We have used another statistical tool for years as part of our Lean Six Sigma deployment. Due to a recent significant increase in that company's cost structure we began looking for another alternative. A friend recommended QI Macros and we went ahead and purchased and have been very pleased. We really like that its so integrated with Excel. Now many of our project workpapers can be located all in one Excel workbook which is awesome. Using our prior system we were constantly going back and forth between Excel and the other statistical software (lots of motion waste) in order to do things like control charts, pareto charts, histograms, and statistical tests, now its all in one place. We really like the wizards and the templates for things like fishbone diagrams, cause and effect matrices, etc... We enjoy the help videos that are easily accessible and I have been super impressed with the help function, as the team from QI Macros is so responsive to any questions you have. Wish we had made the switch long ago. Thanks for making a great product.
