Researcher Mohammed Abdullah Nasser Al-Bahm was awarded a PhD degree in Business Administration by the Center of Business Administration for Graduate Studies at Sana’a University for his dissertation titled: “The Impact of Enterprise Resource Planning Systems on the Transition to Smart Government Through Cloud Computing: A Field Study of Yemeni Public-Sector Telecommunications Companies.”
The PhD Viva-Voce Committee consisted of Assoc. Prof. Dr. Abdulrazzaq Al-Marani, Sana’a University, as Internal Examiner and Chair; Assoc. Prof. Dr. Ahmed Al-Rahoumi, Dhamar University, as External Examiner and Member; and Prof. Dr. Abdullah Abdullah Al-Sanfi, Sana’a University, as Supervisor’s Representative and Member.
The dissertation defense was attended by a number of academics, researchers, postgraduate students, and other interested individuals, in addition to the researcher’s colleagues and family members.
The study aimed to measure the impact of Enterprise Resource Planning (ERP) systems on the transition to smart government through cloud computing, as well as to determine the levels of ERP system implementation, cloud computing adoption, and smart government implementation in Yemeni public-sector telecommunications companies.
The study adopted a descriptive-analytical approach and used a questionnaire as the primary data collection instrument. The study population consisted of 177 employees who use ERP systems, software and applications, as well as cloud computing service providers and technical and technological support personnel in the companies under study. Given the relatively small population and the availability of comprehensive data on all its members, a census approach was adopted. A total of 177 questionnaires were distributed, of which 157 valid questionnaires were retrieved, representing a response rate of 89.0%.
The study data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) through SmartPLS, in order to test the study’s hierarchical model at two levels by evaluating both the measurement model and the structural model.
The study reached several findings, most notably that ERP systems have a significant effect on the transition to smart government through cloud computing. The findings also demonstrated significant effects of ERP systems on the transition to smart government and on the adoption of cloud computing, as well as a significant effect of cloud computing on the transition to smart government in Yemeni public-sector telecommunications companies.
The findings further indicated that the levels of implementation of the study variables—ERP systems, cloud computing, and smart government—in Yemeni public-sector telecommunications companies were at the lower end of the high level.
The study presented several recommendations, most notably that Yemeni public-sector telecommunications companies should focus on adopting new generations of ERP systems or developing the capabilities of their existing systems to incorporate supplier relationship management, customer relationship management, business intelligence, and mobile commerce. The systems should also support operations through smartphones, tablets, and social media, automate business processes, organizational information and services, make these systems accessible to all employees, and provide employees with appropriate training on their components.
The study also recommended that Yemeni public-sector telecommunications companies provide financial, technological, and human-resource support to the national cloud computing operator, Sahbcom, enabling it to provide various cloud computing services—including infrastructure, platforms, software, and information—to individuals and organizations for appropriate fees. It further recommended encouraging developers and programmers to build digital platforms and smart applications and deploy them in the cloud environment.
Finally, the study recommended that Yemeni public-sector telecommunications companies develop a strategic plan for transitioning to smart government, allocate the necessary financial, technological, and human resources, and complete the required legal, regulatory, and administrative arrangements. It also recommended leveraging the widespread use of applications, smartphones, and digital technologies by broad segments of society to provide services and information and facilitate transactions.

Researcher Abdulrahman Ahmed Mohammed Al-Mahdi was awarded a PhD degree in Business Administration by the Center of Business Administration for Graduate Studies at Sana’a University for his dissertation titled: “The Role of Digital Transformation in Services Quality Through Strategic Orientation: A Field Study in Yemeni Private Universities.”
The PhD Viva-Voce Committee consisted of Assoc. Prof. Dr. Abdulaziz Mohammed Al-Makhlafi, Sana’a University, as Internal Examiner and Chair; Assoc. Prof. Dr. Nabil Mohammed Al-Alfi, Amran University, as External Examiner and Member; and Prof. Dr. Zaid Ali Abdulkhaleq Al-Manzou, Al-Bayda University, as Supervisor and Member.
The dissertation defense was attended by a number of academics, researchers, postgraduate students, and other interested individuals, in addition to the researcher’s colleagues and family members.
The study aimed to investigate the vital role of digital transformation as a key driver of university development, with particular emphasis on service quality as the dependent variable and a decisive outcome representing a key criterion for the survival and competitiveness of Yemeni private universities. The study also examined the mediating role of strategic orientation as a link between the capabilities of digital transformation and the improvement of service quality, in addition to identifying technological and human requirements and structural barriers that limit the effectiveness of digital transformation in the targeted universities.
The study adopted a descriptive-analytical approach and used a questionnaire as the primary data collection instrument. The study population consisted of 1,311 academic and administrative leaders distributed across 35 private universities in the Capital Secretariat, Sana’a. A stratified random sample of 307 valid respondents was selected from leaders in eight targeted universities, based on the Thompson formula. The data were analyzed using SPSS and AMOS, including Structural Equation Modeling (SEM) to test the hypotheses and assess the goodness of fit of the proposed research model.
The study reached several key conclusions, most notably that Yemeni private universities demonstrated high levels of digital readiness and strategic orientation. The findings also established the critical role of transformational leadership as one of the most important drivers of digital transformation, with an influence exceeding that of physical infrastructure.
The mediation analysis demonstrated the effectiveness of strategic orientation in transmitting the effect of digital transformation on service quality. However, this effect operated through organizational goals and values, while no significant mediating effect was found through vision and mission, reflecting a genuine gap between strategic theorizing and operational performance. The study also identified a coordination gap and found that reliance on closed commercial systems hinders the achievement of national digital integration.
Based on these findings, the study recommended integrating digital strategy as an essential component of university identity and investing substantially in digital leadership and human resources. At the national level, it recommended restructuring the General Administration of Systems and Technologies at the Ministry of Education and Scientific Research and activating its supervisory role, while establishing direct coordination with the Ministry of Communications and Information Technology to adopt a unified software framework that moves beyond limited commercial solutions.
The study further recommended developing integrated platforms and establishing a national digital repository to ensure data sovereignty and security, as well as standardizing digital quality standards for higher education institutions in Yemen.
