Did the North Carolina Department of Motor Vehicles regain its sanity? Or was this just another tease? As you recall from last year, my application for “THE BFD” personalized license plate was accepted – then rejected – even though that extra $30 fee could have eased at least some of

Self-anointed as The Aristocrat of forecasting related blogs, The BFD takes its public service role seriously (or at least as seriously as anyone who self-anoints on a regular basis can be taken). Among the services The BFD provides, both publicly (on webcasts or speaking engagements) and privately (by phone, email,

This week I received an urgent text message from a good friend and former colleague in the consulting business: Mike, I am down 24 pages in your book and [besmirching my trousers]. Is there no hope for consultants like me? My response was to not let the book ruin a

The Winter 2009 issue of Foresight had an article by Kesten Green and Len Tashman, reporting on a survey (of the International Institute of Forecasters discussion

The Summer 2010 issue of Foresight is now available. Here is Editor Len Tashman’s preview: For so many years, we forecasters have developed and refined models for demand forecasts – forecasts for product and item sales, orders, shipments – without paying adequate attention to the details of how these forecasts

Better forecasting can, of course, help address many business problems. We want to believe that more accurate forecasts are always possible. “If only,” management bemoans, “if only we had bigger computers, more sophisticated software, more skilled forecast analysts – or if the analysts we have just worked harder!” Unfortunately, there

Just as we all eagerly awaited announcement of the $1 million prize winner of the Pillsbury Bake-Off(R), every forecasting software vendor has endured the "bake-off" hosted by organizations in the market for new forecasting software. Software selection teams utilize a bake-off to help evaluate competing vendors. Vendors are given a

The F2010 Business Forecasting Conference wrapped up on June 8. Chaired by Tim Rey of Dow Chemical and Jerry Oglesby of SAS, this was another strong event, bringing together 248 forecasters from business, government, and academics, representing 27 states and 11 countries.

Was it the economy? the timing? the location? or the brilliant and good looking Forum panel? That will be for history (or you) to decide. What we do know is that is that the Institute of Business Forecasting’s Best Practices Conference in San Francisco, April 28-30, drew a large and

My friend Tom Reilly of Automatic Forecasting Systems posted this comment on the INFORMS discussion group on LinkedIn: Some use all of the data and some withhold data to find the best forecasting model?

The Spring 2010 issue of Foresight is now available. Here is Editor Len Tashman’s preview: What’s the connection between hindsight and foresight? That is the question Paul Goodwin asks in his Hot New Research column leading off this issue. The problem is that hindsight bias – the tendency to believe

Although you probably didn’t notice, I stepped away from this blog for the last two months to think about something more important: The current state of business forecasting. I’d come to realize there is a lot of animosity in the world of forecasting. We have advocates of statistics, and advocates
