This document provides an overview of sales and operations planning (S&OP). S&OP is a collaborative planning process that aligns all business functions to a single plan to meet market demand profitably. It differs from traditional functional planning approaches by taking a holistic view of demand, supply, and financial plans. The S&OP process involves gathering data, demand planning, supply planning, pre-meetings, and executive meetings to align plans and resolve issues. Critical success factors include top management involvement, structured meetings, cross-functional participation, and integrated planning technology. Benefits include improved profitability, inventory management, and communication across business functions.
