E-PROCUREMENT PRACTICES AND PERFORMANCE OF ROADS CONSTRUCTION PROJECTS IN KENYA. A CASE STUDY OF KENYA NATIONAL HIGHWAY AUTHORITY, KAKAMEGA COUNTY
(management university of africa, 2023-11) Wesley Koech; Dr. Paul Machoka
The critical pre-planning stages for road construction projects encompass tasks such as planning, analysis, design, earthwork, paving, implementation, quality control assessment, and task interdependency scheduling. There has been a visible setback in implementation due to timely challenges in completion of road projects construction systems despite reforms in procurement regulations in regard to PPDA of 2005. The primary focus of this study was to investigate the how e-procurement practices has affected the performance of roads construction projects in Kakamega County Government's Western Region with reference to the Kenya National Highways Authority. To do so, the study established the effects of e-procurement practices (e-tendering, e-sourcing, e-valuation, and e-submission) on performance of roads construction projects under KeNHA in Kakamega County. The study was guided by the Resource Based View theory, Dynamic Capability Theory and Unified theory of acceptance. Study findings revealed that e-sourcing had significant influence on performance of road construction projects (t-statistic=19.927, p-value=0.002< 0.05). E-tendering had a significant influence on performance of road construction projects (t statistic=25.674, p-value=0.045< 0.05). Study revealed that e-evaluation had significant influence on performance of road construction projects (t statistic=3.183, p-value=0.006 < 0.05). Lastly, the study revealed that the e-submission had a significant influence on performance of road construction projects (statistic=6.117, p-value=0.000 < 0.05). Measures related to the e-procurement system should be improved, and management should take the lead in the implementation of electronic procurement. This will improve the reduction of supply chain risks and make supplier performance more beneficial for KeNHA as well as road construction projects. The results of this study will inform strategic decisions the management may need to make to ensure effective application of e-procurement in KeNHA as well as other organizations.

The study used both quantitative and qualitative methods in a descriptive mixed-method design. Through organized surveys, document inspections, and interviews, information was gathered from 240 Kenya Ports Authority workers. The Statistical Package for the Social Sciences (SPSS) version 28 was used to analyze the data, utilizing multiple regression analysis, correlation, and descriptive statistics. The study established that procurement inefficiencies, limited transparency, and high transaction costs affected organizational performance. The theoretical framework emphasized the influence of internal capabilities, transaction efficiency, and technology acceptance on procurement performance. The literature review revealed that electronic procurement enhances operational efficiency, accountability, and cost reduction within public institutions. The conceptual framework demonstrated the interrelationship link procurement procedures and procurement success, demonstrating how digital solutions can enhance institutional results. The population characteristics, sampling techniques, and data collection tools were all described in depth in the research design. Cronbach's alpha, expert evaluation, and pilot testing were used to verify validity and reliability. The ethical precepts of secrecy, anonymity, and informed consent were upheld. The findings revealed that the four e-procurement practices jointly explained 69.2% of the variation in procurement performance at KPA (R² = 0.692). Individually, e-tendering contributed 22.8%, e-auctioning 18.6%, e-cataloguing 15.4%, and e-invoicing 12.4% to procurement performance. The results further showed that procurement planning moderated these effects and emerged as the strongest predictor of performance outcomes. The adoption International Journal of Management and Leadership Studies, 2026 Volume 6 Issue 1 940 of e-procurement improved efficiency, enhanced transparency, and reduced transaction costs. Findings showed increased effectiveness, more openness, and decreased procurement costs resulting from the adoption of electronic procurement systems. The study concluded that improving staff competency, strengthening contract management, ensuring adequate resource allocation, and institutionalizing procurement planning enhance procurement performance. Recommendations included continuous capacity building, integration of risk management practices, and increased investment in ICT infrastructure to sustain e-procurement effectiveness. The research provided empirical evidence on the significance of electronic procurement practices in improving efficiency, cost control, and accountability within the Kenya Ports Authority. The study contributed to policy formulation, institutional development, and academic discourse on digital transformation in public procurement systems.

(management university of africa, 2023-11) Jared Okoth Awuor; Dr. Paul Machoka
To determine the level of risk default that a client or household presents and assign a risk score to each client, to ascertain the validity of the credit score and household borrowing, to examine trends in credit portfolio diversification, to guarantee adequate controls over credit score, the study aims to examine and establish personal credit scores and access to affordable credit in accessing affordable credit, a case study of the NCBA Bank Group PLC Kenya. Targeting 170 personnel, namely the corporate risk manager, project manager, branch manager, credit risk manager, and operations manager of the NCBA Bank, Kenya, a descriptive study approach was used. 30% of the workers in a survey of 35 branches out of 64 branches were used in the study (51 employees). Both primary and secondary data were employed in the investigation. The primary data will be administered with the questionnaire, and data presented in form of tables and pie charts. It is recommended that in order to assess specific banks’ capacity for portfolio risk management and the creation of expert-based scorecards, focused consultations with those banks are necessary. In addition, there is need for launching a large-scale effort to standardize the gathering of financial statement data, ratio computations, collateral quality measurements (type, loan to-value ratio, lien position), and performance data for loans and deposits. This would eventually allow for the creation of a pooled credit scorecard that includes not only credit bureau data but also the other essential components of a strong NCBA Bank, Kenya scoring model. The days of implementing broad-based policies are being replaced by in-depth evaluations of the market circumstances and a better effort to comprehend the increasingly complex wants of consumers. Additionally, it must be made known that the Credit Information Sharing Mechanism opens up new avenues for obtaining official credit.

STRATEGIC IMPEDIMENTS TO CONSOLIDATION IN GHANA’S OIL MARKETING SECTOR: AN EMPIRICAL STUDY
(management university of africa, 2025-11) Ahmed Mohamed; Dr. Paul Machoka
This study investigated the strategic impediments to mergers and acquisitions (M&A) in Ghana's oil marketing sector. Using a cross-sectional design and a quantitative approach, data was collected from 255 oil marketing companies (OMCs) through a survey. The results indicate that regulatory complexity significantly impedes M&A activities, while legal uncertainty does not have a significant impact. Economic stability and financial health positively influence the likelihood of successful M&A, but access to capital exhibits a surprising negative relationship. Neither strategic alignment nor organizational readiness significantly predicts M&A success. However, market fragmentation and competitive intensity strongly influence the feasibility of consolidation efforts. Robustness checks confirm the reliability of the findings. The study highlights the importance of regulatory frameworks, economic conditions, and market dynamics in shaping M&A outcomes and provides practical insights for stakeholders in the oil marketing sector. Policymakers are encouraged to streamline regulatory processes to facilitate smoother M&A transactions, ultimately fostering industry growth and competitiveness.
