Qualitative Forecasting Techniques

Qualitative Forecasting Methods in Business Management

Qualitative forecasting methods are used to predict future events based on expert opinion, judgment, and intuition rather than historical data. These methods are often useful when there is little or no past data available, or when a business wants to capture human insights on future trends.

1. Sales Force Composite

  • Definition: The Sales Force Composite is a forecasting method where salespeople provide their estimates of future sales. The individual forecasts from each salesperson are combined (or averaged) to form an overall forecast for the company.
  • Process:
    • Salespeople Submit Forecasts: Each salesperson estimates future sales in their respective regions or for specific products, based on customer interactions, market trends, and their knowledge of the field.
    • Managerial Review: Sales managers or supervisors review the individual forecasts. They might adjust the forecasts based on macroeconomic trends, historical data, or company goals.
    • Aggregation: Once all adjustments are made, the individual forecasts are combined to form the overall company sales forecast

Example

A company selling consumer electronics might ask its sales staff in different regions to provide estimates for next quarter's sales based on recent customer orders and interactions. A salesperson in the northeastern region estimates a 15% increase in tablet sales, while another in the southern region estimates a 10% decrease in laptop sales. These individual forecasts are then reviewed by the sales manager, adjusted for any broader company goals or market trends, and compiled to create an overall forecast for the quarter.

Best Used When:

  • The company wants to incorporate firsthand customer insights into the forecast.
  • There is a need for specific, localized, or product-specific forecasts.
  • The business operates in a rapidly changing market where sales teams have up-to-date information.

The Sales Force Composite is highly useful for organizations that rely on close customer interactions and want to utilize their sales team's market knowledge in forecasting.

  • Advantages:
    • Salespeople have firsthand knowledge of customer needs and preferences.
    • It allows for the incorporation of real-time market insights.
    • Forecasts can be easily broken down by region, product line, or customer segment.
  • Disadvantages:
    • Salespeople may overestimate or underestimate sales due to bias or motivation.
    • The accuracy of the forecast depends heavily on the experience and judgment of salespeople.
    • There may be inconsistency in forecasting approaches among salespeople.

 

2. Delphi Method

  • Definition: The Delphi Method is a structured forecasting process that gathers input from a panel of experts over several rounds of questioning. It is designed to achieve a consensus forecast without face-to-face meetings.
  • Process:
    • Selection of Experts: A panel of experts is chosen based on their knowledge, expertise, and experience in the area of interest. These experts often come from different industries or disciplines to provide diverse perspectives.
    • First Round of Questionnaires: Each expert is sent a questionnaire or survey asking for their forecast or opinion on a specific topic (e.g., market trends, technological advancements, economic changes).

    • Compilation of Responses: The responses from the first round are collected, summarized, and then shared anonymously with the panel. This allows experts to see the range of opinions without knowing who provided each response.

    • Second Round of Questionnaires: Based on the feedback and summary, experts are asked to review their initial responses. They can either stick to their original forecast or revise it in light of the other opinions. This process is repeated for multiple rounds.

    • Consensus or Stability Reached: The rounds continue until the group reaches a consensus or the responses stabilize (i.e., no significant changes in opinions occur). The final forecast is derived from this agreed-upon consensus.

  • Advantages:
    • Provides expert insight and avoids groupthink, as experts do not directly influence each other.
    • It allows the use of anonymous input, encouraging honesty and reducing bias.
    • Useful for long-range forecasting or in complex scenarios with little historical data.
  • Disadvantages:
    • Time-consuming due to multiple rounds of questionnaires.
    • The quality of the forecast depends on the selection of the right experts.
    • It can be expensive to coordinate, especially with a large panel.

Example

A technology firm is trying to predict the future adoption rate of a new artificial intelligence (AI) technology. A panel of AI experts, industry leaders, and futurists is assembled. In the first round, each expert provides their forecast on how quickly the technology will be adopted in various industries. After receiving anonymous feedback from the panel, each expert revises their estimate in subsequent rounds until the panel reaches a consensus prediction on when the AI technology will become mainstream.

Best Used When:

  • There is high uncertainty about future outcomes (e.g., new technologies, market disruptions).
  • Historical data is unavailable or unreliable for making quantitative predictions.
  • You need expert opinions from various fields or industries.

The Delphi Method is especially valuable in long-term forecasting or when dealing with complex, rapidly evolving situations where the knowledge and judgment of experts are critical to making accurate predictions.

