It's easy to navigate and very intuitive. I have been able to easily learn how to use it in about an hour or so. The tool's interface really could stand to be more streamlined. It's difficult to get used to using all of the different icons and menus. Sometimes it is not clear which option will open up when the button is clicked. There are some great features here and we've really made the most of them. I can't think of anything I dislike yet. Maybe you need longer to get familiar with it. If this is your first time using it, you may need a little additional training to fully utilize it. I am now able to better manage our quality by tracking control charts and trending results over time.
