SURVEY DATA & DIRECTORY To view the survey results as well as a directory of vendors who participated in the survey, click here. If you use data to make forecasts, what should you look for in a vendor and the product? First, find out the capabilities of the software. Specifically, what forecasting methodologies can the product do? Does it find the optimal parameters of the procedure for your particular data set or must you manually enter those values? How extensive, useful and clear is the output? Most, but not all, vendors allow you to download a time-trial version of the software that typically expires in anywhere from a week to a month. Ideally, the trial version should allow you to work with your own data and not just “canned” data that the vendor bundles with the trial software. Verify if the trial version has size A NA L Y T I C S limitations of the data, and if so, are they overly restrictive. Ask about technical support, updating to a newer version when it is released and differences (if any) depending on the operating system you are using. Contact the vendor with your specific questions. Users tell me, and I have independently found, that most vendors have good and helpful technical support before and after you buy.
