A computer-implemented data processing system for managing processing of mortgage loan applications comprises task manager logic configured to generate a first list representing a first plurality of tasks to be performed in connection with a mortgage loan application. The task manager logic is also configured to generate a second list representing a second plurality of tasks to be performed in connection with the mortgage loan application. The second list is generated after work has been performed in connection with processing the first list. The task manager logic comprises reconciliation logic configured to reconcile the first and second lists so that the work performed during processing of the first list is reflected in the second list.
