Big data has grown in importance in a variety of corporate and academic fields as a result of substantial changes in human behavior and lifestyles. While this focus simplifies data management, big ...data is regarded as important in many industrial areas because it can be merged with other types of data. Big data can be managed alongside other types of data, particularly in large organizations that handle a range of data types. This type of management contributes to the improvement and development of the organizational structure, as well as raising the skill level of employees in these organizations. Despite these benefits, there are numerous concerns, particularly throughout the stages of data gathering and storage, when there is a risk of hacking or leakage, as well as the difficulty of sorting and identifying data. For these reasons, big data protection is regarded as one of the most important issues discussed in this paper in order to develop an appropriate framework for protecting big data related to companies, as well as methods for dealing with this data in order to develop an appropriate strategy to protect big data security and privacy.
This study investigates the constructs and related theories that drive social capital in energy sector from the intention perspectives. This research uses theories of ‘social support’ and ‘planned ...behaviour’ alongside satisfaction and perceived value to propose a research model that drives social capital for energy sectors in Malaysia. The model reveals that the Theories of Planned Behaviour (TPB) and Social Support Theory (SST) alongside satisfaction and perceived value factors promote social capital development in energy sectors. Using PLS–SEM to analyse data gathered from energy sector employees in Malaysia, this research demonstrates that social capital is present when there is trust and loyalty among the users and positively effects energy sectors in terms of the productivity, effectiveness, efficiency and profitability. The study also contributes to the understanding of individuals' use of social capital in energy sector. A survey is adapted and distributed to 100 respondents as a mean to study on the validity and reliability of the research factors. Results indicate that all seven hypotheses proposed significantly influence social capital.
The development teams who are geographically spread, culturally mixed and mainly depend on information and communication technology (ICT) for communication is defined as a global virtual teams ...(GVTs). Despite the advancement of technologies, achieving the efficient performance of GVTs remains a challenge. The reviewed literature has highlighted the importance of training and development, organizational commitment and motivation in enhancing the performance of GVTs. This study aims to identify the key performance indicators (KPIs), measures, and variables for assisting the GVT performance in global software development projects (GSD). In addition, this study aims to measure the GVTs performance involving online training and development, organizational commitment, and motivation in GSD projects. A survey was conducted among 103 respondents. Then, the performance measurement model (PMM) for GVTs in GSD projects was proposed based on the result of the survey. Finally, the project managers validated the study model. The proposed PMM includes four major components, namely performance measurement processes, mapping strategy for performance evaluation, measurements and performance analysis. The results showed the validity of the proposed model and confirmed that the PMM can assist project managers in measuring the performance of GVTs in GSD Projects.
Today the trend is to perform software development work via distributed geographical area among team, individual or even as an organization. However, due to the global market and international ...presence of many companies, there is a need to implement a global virtual teams. The global virtual team members are gradually engaged in globalized business environments across space, time and organizational boundaries via information and communication technologies. A global virtual team relies on communication, collaboration, and information exchange are the most important criteria in global virtual teams' operations. The purpose of this paper is to answer two research questions. The first research question is to identify the factors affecting global virtual teams' performance. A systematic literature review was conducted to answer the first research question. The second research question is on what the rank of the factor affecting the global virtual teams' performance according to their level of effect on global virtual teams' performance. Online survey was conducted within 103 developers and IT managers from eight IT companies to answer the second research question. The Statistical Package for Social Science (SPSS 22) was used to analyze the collected data. In this study, we investigated factors that affect global virtual teams' performance; factors considered include cultural differences, language problems, time-zone differences, team size, technical problems, lack of trust, lack of sufficient training, and ICT problems. Also the findings indicated that lack of sufficient training is the highest level of effect on global virtual teams' performance. On the other hand, team size is the lowest level of effect on global virtual teams' performance.
Virtual teams are established to during software development environment. Virtual team members are gradually engaged in globalized business environments across space, time and organizational ...boundaries with links ensured by information and communication technologies. A virtual team relies on communication, collaboration, and information exchange is the most important criteria in virtual teams operations and their efficiency directly influences team performance. The aim of this paper is to identify the factors of selecting and using of technologies within virtual teams communication to improve virtual team communication to enhance the virtual team performance. This researcher uses systematic literature review by Kitchenham to review existing literature on the issues and implementation of virtual team members. In this review 22 papers were analyzed to answer the research questions.
