“…Many further examples of such concepts have been discussed in the engineering research literature, for example resilience, sustainability, adaptiveness, recyclability, maintainability, upgradability, manufacturability, affordability, scalability, survivability, versatility, interoperability, modularity, flexibility, and agility (Boehm & Kukreja, ; Madni, ; Adam M. Ross & Rhodes, ; Watson & Griffin, ; Watson et al, ). We note that most of these attibutes are subsumed under the general rubric of ilities, but that this may be due to insuffiencient attention being paid to other kinds of systemic virtues.…”
