What is Forecasting?

Forecasting is a technique for making predictions of the direction of future trends based on the analysis of past and present data. Businesses use forecasting to determine how to allocate their budgets or plan for expected expenses for an upcoming period of time. 

Basically, it is a decision-making tool that helps businesses cope with the impact of the future’s uncertainty by analysing historical data and trends. It is a planning tool that enables businesses to chart their next moves and create budgets that will hopefully cover whatever uncertainties may occur.

Forecaster uses data for carried out forecasting methods can either get from primary sources or secondary sources.

  • Primary sources: Primary sources provide first-hand information, gathered directly by the person or organization that is doing the forecasting. They usually collect the data from various questionnaires, focus groups or interviews and, although all the information is difficult to gather and integrate, the direct way of acquiring the data makes primary sources the most trustworthy.
  • Secondary sources: Secondary sources provide information that already collected and processed by a third-party organization. Receiving the data in an organized and arranged way makes the forecasting process easier.

Features of Forecasting

Here are some features for making a forecast:

1. Involves future events

Forecasts are created to anticipate future possibilities, scope, etc making them important for product planning.

2. Based on past and present events

Methods of Forecasting

Companies choose between two basic techniques when they want to predict what can happen in the future. They are- qualitative methods and quantitative methods.

1. Qualitative method

We have also known the qualitative method as the judgmental method. Qualitative forecasting offers subjective results, as it consists of personal judgments by experts or forecasters. Forecasts are generally biased because they are based on the expert’s knowledge, experience, and rarely rely on data.

One example is when a person forecasts the outcome of a football game, which is based more on personal motivation and interest.

2. Quantitative method

The quantitative forecasting method is a numerical process, making it consistent and aim-oriented. It drives away from relying the results on opinion and intuition, instead of utilizing large amounts of data and figures that are interpreted.

There are four main quantitative forecasting methods you can use to determine future sales values, revenues, expenses, costs, trends, and other identical indicators. They are:

  • Straight-line method: This is the simplest forecasting method, both to learn and to follow. It’s typically used by financial accountants to determine future revenues based on past trends and figures.
  • Moving average: This technique determines the underlying pattern of a dataset to predict future values. The most widely used types are the three-month and the five-month moving average.
  • Simple linear regression: Simple linear regression is specially useful when analyzing the connection between different variables, to get a more accurate forecast.
  • Multiple linear regression: we mainly used Multiple linear regression for forecasting revenues, in situations where two or more independent variables are needed for a forecast.
