Systematic literature review and empirical investigation of motivators for requirements change management process in global software development

Most software development firms have adopted the concepts of global software development (GSD) to develop high-quality and low-cost products. However, GSD is not a straightforward process. It is associated with many challenges that are mostly related to requirements change management (RCM). In this study, we explore the motivators that contribute to managing RCM activities in the GSD environment. We extracted a total of 25 motivators using the systematic literature review (SLR) approach and conducted a survey study to empirically evaluate the findings of the SLR. The results of the applied Spearman's statistical test show that the findings of the SLR and survey study had a positive moderate correlation (r(s)(25) = 0.566). We further analyzed the reported motivators according to organization size. Finally, we developed taxonomies of the identified motivators based on the framework proposed by Ramasubbu and the project management body of knowledge. We believe that the taxonomies provide a robust framework for tackling the challenges of RCM, which is significant for the success and evolution of GSD firms.
