Software sustainability has been identified as one of the key challenges in the development of scientific and engineering software as we move towards new paradigms of research and computing infrastructures. However, it is suggested that sustainability is not well understood within the software engineering community, which can led to ineffective and inefficient efforts to address the concept or result in its complete omission from the software system. This paper proposes a definition of software sustainability and considers how it can be measured empirically in the design and engineering process of software systems.
