Definition of Demand Forecasting
Demand forecasting is a technique that is used for estimation of what can be the demand for the upcoming product or services in the future. It is based upon the real-time analysis of demand which was there in the past for that particular product or service in the market present today. Demand forecasting must be done by a scientific approach and facts, events which are related to the forecasting must be considered.
Hence, in simple words, if someone asks what demand forecasting is, we can answer that after fetching information about different aspects of the market and demand which is dependent on the past, an attempt might be made to analyze the future demand.
This whole concept of analyzing and approximations are collectively called demand forecasting. In order to understand it more clearly, we can consider the following equation so that we can understand the concept of demand forecasting more easily.
For example, if we sold 100,150, 200 units of product Z in January, February, and March respectively, now we can approximately say that there will be a demand for 150 units of product Z in April. However, there is also a clause that the condition of the market condition should remain the same.
Methods of Demand Forecasting
There are two main methods of demand forecasting: 1) Based on Economy and 2) Based on the period.
1. Based on Economy
There is a total of three methods of demand forecasting based on the economy:
Macro-level Forecasting: It generally deals with the economic environment which is related to the economy as calculated by the Index of Industrial Production(IIP), national income and general level of employment, etc.
Industry-level Forecasting: Industry-level forecasting usually deals with the demand issued for the industry’s products as a whole. We can consider the example where there is a demand for cement in India, Demand for clothes in India, etc.
Firm-level Forecasting: It is a major type of demand forecasting. Firm-level forecasting means that we need to forecast the demand for a specific firm’s product. We can consider the following examples such as Demand for Birla cement, Demand for Raymond clothes, etc.
2. Based on the Time
Forecasting based on time may be either short-term forecasting and long-term forecasting.
Short-term forecasting: It generally covers a short period which depends upon the nature of the industry. It is done generally for six months or can be less than one year. Short-term forecasting is apt for making tactical decisions.
Long-term forecasting casting: Long-term forecasts are generally for a longer period. It can be from two to five years or more. It gives data for major strategic decisions of the company. We can consider the example of the expansion of plant capacity or on opening a new unit of business, etc.
