Modeling question

I have multiple Departments that each have multiple Tasks associated with them.

Each Task has an Approver associated with it. However, the Approver depends on the Department.

Each Task also has a Processor associated with it. The Processor is not dependent on the Department so can have a one to one association with the Task.

I'm trying to determine the simplest method of maintaining the Department configuration with it's Tasks, the associated Approver for each Task (based on Department) and Processor for each Task. Any suggestions would be appreciated.

Thanks,

Tracy
