Managing Forecasting methods

One of the most necessary steps of the Demand Forecasting progress the selection of the appropriate program for Demand Forecasting. Demand can forecast using Qualitative methods or Quantitative methods as explained below:

Qualitative methods:

  • The Delphi Technique: A panel of professionals appointed to outcome a Demand Forecast. Each professional asked to generate a forecast of their assigned necessary segment. So, after the initial forecasting round, each professional reads out their season and in the process, each expert influenced by other experts. A consequent forecast is again made by all experts and the process is repeated until all experts reach a near consensus scenario.
  • Sales Force Opinion: The Sales Manager asks for results of expected demand from each Salesperson in their team. Each Salesperson calculates their various region and product categories and provides their single customer demand. Finally, the Sales Manager aggregates all the demands and generates the final version of Demand Forecast after the administration’s judgment.
  • Market Research: In market research method, customer-specific surveys deployed to generate potential demand. Such surveys generally in the form of application that directly seeks personal, demographic, preference and economic advice from end customers. Since this type of research on a random sampling basis, care needs to be exercised in terms of the survey regions, locations, and demographics of the end customer. This type of techniques could profitable for products that have some no demand history.

Quantitative methods:

  • Trend projection method: Trend projection technique completely deploy businesses with a large buying data history of typically more than 18 to 24 months. This historical data generates a “time series” which noted the past sales and headed demand for a specific product. The category under normal conditions by a graphical plotting method or the least square method.
  • Barometric technique: Barometric technique of Demand Forecasting is depend on the principle of recording events in the present to pretend the future. In the Demand Forecasting process, this completed by analyzing the statistical and economic indicators. Generally, forecasters deploy analytical analysis like Leading series, Concurrent series or Lagging series to produce the Demand Forecast.
  • Econometric forecasting technique: Econometric forecasting produce autoregressive integrated moving-average and complex mathematical equations, to establish relationships between demand and factors that leverage the demand. An equation copied and fine-tuned to ensure a reliable historical representation. Finally, the projected data of the influencing variables are inserted into the question to generate a forecast.
