It is easy to use for all levels including beginners. The interface makes it very user friendly while still being robust enough that even advanced users can understand it without much trouble. I like how quickly you can create models in this software. You don't need a lot of training time nor do you have to be an expert at using Excel before you learn how to work with Enterprise Optimizer. Sometimes there is lag between when information gets into the system and when we see any updates but other than that it's been pretty great! We were looking for something simple so people who aren't super technical could easily set up their own optimization process within our organization. This product has helped us automate many processes which previously required manual intervention.
