Editor-in-Chief Len Tashman's Preview

The forecasting field is surely cross-disciplinary, as exemplified by the diverse membership of the International Institute of Forecasters (the publisher of this journal), but it is also multidimensional, as can be clearly seen in this Summer 2017 issue. The articles you’ll read here encompass sales and operations planning, long-range forecasting, forecasting methods and accuracy measurement, and the intricacies of communicating forecasts to decision makers. Previous issues of Foresight have reported on financial forecasting, supply-chain forecasting, forecasting support systems, strategic forecasting, forecast process improvement, prediction markets, and many other areas.

One of the most influential books on S&OP came out in 2006 from Chris Gray and John Dougherty, Sales and Operations Planning – Best Practices. Now Chris and John reflect on their long experience in forecasting, planning, and manufacturing to describe Misconceptions, Missteps, and Bad Practices in S&OP. As you’ll see, their list of problematic matters is long, and the current presentation is just the first installment of what will be a multipart article.

Our latest forecasting-methods tutorial, from Fotios Petropoulos and Konstantinos Nikolopoulos, is on The Theta Method, a relatively simple time-series method that has achieved a notable track record for accuracy but has been overlooked in commercial software. The tutorial shows how the method can be implemented in the R program.

Longevity risk is the burgeoning threat that people will actually outlive their financial assets, what with our spectacular increases in longevity and the aged-dependency ratio. This is especially true as traditional pension plans are being replaced and public retirement funds are facing insolvency. Ira Sohn frames the problem in his compelling article Longevity: Blessing or Curse? The bottom line is that today’s sociopolitical policies are not even close to being adequate to deal with the threats we’re facing.

One of the greatest challenges forecasters in all fields face—and do so over and over again—is that of Communicating Forecasts to the C-Suite. Todd Tomalak offers here A Six-step Survival Guide. We would welcome readers’ perspectives on and additions to this list, so please send us your thoughts.

Our final article deals with The Quest for a Better Forecast Error Metric: Measuring More than the Average Error. Here, Stefan de Kok makes a strong argument for the need, particularly in supply-chain management, of probabilistic forecasts and metrics to assess their accuracy. Standard accuracy metrics (MAPEs, RMSEs, and the like) don’t reveal the critical information we need to properly gauge risks and set safety stocks.
