Software dependability in the operational phase

Software quality should be built-in and maintained throughout the software life cycle, which requires understanding of software dependability in actual environments. This thesis discusses how to develop analysis techniques for evaluating the dependability of operational software using real measurements while taking design issues into account. The issues addressed include fault categorization and characterization of error propagation, symptom-based diagnosis of recurrent software failures, identification of software fault tolerance, evaluation of the impact of software faults on the overall system, and the development of techniques for analyzing multiway failure dependencies among software and hardware modules. The process is illustrated using a case study of the Tandem GUARDIAN operating system.
