Systems with high dependability requirements are increasingly relying on complex on-line fault managementsystems. Such fault management systems involve a combination of multiple steps – monitoring,data analysis, planning and execution – that are typically independently developed and optimized.We argue that it is inefficient and ineffective to improve any particular fault management step withouttaking into account its interactions and dependencies with the rest of the steps. Through six real-lifeexamples, we demonstrate this inefficiency and how it results in systems that either under-perform orare over-budget. We propose a holistic approach to fault management that is aware of all relevant aspects,and explicitly considers the couplings between the different fault management steps. We believeit will produce systems that will better meet cost, performance and dependability objectives.
