A system and method for enhanced diagnostic fault detection and isolation is provided, wherein COTS/MOTS subsystems of a system under test are evaluated in a hierarchical manner providing improved test coverage and a reduction in ambiguity group size. The enhanced diagnostic fault detection and isolation method may proceed from automatic built-in-test to initiated built-in-test and finally to manual tests. At each stage of the testing, results may be evaluated to determine which, if any, components need replacing. The diagnostic system may report the results of testing in a fault log and/or a look-up table structure. The systems and methods of the present invention are suited to testing systems that incorporate COTS or MOTS subsystem components, and for use with an interactive electronic technical manual (IETM). Further, the diagnostic system is adaptable to a variety of subsystem interface protocols.

Enhanced diagnostic fault detection and isolation

A graphical mark-up language authoring system using drag and drop placement of symbols representing mark-up language elements on a computer screen drawing and connecting the blocks by lines representing data and control flow to create a mark-up language sequence design. The symbols are instances of a mark-up language element that include the properties and attributes of that element. The system also includes a mark-up language view of the elements and their attributes and properties. The system permits effective authoring of mark-up language sequences by users not expert in mark-up language sequence design.
