To whom it may concern:
I have used many statistical packages before, but I must say that Strategy is the easiest to learn. The output is clear and the notes that accompany the plots help you interpret your data. Most importantly, Strategy has a GridSearch capability to find the combination of factors that optimizes your process. I know of no other software that offers this. GridSearch alone makes Strategy a good investment.
Working with Al Corwin of Process Builder has been a pleasure. Everyone at Process Builder works very hard to help you with your problems and answer your questions. They are always there when you need them. Their turn around time is very fast. I couldn't ask for much more.
