Demand planning and forecasting are critical components of supply chain management and business operations. They involve the process of predicting future customer demand over a specific period, using historical data, market trends, and other relevant information. This predictive insight helps businesses make informed decisions about production, inventory levels, workforce management, and other operational aspects to meet customer demand efficiently while minimizing cost and maximizing profit. Understanding the basics of demand planning and forecasting can empower organizations to navigate market uncertainties more effectively.

What is Demand Planning?

Demand planning is a multi-step operational supply chain management (SCM) process used to create reliable forecasts. Successful demand planning can help improve the accuracy of revenue forecasts, align inventory levels with peaks and troughs in demand, and enhance profitability for a given channel or product. It involves the systematic use of analytics to predict demand, making it possible for companies to shape their future by making informed decisions that balance demand and supply efficiently.

What is Demand Forecasting?

Demand forecasting, an integral part of demand planning, refers to the process of estimating the quantity of a product or service that consumers will purchase. It uses historical sales data, economic trends, industry-wide comparisons, and other analytics tools to provide an estimate of expected demand. Accurate forecasts enable businesses to adjust their production schedules, inventory levels, and promotional activities to align with anticipated market demands.
