An Experimental Study on Requirements Engineering for Software Product Lines

Requirements engineering (RE) activities in software product lines (SPL) are more complex, because they involve more products and stakeholders, and require attention to variabilities and commonalities. Thus, the SPL development should be supported by an appropriate REprocess for its context, which assures usability, effectiveness and efficiency in its activities. In order to analyze these issues, an experimental study was conducted to evaluate the viability of a proposal process. The results of the study showed that the use of an appropriate support tool increases the efficiency of the process. We also observed that subjects´ experience in industrial projects and RE influences the usability of the process.
