Evaluating the Quality of Proposed Agile XScrum Model

The software companies are practicing XP and Scrum models from last several years. XP lacks in management practices whereas Scrum is weak in engineering practices. Due to continually promising need of agile development, this research tackles the problems of XP and Scrum by integrating them to enrich the strengths of XP and Scrum and suppress their limitations. The previous attempts provide little effective empirical evidence regarding the integration of XP and Scrum. Therefore, there is a pressing need to provide empirical evidence for the integration of XP and Scrum to show its usefulness developing the software projects. The same is accomplished by proposing XScrum model. Another goal of this paper is to analyze the quality of proposed XScrum with existing XP and Scrum. The proposed XScrum is validated by performing three case studies for three industrial projects and the results are described in the paper. The results are presented using quantitative and qualitative data. The results provide empirical evidence that there is a significant improvement in quality of proposed XScrum as compared to the existing XP and Scrum.
