Planning and management of software sustainment is impaired by a lack of consistently applied, practical measures. Without these measures, it is impossible to determine the effect of efforts to improve sustainment practices. In this paper we provide a context for evaluating sustainability and discuss a set of measures developed at the Software Engineering Institute at Carnegie Mellon University.
