Requirements change management (RCM) is an important and complicated phase in the agile for the software development process. The objective of this study was to identify and analyse the factors that can positively affect the agile RCM (ARCM) process in the context of global software development (GSD). To this end, a questionnaire survey was carried out with researcher and practitioner participants working in the field of GSD. From the 56 survey respondents, a total of 20 factors that can positively influence the ARCM activities in GSD were identified. The authors also performed a client-vendor-based analysis to investigate the significance of the considered factors for different organisation types. Additionally, they compared the data collected from researchers and practitioners. The comparison results (r s (20) = 0.076) revealed that there exists a positive correlation between the rankings in each data set. The investigated factors were mapped to ten project management book of knowledge areas, and the mapping results revealed that human resource management is the most significant knowledge area amongst the investigated factors. The findings of this study provide a robust framework to assist GSD firms in implementing ARCM activities.

The economic and strategic gains motivated the majority of software firms to adopt global software development (GSD). The adoption of GSD is not straightforward. The geographical distance between the GSD teams causes the various problems for the implementation of agile software development activities, particularly, that related to requirements change management in agile (ARCM). The objective of this study is to explore the success factors of ARCM in GSD context and prioritized them based on their significance. The study comprised of two steps: (1) identify the success factors of ARCM using systematic mapping study (SMS) and validate them with industry practitioners using questionnaire survey approach; (2) prioritize the identified success factors by applying the analytical hierarchy process (AHP) approach. A total of 21 success factors that are significant for ARCM process were identified using SMS and questionnaire survey study. The results of AHP shows that allocation of resources at overseas sites, 3C's (communication, coordination and control), geographically distributed change control board (CCB), RCM process improvement expertise and continuous top management support are the highest priority success factors of ARCM process in the context of GSD. The findings assist the practitioners to address the most priority success factors in order to successfully implement the ARCM activities in the domain of GSD.INDEX TERMS Global software development (GSD), agile requirements change management (ARCM), analytical hierarchy process (AHP), success factors.

The internet of things (IOT) is a phenomenon of connected devices over the internet to ease human life. It is a system where a separate computing device embedded with sensors is connected to other devices or to the cloud through the different infrastructures of the Internet. The implication of the IOT is still challenging in a geographically distributed environment. Particularly, the main challenges are associated with data privacy and security. In this study, we investigate in the report the risks/issue related to IoT data privacy and security from the existing literature for the last two years and provide a review. We identify a total of seven issues related to IoT data privacy and security. The findings revolved that Privacy, Security, confidentiality, and integrity are the most significant issues for IoT in the current era. The findings of this study provide the researchers with a body of knowledge about the critical issues faced by the users and practitioners of IOT across the globe. Contribution/Originality: In this paper, we conducted the literature review to find out the main challenges that are being faced by challenges related to privacy and security mainly, authentication and access control, confidentiality and integrity IOT devices users and as well as for IOT manufacturer. We highlighted seven, privacy, trust on the device and conducted a questionnaire survey from different organizations and from different research experts and ranked it accordingly.
