Researcher Majed Mohammed Saleh Al-Kumaim ‎was awarded a PhD degree in Business Administration ‎for his dissertation titled: The Role of Strategic Agility in Achieving Competitive Advantage through Entrepreneurial Orientation in Yemeni Banks: A Field Study, which was submitted to the Center of Business Administration –Sana’a University. The dissertation defense was held on Tuesday, August 11, 2026.

The PhD Viva-Voce Committee, which was formed based on a resolution issued by the Graduate Studies and Scientific Research Council, consisted of the following:

The study aimed to examine the role of strategic agility and its dimensions—vision and goal clarity, strategic sensitivity, core capabilities, shared responsibility, and appropriate decision-making—in achieving competitive advantage through entrepreneurial orientation in Yemeni banks.

It also sought to determine the extent to which the mediating variable of entrepreneurial orientation—with its dimensions of creativity and innovation orientation, proactiveness, competitive aggressiveness, autonomy, and risk-taking—mediates the relationship between strategic agility and competitive advantage in Yemeni banks.

The study adopted a descriptive-analytical approach. The study population comprised 700 senior, middle, and executive management leaders working in 16 Yemeni banks in the Capital Secretariat, Sana’a. The sample consisted of 350 participants, representing 50% of the population, in accordance with the statistical requirements for Structural Equation Modeling (SEM), which require a minimum of five observations for each of the 70 questionnaire items.

The researcher developed a questionnaire as the primary data collection instrument and used SmartPLS for statistical analysis and Structural Equation Modeling. The questionnaire was distributed in accordance with each bank’s policies through its human resources departments to a purposive, non-probability sample.

The findings showed that the direct effect of strategic agility on competitive advantage in Yemeni banks was 0.211. In the presence of the mediating variable of entrepreneurial orientation, the effect increased by approximately three and a half times, reaching a total effect coefficient of 73.1%, and this effect was statistically significant. The findings also showed that entrepreneurial orientation partially mediated the relationship between strategic agility and competitive advantage.

Regarding the sub-dimensions of strategic agility, the findings showed statistically significant effects. The effect of vision and goal clarity on competitive advantage was 0.164, increasing by approximately four times in the presence of entrepreneurial orientation, with a total effect coefficient of 64.9%. Entrepreneurial orientation partially mediated the relationship between vision and goal clarity and competitive advantage.

The effect of strategic sensitivity on competitive advantage was 0.151, increasing by more than four times in the presence of entrepreneurial orientation, reaching an effect coefficient of 62%. The mediation between strategic sensitivity and competitive advantage was partial.

The effect of core capabilities on competitive advantage was 0.153, increasing by approximately four and a quarter times in the presence of entrepreneurial orientation, reaching an effect coefficient of 64.6%. Entrepreneurial orientation partially mediated the relationship between core capabilities and competitive advantage.

The findings also demonstrated a statistically significant effect of shared responsibility on competitive advantage, with full mediation by entrepreneurial orientation in Yemeni banks and a total effect coefficient of 57.7%. Likewise, appropriate decision-making had a statistically significant effect on competitive advantage, with full mediation by entrepreneurial orientation and a total effect coefficient of 62.7%.

The study recommended that Yemeni banks organize training courses in strategic management, with particular emphasis on strategic agility as a contemporary management philosophy, as well as training employees at various management levels in entrepreneurship and entrepreneurial orientation. Such training would familiarize employees with their concepts, dimensions, components, and characteristics and develop their related skills, given their importance as sources of competitive advantage.

The study further recommended clarifying the complementary relationship between strategic agility and entrepreneurial orientation and their joint role in achieving competitive advantage, while training employees in sound practices related to entrepreneurial orientation and strategic agility.

It also emphasized the importance of Yemeni banks, amid continuous and accelerating environmental changes, focusing on responding rapidly to and adapting to such changes from an entrepreneurial perspective. This should include pursuing competitive advantage by improving the quality and delivery of banking services, leveraging technological developments and communication technologies to meet customers’ needs and preferences in ways compatible with their purchasing power, and providing diverse services that address the needs of different customer segments.

Mr. Hussein Abdullah Ali Ahmed Bin Hafiz Al-Hashemi has successfully obtained his PhD degree in the Philosophy of Business Administration from the Center of Business Administration Studies, Sana’a University. His dissertation, titled: “The Role of Strategic Leadership in Achieving Competitive Advantage Through Strategic Vigilance in the Yemeni Telecommunications Sector“, was supervised by Associate Professor Dr. Mohammed Abdullah Al-Ashwal.

The Viva-Voce Committee, formed based on a resolution issued by the Post-Graduate Studies and Scientific Research Council, consisted of the following members:

1. Prof. Amal Mohammed Al-Mujahid – External Examiner and Chair, Dhamar University.
2. Assoc. Prof. Fadhl Mohammed Al-Mahmoudi – Internal Examiner, Sana’a University.
3. Assoc. Prof. Mohammed Abdullah Al-Ashwal – Supervisor, Al-Bayda University.

The Viva-Voce was attended by a number of academics, researchers, students, and interested participants, as well as several colleagues and family members of the researcher.

This study aimed to investigate the role of strategic leadership in achieving competitive advantage through strategic vigilance in the Yemeni telecommunications sector. It also sought to assess the level of strategic leadership practices, strategic vigilance, and competitive advantage within the sector under study. The study adopted a quantitative approach using both descriptive and analytical methods and employed a questionnaire as the primary instrument for data collection.

The study population comprised all employees occupying leadership and supervisory positions in the Yemeni telecommunications sector, totaling 790 employees across five telecommunications organizations located in Sana’a, Yemen: the Public Telecommunications Corporation (PTC), Yemen Mobile, Sabafon, YOU, and TeleYemen. A stratified random sample of 316 respondents was selected, of which 286 valid questionnaires were returned and deemed suitable for analysis, yielding a response rate of 93.67%.

Covariance-Based Structural Equation Modeling (CB-SEM) was employed to analyze the proposed relationships among the study variables. Statistical analyses were conducted using the Statistical Package for the Social Sciences (SPSS) version 27 and AMOS version 25 to achieve the study objectives and test its hypotheses.

The findings revealed that strategic vigilance plays a statistically significant partial mediating role in the relationship between strategic leadership and competitive advantage. The results also indicated statistically significant positive direct effects among the study variables, whereby strategic leadership positively influences both strategic vigilance and competitive advantage, while strategic vigilance positively contributes to the achievement of competitive advantage. At the dimensional level, commercial vigilance was found to play a statistically significant partial mediating role in the relationship between strategic leadership and competitive advantage. In contrast, neither technological vigilance nor environmental vigilance demonstrated a statistically significant mediating effect.

The study concluded that achieving competitive advantage in the Yemeni telecommunications sector requires an integration of strategic leadership practices and strategic vigilance mechanisms. Moreover, commercial vigilance represents the most influential dimension of strategic vigilance in strengthening this relationship, enabling telecommunications companies to better sense and respond to market changes, thereby enhancing their ability to achieve and sustain competitive advantage
