[rules-dev] Drools usage

I'm not sure that this is the right place to ask this but I try anyway. For one of our project we want to use JBoss Drools. Although we are convinced (technical people) that this is the right choice for the project, our management wants to be reassure and they'd like to have some examples of successful project using Drools in different clients. Do you have such examples? Cheers Antony
