N2 - As a measure of system reliability, the mean time to failure falls short on many fronts: it ignores the variance in stakes among stakeholders; it fails to recognize the structure of complex specifications as the aggregate of overlapping requirements; it fails to recognize that different components of the specification carry different stakes, even for the same stakeholder; it fails to recognize that V& V actions have different impacts with respect to the different components of the specification. Similar metrics of security, such as MTTD (Mean Time to Detection) and MTTE (Mean Time to Exploitation) suffer from the same shortcomings. In this paper we advocate a measure of dependability that acknowledges the aggregate structure of complex system specifications, and takes into account variations by stakeholder, by specification components, and by V& V impact.
