power BI ecosystem, reports piled up without usage logic, and Supply Chain management unable to provide cross-functional oversight.
    › Audit of the existing system: mapping of the report inventory, identification of duplicates, blind spots, and unreliable metrics.
    › Usage-oriented redesign: reconstruction of dashboards around the decisions to be made, not the available data.
    › Automation of preparation flows via KNIME: elimination of manual processing workload, data available without human intervention.
    → Value created: Supply Chain management making decisions based on a unified, real-time, cross-functional view, without data intermediaries.
    › Stack: Power BI
