The Sr. Specialist, Demand Planning sits within Supply Chain Planning and refines future product needs into a unified 15-month forecast by synthesizing inputs from sales teams and customers. This role goes beyond forecast execution — it owns demand signal quality, statistical model design, and the continuous improvement of the tools and processes that drive the consensus plan. Operating across multiple business units with a complex mix of MTS, MTO, and spot demand patterns, it creates a plan that is shared with Supply Chain Planning for operational feasibility and with Finance for budgeting and revenue projections.

• Demand Pattern Segmentation & Statistical Modeling: Lead SKU segmentation across MTS Baseline, Spot, and MTO demand patterns before applying any statistical methodology. Build and maintain multi-variable forecasts to analyze market trends and demand drivers, assessing their potential impact on product needs. Adjust the forecasts accordingly to reflect these insights.
• Consensus Forecast Leadership: Own and facilitate the S&OP Demand Review across all business units. Challenge and reconcile bottom-up and top-down commercial inputs, maintain a quantified upside/downside risk register in volume and revenue terms, and present demand assumptions and scenario analysis directly to senior leadership.

Set and track quarterly continuous improvement targets for accuracy, bias reduction, and planning cycle efficiency.
• Forecast Accuracy & KPI Ownership: Own MAPE, wMAPE, and directional bias KPIs by SKU, business unit, product format, and planning horizon. Design and maintain the KPI reporting framework — not just the numbers — ensuring the organization measures planning quality correctly and acts on the right signals.
• Continuous Improvement & Tool Development: Continuously evaluate and improve demand planning processes, methodologies, and supporting tools. Design and build practical planning tools for cross-functional use. Leverage AI and automation selectively to accelerate tool development and improve analytical output quality.
