About The Position

The Demand Planning Manager leads monthly demand planning and CPFR/S&OP operating rhythms for an assigned portfolio and is accountable for strategic, business-aligned forecasting. The role translates data into business insight, aligns internal and external stakeholders around shared assumptions, and drives actions to improve forecast accuracy, reduce bias, strengthen the demand signal, and increase stakeholder confidence. The Manager leads through the team rather than serving as the primary day-to-day forecaster, ensuring analysts execute disciplined forecasting, system maintenance, reporting, and process standards. The role also oversees sales forecast reporting and goal setting. The Manager leads forecast governance and consensus planning, prepares and facilitates demand reviews, manages performance reporting and improvement actions, and communicates forecast changes, risks, assumptions, and recommendations. The role coaches and holds analysts accountable, delegates routine forecasting and system activities while retaining oversight, and manages team development and capacity. It also ensures accurate Logility and connected data maintenance, establishes repeatable planning standards and controls, and partners with technology and process teams on automation, reporting, system capability, and scalability. This job description is not designed to contain a comprehensive list of required activities, duties, or responsibilities. These may change at any time with or without prior notice.
