Implement a businessRuleTask BPMN 2.0 construct by integrating Drools expert. In this first version the Drools rules can be deployed to the Activiti Engine just as you would deploy a process definition. The Drools expert engine will run inside the Activiti Engine to execute the rules. In the near future we want to add a web application where you can edit and probably also test rules. We'll try to make this web application non-technical.
