        1. Product nature

        The production period of a product is very influential. For example, if a company’s product has a long or short period of time to survive in the market.

        4. Level of competition.

        Types of Forecasting

        Of course, forecasting has several types. The following is an explanation of those various types:

        1. Based on time

        First, forecasting methods are based on time. This method is divide into three, namely:

        • Long-term, namely forecast that uses analysis for a longer time usually lasts for more than two years.
        • Medium-term, with a period of three months to two years.
        • Short-term, with a period of zero to three months.

        2. Based on function

        Based on its function, according to Heizer and Render (2009: 47), planning for future operations, forecasting is divide into three types, namely:

        Economic forecasting “economic forecast”.

        Focus on predicting inflation rates, availability of money, funds needed to build housing, and other planning indicators.

        Forecasting technology “technological forecast”.

        Pay attention to the level of technological progress that can launch exciting new products that require new plants and equipment.

        Forecasting demand “demand forecast”

        Forecasting aims to determine the forecast of demand and market conditions.

        3. Based on data availability

        The availability of data will determine how the forecast can be done. The types or based on data are as follows:

        Qualitative Method

        The company or organization does not have sufficient data to analyze. So the forecasting results will also be very subjective because the results of the analysis are different. For instance from qualitative methods: Investigations, interviews, discussions.

        Quantitative Method

        Whether the company or organization has sufficient data, usually the method that they will use is the quantitative method. Where in the process of analysis using data and numbers approach.

        Forecasting Method

        As we have seen in the previous explanation, there are two types of forecasting based on the availability of data:

        Qualitative method

        Qualitative methods are used when the organization or company does not have data in the past. Either because the data is not feasible or does not match what you want to predict. Above all, Forecasting is usually based on intuitive thoughts, opinions, and knowledge and experience of the compilers. Qualitative is also based on the results of investigations such as salesman opinions, sales manager opinions, expert opinions, and consumer surveys.

        The following are the most common qualitative methods:

        Market Survey

        This method conducts surveys to consumers, stakeholders, or investigations of practitioners and even competitors. Moreover use a Survey App to make your company’s surveys simpler, automated, and effective. 

        Delphi method

        This method uses a group of experts from various backgrounds to come together to provide opinions in a systematic way.

        Personal Insight

        This personal insight is a simple forecasting method and is no longer used by large companies. In addition, this method is used by discussing or seeing references from people who are experienced and experts in their fields.


        In the consensus method, participants attend open discussions. This is the opposite of the Delphi method. As a result of this consensus, methods are highly biased. Therefore, many large companies have abandoned this method.

        Quantitative method

        The quantitative methods companies or organizations use when they have sufficient data. Further, this method is the process of analysis using the data and numbers approach. The following are types of quantitative methods:

        Time Series Method

        The time series method is a method that uses analysis between the variables to be predicted with the time variable.

        Cause and Effect Method

        This method is based on the relationship between the estimated variables and other variables that influence it. However, the variable is not in the form of time. Understanding cause and effect in business is akin to understanding the ripple effect in a pond; each action creates a series of reactions, often unseen but always impactful.” says Milosz Krasinski from Chilli Fruit.


        To sum up, That’s an explanation of forecasting, from understanding to what the methods are. This knowledge is quite important because, with forecasting, companies can predict what will happen in the future. Until finally the company can grow. It is very different from planning.
