Is My Software "Good Enough" to Release? - A Probabilistic Assessment

We present the basics of a probabilistic methodology to assess the overall quality of software preparatory to its release through the evaluation of process and product evidence, the " \´good enough\´ to release" (GETR) methodology, in this paper. GETR methodology has three main elements: a model whose elements represent activities and artifacts identified in the literature as being effective assessors of software quality, a process for populating certain parts of the model, and methods for analyzing the importance of contributions made by individual evidence to the determination of overall system quality. First, the methodology\´s components are briefly introduced. A demonstration of how the methodology can be applied is then given through two case studies reviewing release assessments for in-house developed analytical tools. The robustness of the model is also illustrated by the results of the case studies