 

3. Consumer Survey

  • Definition: Consumer Surveys involve directly asking customers or potential customers about their future buying intentions. The forecast is then based on the responses received from the survey.
  • Process:
    • Designing the Survey: The business designs a questionnaire that targets key information such as:

      • Future purchasing plans (e.g., when and how much they intend to buy).
      • Preferences for product features, pricing, and services.
      • Opinions about market trends or new products.
    • Selecting the Sample: The company determines the sample of consumers to survey. The sample should be representative of the business’s target market to ensure accurate results. Factors such as age, gender, income, and geographical location are considered.

    • Conducting the Survey: The survey is conducted using various methods, such as:

      • Online surveys (via email or social media platforms).
      • Telephone interviews.
      • Face-to-face surveys in retail stores or public spaces.
    • Analyzing Responses: Once the survey is completed, the responses are analyzed to estimate future demand, customer preferences, and any patterns in consumer behavior. This information is used to forecast sales or inform product development.

    • Adjustments: The data collected may be adjusted to account for factors such as biases, sample size, or external influences like economic conditions or seasonal demand

 

  • Advantages:
    • Provides direct insight into customer preferences and future purchasing behavior.
    • Useful for forecasting demand for new products or for making adjustments to existing products.
    • Can help identify trends or changes in consumer behavior.
  • Disadvantages:
    • Consumers may not accurately predict their future buying behavior.
    • Surveys can be costly and time-consuming to conduct.
    • The results may be biased if the survey sample is not representative of the entire market.

Example

A company planning to launch a new line of eco-friendly packaging for their products conducts an online consumer survey to gauge potential interest. The survey asks questions about consumers’ willingness to pay a premium for eco-friendly options, how frequently they purchase similar products, and what features they value most in sustainable packaging. Based on the survey responses, the company can forecast demand for the new product line and make decisions about pricing and marketing strategies.

Best Used When:

  • You are introducing new products or services and need to understand consumer demand.
  • You want to gauge changing consumer preferences or market trends.
  • Historical data is insufficient or irrelevant for predicting future demand.

A Consumer Survey is a powerful tool for gathering direct input from consumers about their intentions, preferences, and behavior, allowing businesses to make informed decisions about future sales and product development. However, its accuracy depends on careful design, a representative sample, and thorough analysis of the data collected.

4. Jury of Experts (or Jury of Executive Opinion)

  • Definition: The Jury of Experts method involves gathering a small group of executives or experts within the company to provide their forecasts based on their experience and knowledge. These forecasts are then discussed and combined to reach a consensus.
  • Process:
    • Selection of Experts: A panel of experts or executives from different departments or fields (e.g., sales, marketing, finance, production) is assembled. These individuals are selected based on their knowledge, experience, and understanding of the market or industry.

    • Individual Forecasts: Each expert provides their individual opinion or forecast based on their experience, insights, and any available information (market trends, internal data, etc.). This forecast could cover sales, market demand, product performance, or any other future business outcomes.

    • Group Discussion: The experts meet and discuss their forecasts. They share their reasoning, debate differing opinions, and consider various internal and external factors. This exchange of ideas helps in refining the forecasts.

    • Consensus Forecast: After discussion, the group agrees on a collective forecast that represents the consensus of all participants. If full consensus cannot be reached, the experts may settle on an average or compromise forecast.

    • Review and Adjustment: If necessary, the forecasts may be revisited and adjusted over time, especially in response to new market conditions, company strategies, or emerging trends.

 

  • Advantages:
    • Provides a quick and relatively inexpensive method of forecasting.
    • Allows for the use of expert judgment and experience from multiple departments.
    • Encourages collaboration and discussion within the organization.
  • Disadvantages:
    • Can be influenced by dominant personalities, leading to biased results.
    • The quality of the forecast depends heavily on the expertise of the participants.
    • Lack of structured analysis or data can make the forecast subjective.

 

Example

A retail company is preparing to launch a new product line and needs to forecast sales for the first year. The company assembles a group of executives from sales, marketing, and finance to form a Jury of Experts. Each executive gives their estimate based on their area of expertise: the sales manager draws on current market trends, the marketing director considers consumer preferences, and the finance officer factors in economic conditions. After discussing their predictions, the group arrives at a consensus forecast for the new product launch.

Best Used When:

  • The business needs a quick forecast based on expert judgment, particularly when time or resources are limited.
  • There is a lack of reliable historical data or quantitative models.
  • Multiple perspectives from different departments or areas of expertise are needed to form a comprehensive outlook.

The Jury of Experts method is especially useful for short-term decision-making, new product launches, or when qualitative insight is more valuable than statistical data. It leverages the experience of key individuals but should be complemented with other forecasting methods for more accurate predictions, especially in complex situations.
