I'm learning jBPM but I'm interested in drools as well. This question got me thinking: Why would you want to modify a workflow definition at runtime?

The out-of-office rule seems overkill to me. Why not assign a given task to a group of users, so that anyone could "pick" this task up and execute, instead of going through hoops to check if one given user is in the office or not?

Maybe a better approach would be to define a bigger, more robust workflow?
