How does a workflow engine work?
A workflow engine is a software application designed to help users enforce a series of recurring tasks that make up a ‘business process’ or a ‘workflow’. Workflow engine takes cues from the workflow’s design and guides the process through its various steps. This is done by task routing, also called workflow automation.
How do I choose a rule engine?
When choosing, it’s good practice to look at how powerful the rules engine is (its depth of functionality), how easy it is to use (its level of complexity) and how ready it is to support your future needs (based on your growth trajectory and features you may need).
When should you not use a workflow engine?
No matter how many steps or rules or logic are between those two points the result is the same. So, if you have processes that are variable from start to end, use a workflow. If the same process can be used by everyone, then you don’t need a workflow.

How does Drools / Red Hat JBoss BRMs improve collaboration?
Drools/Red Hat JBoss BRMS has no built-in collaboration.
