Abstract: A plurality of display files representing aircraft maintenance processes are generated and linked in a hierarchy. A general level display file defines a number of divisions of aircraft maintenance processes that can include managerial as well as labor related divisions. Linked display files appearing below the general level file in the hierarchy refine the general level divisions until a basic level diagram is reached where the tasks required to perform the aircraft maintenance processes are defined and the input elements for the respective tasks are shown along with output elements. The display files are linked so that selecting items on a diagram causes corresponding lower level diagrams to be displayed. The linked display files representing the aircraft maintenance processes provide graphical information regarding dependencies and relationships between processes that can be used in selectively implementing aircraft maintenance applications across segments of an aircraft maintenance operation.
