Demand forecasting – what is it?
Demand forecasting is the process of estimating future demand for products or services. The main purpose of demand forecasting is to enable companies to effectively plan production, inventory management and logistics in such a way as to meet customer expectations while minimizing costs. Demand forecasting avoids both excess inventory, which generates additional storage costs, and shortages of goods, which could result in lost sales and dissatisfied customers.
Effective demand forecasting is a key element in supply chain management and plays an important role in ensuring product availability, improving customer service and keeping production flowing. Demand forecasting allows companies to better manage their resources, prepare for market changes and minimize costs associated with unsold goods. With demand forecasting, companies can also better plan marketing campaigns, anticipate periods of peak demand and adjust their offerings to meet customer expectations.
Demand forecasting methods include a variety of techniques, from traditional statistical methods to modern machine learning techniques. Demand forecasting is based on the analysis of historical data, market trends, seasonality, as well as macroeconomic factors such as consumer income levels, market changes, the economic situation or competitors’ actions. Depending on the needs and availability of data, companies can use various forecasting tools, such as moving averages, exponential smoothing, regression analysis or more advanced models based on artificial intelligence and machine learning.
Types of demand forecasting:
- Short-term forecasting – focuses on periods of up to a few months, and is mainly used for inventory management, ongoing production planning and preparation of promotional campaigns.
- Medium-term forecasting – deals with periods of several months to a year and is useful for production planning, resource allocation and strategic supply decisions.
- Long-term forecasting – covers forecasts for more than a year and is crucial for planning business strategy, investing in new technologies, developing new product lines and entering new markets.
Challenges of demand forecasting: Demand forecasting is not an easy task and presents many challenges. Market volatility, the unpredictability of external factors, such as changes in the economy or the actions of competitors, can affect the accuracy of forecasts. Therefore, it is important that forecasts are regularly updated and adapted to dynamic market changes. The more accurate the forecasts, the greater the chance for effective resource management and customer satisfaction.
