Several points - 
1. By performing actions - you probably mean the entry point to engine will be BllCommand? StopTaskCommand for example?
If so, we need to think about the permission of the command. who can stop a for example? What is its role?
2. You mentioned task type - does this mean extending the AsyncTaskType enum? Are you going to have your own Tasks enum?
