• Improve forecast performance through ongoing management of forecast accuracy, bias, demand variability, and planning assumptions.

• Translate demand plans into long-range supply, capacity, and constraint models, identifying risks, bottlenecks, and opportunities across a 12–18 month horizon.

• Partner with Operations, Materials, Procurement, and global sites to align supply capability, intercompany planning, and short-term S&OE priorities.

• Prepare and lead Executive SIOP reviews, providing clear recommendations on demand outlook, supply gaps, revenue risk, inventory trajectory, and key business decisions.

• Align operational plans with financial commitments, Annual Operating Plan (AOP) targets, and broader business objectives.
