“…For this study, the reason for adopting the questionnaire owes to its appropriateness in measuring the success of agile implementation. Examples of other similar studies are (16,17) . The survey questionnaire was divided into two parts: the first part comprised the questions related to respondent information while the other part comprised the project management factors, as shown in Table 1.…”

“…Next, the researchers statistically compared the effect of the traditional and agile methodologies using the six-point star model and explored the interrelationship between these factors. The outcome suggested that agile methodologies are sound for smaller tasks, while traditional methodologies are better for medium-and-large scale tasks (16). "AZ-Model", is introduced to develop the software on the basis of six-pointed star model (17).…”

Software cost management is a significant feature of project management. As such, it needs to be employed in a project or line of work. Software cost management is integral to software development failures, which, in turn, cause software failure. Thus, it is imperative that software development professionals develop their cost management skills to deliver successful software projects. The aim of this study is to examine the impact of cost management success factors with project management factors and three agile methodologies -Extreme Programming (XP), Scrum and Kanban methodologies which are used in the Pakistani software industry. To determine the results, the researchers applied quantitative approach through an extensive survey on 52 agile software development companies in Pakistan. Statistical techniques, such as Pearson's correlation and mean and standard deviation were performed to examine the results. Following this analysis, we found that cost management has a positive effect on other project management factors, which are schedule, scope, risk, resources, and quality. Furthermore, it is determined that, in general, Kanban performed better than both, Scrum and XP in the context of project management 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.

“…Ince's model consists of the core phases of “change request,” “rejection,” “batch,” “implementation,” and “updating.” Each change request will forward to the change control board (CCB), and they will further take the final decisions after evaluating the change through all the phases of the model . This model covers different aspects of RCM but is missing the verification phase of the implemented changes . Therefore, it is challenging to verify whether a change implemented in the system is working accordingly or not.…”

The phenomenon of global software development (GSD) has been adopted by a majority of the software development firms to achieve the significant benefits it offers. However, there are many challenges faced by the GSD organizations, which are mainly related to requirements change management (RCM). The key objective of this study is to identify the challenges of RCM process in GSD domain. The systematic literature review (SLR) approach has been used to investigate the challenges of RCM activities, and a total of 30 challenges were identified. We have further classified the identified challenges in the domain of client and vendor GSD organizations, aiming to provide a clear understanding of the RCM process and its challenges in the context of both types of GSD organizations. The identified challenges were also categorized into three core types according to the organization size (small, medium sized, or large), which highlights the significance of each challenge for a specific organizational size. In addition, the criticality of the identified challenges was assessed using the criteria of challenges having a frequency greater than or equal to 50%. According to the findings of this study, a framework is provided that could help GSD organizations address the problems related to RCM in a GSD environment.
