Accurate demand forecasting leverages historical sales data and market trends to predict future customer demand, helping retailers optimize inventory levels and reduce stockouts. Supply planning focuses on aligning procurement, production, and distribution processes to ensure the right products are available at the right time, minimizing costs and improving service levels. Explore how integrating demand forecasting and supply planning can transform retail operations and boost profitability.
Why it is important
Understanding the difference between demand forecasting and supply planning is crucial for optimizing inventory levels and minimizing costs in retail. Demand forecasting predicts customer purchase behavior using historical sales data and market trends to estimate future demand accurately. Supply planning translates these forecasts into actionable procurement and production schedules to ensure product availability without overstocking. Mastery of both processes enhances operational efficiency and improves customer satisfaction by aligning supply with actual market needs.
