The study aimed to examine the impact of Supply Chain Management practices, including supplier relationships, customer relationships, internal processes, and information sharing, on competitive manufacturing priorities through Information Technology, represented by hardware and equipment, human resources, and software. It also sought to determine the levels of Supply Chain Management implementation, Information Technology implementation, and achievement of competitive manufacturing priorities in the industrial companies of Hayel Saeed Anam & Co.

The study targeted all employees in the senior and middle management levels of the industrial companies under investigation. The study population consisted of 326 employees, who were all surveyed. A total of 308 questionnaires were retrieved, of which 301 were valid for statistical analysis. The study adopted a descriptive-analytical approach and used a questionnaire as the primary data collection instrument. The data were statistically analyzed using SPSS 24, while Structural Equation Modeling was conducted using AMOS 24.

The findings revealed a partial mediating role of Information Technology in the relationship between Supply Chain Management practices and competitive manufacturing priorities in the industrial companies under study. The findings also indicated a high level of attention to the implementation of Supply Chain Management practices. Customer relationships ranked highest in terms of implementation, while supplier relationships ranked lowest.

The findings further showed a high level of attention to the implementation of Information Technology across all its dimensions. Hardware and equipment ranked highest in implementation, whereas software ranked lowest. The results also indicated a high level of achievement of competitive manufacturing priorities, with quality ranking highest and cost ranking lowest.

The study recommended strengthening attention to all dimensions of Supply Chain Management in the industrial companies under study to achieve a more integrated and sustainable supply chain. It also recommended supporting and strengthening strategic partnerships with suppliers by establishing clear communication channels and performance-based evaluation mechanisms to improve the effectiveness of supplier relationships.

The study further recommended continuing to strengthen Information Technology infrastructure by adopting advanced digital tools that support faster and more accurate decision-making, as well as increasing investment in software development and updating systems in line with industrial operational requirements to enhance integration and operational efficiency.

The study also emphasized the importance of strengthening integration among the four competitive manufacturing priorities—cost, quality, flexibility, and delivery—through balanced strategies that achieve an optimal balance between cost reduction and maintaining quality, while investing in operational flexibility and improving delivery speed and efficiency. Such measures would enhance the organizational and strategic maturity of the industrial companies and strengthen their ability to compete and respond sustainably to market requirements.

Researcher Adnan Hamoud Yahya Abasher was awarded a PhD degree in Business Administration from the Center of Business Administration – Sana’a University, for his dissertation titled: The Role of Creative Leadership in Improving Competitive Capabilities Through Total Quality Management: A Field Study on Money Exchange Networks in the Republic of Yemen, under the supervision of Assoc. Prof. Nabil Mohammed Ali Al-Alfi. The dissertation defense was held on Sunday, January 18, 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 creative leadership, through its dimensions of problem-solving and decision-making, initiative and proactiveness, originality and innovation, and effective communication, in improving competitive capabilities through total quality management, represented by customer focus, continuous improvement, training, top management support, and teamwork. The study also sought to investigate the role of total quality management in improving the competitive capabilities of money exchange networks in the Republic of Yemen.

The study population consisted of 400 individuals representing 7 money exchange networks (companies) out of a total of 16 networks. The study sample comprised 363 respondents, selected using the proportionate stratified sampling method.

The findings revealed a statistically significant role of creative leadership in improving the competitive capabilities of money exchange networks. The results showed that effective communication had a positive and significant effect on competitive capabilities, while no statistically significant effect was found for problem-solving and decision-making, initiative and proactiveness, or originality and innovation in improving the competitive capabilities of money exchange networks.

The findings also indicated that the level of competitive capabilities among Yemeni money exchange networks was high. In addition, creative leadership was found to have a statistically significant effect on total quality management, while total quality management also had a statistically significant effect on improving competitive capabilities. Furthermore, a statistically significant relationship was identified among the three variables—creative leadership, total quality management, and competitive capabilities. The inclusion of total quality management as a mediating variable in the relationship between creative leadership and competitive capabilities had a substantial effect on this relationship, as total quality management contributed to increasing the overall effect of creative leadership on competitive capabilities.

The study presented a number of recommendations, most notably the need for owners and managers of money exchange networks to select, appoint, and attract creative leaders who are capable of fostering a culture of creativity among employees, given their central role in promoting employee innovation and excellence. It also recommended adopting innovative methods for identifying talents and developing employees’ skills, empowering managers and employees with greater authority to introduce new initiatives in performing their duties, and reducing centralization in decision-making.

The study further recommended that the leadership of money exchange networks devote greater attention to creating an organizational environment that encourages employees to propose innovative ideas and services, develop leaders’ skills in using modern tools for problem-solving, and address areas that received lower levels of performance, particularly the use of modern problem-solving tools.

With regard to total quality management, the study recommended developing a quality manual for money exchange networks and activating the role of quality management in conducting periodic customer surveys to identify opportunities for improvement. It also emphasized the importance of promoting a culture of total quality through training programs, workshops, and specialized seminars, as well as establishing dedicated development units within money exchange networks to improve their programs and services in accordance with quality standards. The study also highlighted the importance of regularly evaluating customer satisfaction due to its significant role in improving and developing services.

The study adopted a descriptive-analytical approach. For data collection, a questionnaire was designed and administered to employees of Yemeni banks in the capital, Sana’a. The study population consisted of 1,537 employees, while the study sample comprised 350 respondents, selected using simple random sampling.

A number of statistical methods were employed to analyze the data, test the study hypotheses, and examine the relationships among the study variables using the Statistical Package for the Social Sciences (SPSS) and AMOS.

The findings revealed that the level of implementation of the Trade in Services Liberalization Agreement was high, as was the level of banking service quality and the level of competitiveness achieved by Yemeni banks. The findings also demonstrated a statistically significant effect of implementing the Trade in Services Liberalization Agreement on the competitiveness of Yemeni banks, as well as a statistically significant effect of the agreement on banking service quality.

Furthermore, the study found a statistically significant effect of banking service quality on the competitiveness of Yemeni banks. It also demonstrated a significant effect of implementing the Trade in Services Liberalization Agreement on the competitiveness of Yemeni banks through the development of banking service quality, highlighting the important role of service quality in strengthening competitiveness.

Based on the findings, the study recommended increasing attention to the implementation of the Trade in Services Liberalization Agreement across its dimensions, including cost leadership strategy, differentiation strategy, focus strategy, human resources, and technological requirements.

The PhD Viva-Voce Committee consisted of Assoc. Prof. Dr. Abdulrazzaq Mohammed Al-Marani, Sana’a University, as Internal Examiner and Chair; Assoc. Prof. Dr. Mohammed Abdullah Al-Ashwal, Al-Bayda University, as External Examiner and Member; and Prof. Dr. Sinan Ghaleb Al-Marhadi, Sana’a University, as Supervisor and Member.
