The most valuable feature is the language used for architecture modeling. This tool is simple to use. This is a flexible tool compared to some other solutions.
What needs improvement?
The performance is slow, which is something that should be improved. Implementing business processes could be improved. I would like to see a map of all of the processes drawn automatically. You can do it now but you need to do it manually.
Which solution did I use previously and why did I switch?
Prior to this solution, we used IBM System Architect. iServer provides greater flexibility.
