Measuring usability of requirements using social network service in product line engineering

Consideration of the quality of software requirements is a critical activity that is directly connected to the success of a software project. In the product line engineering domain, software requirements are a fundamental part of all the core assets that can be reused in other products. In order to reuse core assets in a family product, an activity that determines quality factors with respect to the software requirements is more important in this domain than in other domains. Although there are many researches on the identification of commonality and variability issues, the consideration of quality factors for satisfying the determined software requirements has not been actively studied. In this paper, we propose a systematic method that evaluates usability in terms of user opinions published on a social network service during the development of core assets in the field of domain engineering.
