AÇIK KAYNAK YAZILIMLARDA BAKIM YAPILABİLİRLİĞİ VE GÜVENİLİRLİĞİ ÖLÇMEK İÇİN İKİ BOYUTLU DEĞERLENDİRME METODU

Abstract

Increased popularity of open source software (OSS) has led to a considerable proliferation of alternative software. However, this being the case, an evident lack of studies that would contribute to evaluation of OSS by organizations has turned the process of selecting the most suitable product into an appealing research problem. In this study, a method to evaluate reliability and maintainability of OSS products by using both code-based and community-based aspects have been obtained from the synthesis of existing studies in the literature and with our contribution. In order to perform code-based evaluation, some internal attributes of the most recently quality model, ISO/IEC 25010, have been selected and object-oriented C&K metrics have been employed in an attempt to measure these attributes. To perform community-based evaluation, metrics derived from historical data such as e-mailing lists, program reports, frequently asked questions, and etc. have been utilized to identify and satisfy information needs as conformant to ISO/IEC 15939 standard for software measurement process. The proposed method has been used to evaluate the maintainability and reliability of three Java program build tools written in Java, and results of evaluation have been presented and discussed.
