A Customized Quality Model To Evaluate Domain Engineering In Software Product Line

Abstract

software product line is a set of software-intensive systems that share a common, managed set of features satisfying the specific needs of a particular market segment or mission and that are developed from a common set of core assets in a prescribed way , its recognized as a successful approach to reuse in software development . Software quality models have been widely used for assessing software quality during system development .howevertheir use for evaluating the outputs of software product line phases,such as the domain engineering outputs (Family Architecture and the core assets implementation ) has been extensively not reported. This research proposes a quality model to evaluate the variability of the common parts (domain engineering outputs) which are very importance for each product in the family. Moreover, the research evaluates the previous research in software product line carefully to identify a proper way to develop the proposed model. The proposed model is customized from (ISO/IEC 9126-1) model, in addition to some related concepts extracted from the key features of software product line development approach. Furthermore, the model will evaluate the core assets at early development phases in order to accurate prediction of final system quality, hence producing products in an effective way( lower cost and shorter time). The variability of core assets and product line architecture is evaluated based on the functionality, reliability, usability and efficiency measurements .each attribute has its weight in the whole variability value. The proposed model applied for the core assets and general structure of the administrative package of Sudan university of science and technology and the result of evaluation s that the variability of employees and user modules(which are the common modules in the package ) is 77.89% .
