I have used multiple decision rule engines, but this particular client, where I'm working right now, was using the Blade Advisor from day one. There was no switch. But there are different things which are available on the market. I haven't seen somebody switching from one to another, in my area at least.

We did previously use another solution - SQL logic. In previous years was implemented Drools only for testing as a challenger of Blaze Advisor. It was Drools from the Red Hat company as a preinstalled cloud solution. Drools did not offer user comfort as a Blaze IDE.

Prior to working with Blaze Advisor, we were manually writing the decision management rules in Java.

I have exposure to and training on the PegaRULES engine and I have training on TIBCO BusinessEvents which is also a rules engine, and I have had a little bit of exposure to IBM ODM as well.

The biggest disadvantage of Blaze Advisor is the initial cost, but if you consider its advantages such as that it is easy to use, developed rule templates, and the most powerful feature, the RM, which is not provided by any other tool in the category. Other tools have a UI where we can edit rules, but their features are not as compatible or as powerful as the one provided by Blaze Advisor.

BE integrates easily with TIBCO back-end services but it is not easy to customize, whereas in Blaze Advisor we can easily customize as well. That type of feature is not available in other tools.
