John Galt believes that success of every plan lies in the accuracy of the baseline forecast. John Galt has compiled a list of busness and sales forecasting techniques that addresses many of the business issues facing our customers today. In 1998, we entered our algorithms in the M3 competition, an academic competition for statistical accuracy, and ranked #1 and #2 in most categories.

Our sales forecasting software and statistics have been integrated into Peoplesoft’s Supply Chain Solutions and GEAC’s Comshare budgeting software packages. Our symbol stands for quality and reliability. If you are interested in integrating foresting algorithms into your home grown application or commercial forecasting software, read more about the ForecastX SDK. The business and sales forecasting software includes more than 20 forecasting techniques and more than 40 statistical forecasting methods.
