Improving Precisely Assure MIMIX is going to be a really hard one; over the years, the tech support started off kind of rough but gradually got better and better as I used it often, being on a first-name basis with many of the customer service reps because of having to call with issues that they were always able to resolve fairly quickly. I would have liked to see more reporting, maybe automation of reports, but as far as integration with other systems, I always used Precisely Assure MIMIX on an AS/400, iSeries, IBM iSeries machine, and I cannot speak to using it on any other device.
