What materials are required to support the plan? Do we have the internal and supplier capacity to execute it? Where are the constraints and risks before they impact the customer? What should we stock, how much should we stock, and why? Can our ERP/MRP system provide reliable signals that our team can execute against? Ultimately, success will be demonstrated through measurable improvement in customer OTD, fill rate, schedule attainment, material availability, supplier performance, inventory accuracy, distribution performance, and planning effectiveness, while reducing reliance on expediting and manual intervention.
