Good Judgment® Open
Ever wondered how good you are at forecasting? As a business forecaster, you can do the usual comparison against a naive model (and hopefully you are beating it!). You might also compare your forecast accuracy to published industry benchmarks -- although I would strongly recommend against this. (See the section below for reasons why.)
But if you're willing to test your performance in a big pond, against the big fish, in a wide variety of forecasting challenges, sign up for Good Judgment Open. Brought to you by the authors of Superforecasting, here is the description:

Why Not to Compare to Industry Benchmarks
My argument against benchmarks is based on trustworthiness of the data, consistency of measurement across benchmark participants, and most important, the relevance of comparing performance between organizations that probably have different levels of forecastability of their data. I suspect that the "best in class" forecasters do so because they have the easiest to forecast demand -- not necessarily because they have the most admirable forecasting processes.
For a thorough and definitive discussion of the topic of benchmarking, see Stephan Kolassa's article "Can We Obtain Valid Benchmarks from Published Surveys of Forecast Accuracy," originally published in Foresight (Fall 2008), and reprinted in Business Forecasting: Practical Problems and Solutions.
