Predecessor work introduced the "'Good Enough' to Release" (GETR ) Methodology, a process by which engineering judgment as to the acceptability and importance of disparate evidence is transformed into a system-level assessment as to the overall acceptability of a computer-based system for release to a user community. In this paper, we discuss the adaptation of the base GETR model, shown in Figure 1, for use in the assessment of performance quality of computer-based systems. Sources of appropriate quantitative and qualitative evidence are identified through a review of relevant literature and categorized as sources of either process or product evidence. The two main model branches are accordingly populated. The paper ends with a discussion of future work, including the validation of the new model, whose working name is "'Good Enough' Performance" (GEP), and suitable case studies.
