I love how easy everything is for our users in order process changeovers or even when we need some support with one specific function! The best part about Revo so far was that everyone working together could figure out what needs fixing before any code changes were made which meant less training/teaching required from us at all (which means more work done).
We didn't realize until after implementation but there are many things going wrong during testing etc where you can find yourself stuck if not already familiarized wtih other tools like this. You would think by now people have figured something else similar comes along eventually - however since every software developer knows their stuff these days they probably do know such an amazing tool exists somewhere out ther ebut havent found them yet? A lot better than Excel though as well!! There's nothing currently missing although i understand its only been around two years. Its hard because no matter who uses it most.
