Essential Functions: Power BI Dashboard Development and Management: Design, publish, and maintain interactive Power BI reports and dashboards for demand, shipments, forecast accuracy, inventory, and customer performance; Connect Power BI to databases, on-premises sources through data gateways, and cloud data sources; configure and maintain connections and scheduled refreshes in partnership with IT; Monitor refresh performance and troubleshoot connection, credential, gateway, and data quality issues; Use SQL to query, filter, aggregate, and join source datasets; use Power Query to prepare data and Model view to create and manage table relationships, cardinality, and filter direction; Apply working knowledge of DAX to create measures and calculated columns for KPIs, forecast variances, trends, and time-based comparisons; Maintain documented KPI definitions, validate report results, and manage appropriate access with business owners and IT. Monthly Demand Forecasting: Develop and maintain rolling monthly forecasts using multivariate methods, including multiple regression and time-series models with multiple business drivers; Incorporate historical shipments, customer ordering trends, seasonality, contract changes, customer commitments, wholesaler inventory, competitive supply disruptions, and product launches into forecast assumptions; Account for backorders, allocations, stockouts, and supply interruptions so constrained shipments do not understate underlying demand; Lead monthly forecast reviews, reconcile statistical forecasts with commercial input, and communicate changes and scenarios to Supply Chain and leadership; Measure forecast accuracy and bias at appropriate product and customer levels, including volume-weighted error measures; use backtesting and variance analysis to improve model performance.
