The tool is stable. I rate the stability an eight out of ten.

Stability-wise, I rate the solution a nine out of ten. Regarding stability, since the product is from Microsoft, there is something that you will always need from other parties, especially third parties.

The solution is stable and I would rate its stability a nine out of ten. 

I rate the stability an eight out of ten.

I rate the product's stability an eight out of ten. 

The solution is pretty stable. I used it on an earlier job and it was fine. There were no bugs or glitches. It doesn't seem to crash or freeze. It's good overall. 

The solution is very stable.

It crashed many times, because in engineering there are a lot of phases.

For example, the first phase will be preparing the document specifications about the product while the second phase is preparing the design, at the same time the third phase is preparing the prototype and the fourth is doing the product implementation.

I am not familiar with any issues with respect to stability, and I have never seen Team System crash.

I did have some issues with the 2015 version where on very few occasions it froze or just crashed. With the 2017 version, I have never had this problem. I have to say that with the 2017 version, the stability has improved.
