  • Six Steps to Overcome Bias in the Forecast Process by Elaine Deschamps
    Aristotle wrote that “Man is by nature a political animal,” and human nature in the world of forecasting is no different from human nature in any other political environment. By addressing the organizational politics of forecasting, we are seeking to identify and ultimately overcome bias in the forecast process.
  • The Impact of Corporate Culture on Sales Forecasting by John Mello
    Based on forecasting audits conducted in six companies and interviews with the corporate forecasters, John Mello distinguishes between the corporate values and strategies that benefit the salesforecasting process and those that undermine it. We may recognize our own organizations in his study and realize that we are on the right or wrong track.

Articles

      1. Managerial Judgment: Best as an Input to the Statistical Forecasting Process by Rob Dhuyvetter
        Rob Dhuyvetter shares his ideas and experience at the J.R. Simplot Company on the combining of statistical and judgmental forecasts. His main recommendation: rather than limit the use of managerial judgment to the adjustment of the outputs of statistical forecasting models, bring managerial judgment directly into the development of the statistical forecasting model. A key in doing this is timely communication with sales and marketing, and full documentation by sales and marketing of those assumptions they present to the forecasters and planners.
      2. My Life as Soothsayer: 25 Years of Forecasting at British Telecom by Clive Mason
        Clive Mason reflects on the changes that have taken place during his time as a forecasting practitioner at British Telecommunications PLC (BT) and its predecessors, back to and including the Post Office. He does not intend this paper to be a definitive study of forecasting methods in the telecommunications market. Rather, he focuses on the changes in the operating environment of BT over the last 25 years, considers the implications of these changes for forecasting practitioners, and examines the responses to challenges faced. He also discusses the evolution of the forecasting tool kit from simple graphical projection to automated systems.
      3. To Include or Not To Include an Explanatory Variable: That is the Question by William M. Bassin
        The addition of an explanatory variable to a regression model can increase its historical explanatory power but decrease forecast accuracy. The difficult decision is whether or not to use this explanatory variable in forecasting. The author shows how to decide on inclusion or exclusion.
