It is like any tool. It has bugs. We fly through some of the bugs.

Without being repetitive, I consider the solution to be rather stable.  Just the cross over between model perspectives can cause some hiccups.  

I would rate the stability a ten out of ten. It's rock-solid. We haven't encountered any issues in recent times.

Magic MagicDraw is a stable solution. We didn't have any issues during our tests.

I rate the stability of No Magic MagicDraw a seven out of ten.

Due to the fact that the tool loads models completely in main memory (no lazy loading) large models in combination with low JAVA memory settings can lead to crashes. Someone in the team should be able to cut models into modules.

It is very stable. They also update the software and when they do, they send an email to let us know what has changed and what new features we can use.

This solution is stable. I have not experienced any glitches and nothing has crashed that I haven't been the cause of.

The solution is stable. 

It's a stable solution. We have not had any issues.

Stability and scalability are both good. Our clients are mainly enterprise size.
