, Differences Between Demand and Quantitative Forecasting Methods
Demand forecasting methods are primarily concerned with predicting the quantity of a product
or service customers will want to purchase, while quantitative forecasting methods are a
broader category of statistical techniques used to make future predictions based on historical
data.
Demand Forecasting: This is a domain-specific type of forecasting used in business
and economics. Its goal is to estimate future sales and customer behavior. Methods often
involve market research, expert opinions, and historical sales data to understand
consumer trends and market dynamics.
Quantitative Forecasting: This is a mathematical and statistical approach that uses a
variety of models to analyze historical data and extrapolate future trends. It is data-
driven and objective, relying on numerical information rather than qualitative factors
like market sentiment.
Relationship Between the Two Approaches
The relationship is one of inclusion. Quantitative forecasting methods are a subset of
demand forecasting. When a business forecasts demand, it can use a variety of techniques.
Some of these techniques are quantitative (relying on numbers and historical data), while others
are qualitative (relying on expert opinions, surveys, etc.). Therefore, all quantitative forecasting
methods can be used for demand forecasting, but not all demand forecasting methods are
quantitative.
Five Demand Forecasting Methods
1. Survey of Buyers' Intentions: This method involves directly surveying potential
customers in rural KZN to understand their plans for building and construction. This can
provide valuable insights into future demand for materials.
2. Delphi Method: This method involves gathering and anonymously collating the opinions
of a panel of experts, such as construction contractors, local government officials, and
building material suppliers in KZN. The process is iterative, with feedback from each
round influencing subsequent opinions, leading to a more accurate consensus forecast.
3. Sales Force Composite Method: This method aggregates the individual demand
forecasts from each salesperson covering the rural KZN regions. As they are in direct
contact with customers, they can provide a ground-level view of demand.
4. Market Research: This involves conducting a detailed study of the rural KZN building
materials market to understand factors like population growth, new housing projects,
government infrastructure spending, and competition. This provides a holistic view of the
market.
