A Systematic Study to Improve the Requirements Engineering Process in the Domain of Global Software Development

Abstract

The software organizations are outsourcing their development activities across the geographical border due to huge business gains. However, the adoption of the global software development (GSD) paradigm is not straightforward; various challenges are associated with it, particularly related to the requirements engineering (RE) process. The objective of this study is to identify the barriers to the RE process faced during GSD. To achieve this, we have conducted a systematic mapping study and questionnaire survey to identify and validate the barriers of the RE process with industry practitioners. A total of 20 barriers were identified and validated with the experts. Moreover, we have performed organization types (client and vendor), organization size (small, medium, and large) and experts' levels (junior, intermediate, and senior) based analysis to provide a clear understanding of the RE barriers in the three different context. Besides, we have also developed a theoretical framework by mapping the investigated barriers into six core knowledge areas of software process improvement. The mapping results indicated that project administration is the most significant knowledge area of investigated barriers. We believe that the findings of this study will provide a framework that assists the GSD practitioners in developing an effective plan and strategies to improve the RE process in the GSD context.

Identifying the administrative challenges encountered by the principals in low-performing public secondary schools of Faisalabad District, Pakistan

“…This categorization seems to create invalidity in the study. But these threats were removed when we realize that many researchers adopted the same way to classify the explored challenges (Akbar et al, 2020;Chen et al, 2011;Hallinger, 2014;Yusuf, Gunasekaran, & Dan, 2007).…”

“…For this purpose, the Chi-Square test (Linear-by-Linear Association) was implied to find the significant distinction among the challenges concerning the school types. Previously, many other researchers adopted the same categorization approach (Akbar et al, 2020;Akbar, Shafiq, et al, 2019;Shafiq et al, 2020). Thus, the hypotheses addressed below were formed to analyze the significant variances among the identified challenges:…”

Survey on vehicle map matching techniques

“…The research method of software engineering is very popular, which needs to establish the review goal and research method, and then draws a conclusion [22][23][24]. In [25], researchers believed that a systematic framework can effectively assign effective plans and strategies to assist practitioners. Ghazi et al [26] reported that the demand for empirical research on software engineering is growing, and by following the research methods of software engineering to determine the problems researchers face in the investigation design and mitigation strategies.…”

Quality Evaluation of Structural Design in Software Reverse Engineering: A Focus On Cohesion

“…Ontology has been applied to various domains (including artificial intelligence, medical engineering, library science, and software engineering) because ontology can help to formalize a conceptual model of a specific domain to establish and share explicit and implicit knowledge in this field between people and machines [43], [44]. Software engineering and development is a complex and knowledgeintensive process, and research on applying ontology to software engineering domain has drawn much attention for effectively sharing domain-related knowledge in the collaborative development of software [45]. Numerous software engineering ontologies have been developed.…”
