The solution is stable. 

I give the stability a nine out of ten.

I have been seeing some glitches for a while, like in the last two, three versions, where the UI on the developer's tool takes lots of memory, and then the screen gets frozen. Then there are multiple artifacts that are open and if we try to toggle in between, that becomes really painful because you'll have to restart which takes time. This happens multiple times.

Blaze Advisor does have maintenance. They provide a one-year license with the version and every year it needs to be renewed. Once you renew the license, then those licenses need to be updated against all the services. That is one thing, then if there is a version change, definitely there would be upgrades and those things which come with it.

We haven't had any stability issues in the time I've been using the product. We may have had one small issue with an update early on but no problems otherwise.

FICO Blaze Advisor is stable.

Impression to the development tools:

There are issues using it. For example, now we are solving for big strategies that we need for development. Just loading the strategy to the Blaze IDE takes 20 seconds or more. Only then you can start working in IDE. Only opening one of the Decisioning projects takes 1-5GB of RAM.

IDE is sometimes unstable especially if are corrupted objects or versioning system data.

But the opposite is the Decisioning engine which is stable, with almost no issues with it.

This is a stable product.

Blaze Advisor is very stable. It is one of the best tools, one of the best rules engines in its category.
