Supporting Custom Quality Models to Analyse and Compare Open-Source Software

The analysis and comparison of open source software can be improved by means of quality models supporting the evaluation of the software systems being compared and the final decision about which of them has to be adopted. Since software quality can mean different things in different scenarios, quality models should be flexible in order to accommodate the needs of different users. Over the years several quality models have been proposed. Even though some of them are tool supported, they are not designed to be extended or customized to better accommodate the requirements of specific business contexts. In this paper, instead of having a fixed model, we propose a workflow and a tool chain to support the specification of custom quality models, which can guide the automated analysis of open source software.
