The ability to schedule and maintain a mainframe environment. It's easy to use and allows you to have control over every aspect of your mainframe. I dislike how it sometimes takes the user too long to load their own programs into the system. Sometimes it can take up to 10 minutes just to load one program. If you are looking for a mainframe scheduling solution that will allow you to manage all aspects of your mainframe, this is it. We are using it to schedule our maintenance jobs, as well as to automate certain tasks.
