• Own and drive on-time delivery (OTD) through strong planning, scheduling, and execution rigor.
• Lead daily operations with a focus on Safety, Quality, Delivery, Inventory, and Cost (SQDIC) performance.
• Conduct daily Gemba walks and operational reviews, identifying gaps between plan and execution and driving rapid problem-solving.
• Ensure alignment between production schedules and floor-level execution, adjusting plans as needed based on real-time conditions.

Financial & Resource Management

• Align staffing plans and labor strategies to demand forecasts and production plans.
• Participate in forecasting cycles and ensure financial implications of planning decisions are well understood and managed.

Leadership & Talent Development

• Build strong planning and operational capabilities within the organization through coaching, development plans, and succession planning.
• Foster a culture of accountability, transparency, and cross-functional collaboration.
• Lead through influence, trust, and clear communication across all levels of the organization.

Continuous Improvement & Transformation

• Lead initiatives to improve planning maturity, including systems utilization (ERP/MRP), data accuracy, and decision-making processes.
• Serve as a key leader in technology implementations and process transformations impacting planning and operations.
