The study was guided by the following specific objectives; To determine the influence of Supplier Responsiveness, Supplier Reliability, Supplier Quality and Supplier Cost on procurement performance of parastatals in Mombasa County. The study draws from several established theories in procurement, including Supplier Selection Decision Theory, Resource Dependency Theory, Transaction Cost Theory, and Means-End Theory. Targeting a group of 308 individuals employed in parastatals in Mombasa County, 174 valid responses were collected, adhering to Yamane allocation sample equations to determine the sample size. Data collection involved the distribution of questionnaires, followed by rigorous editing to ensure accuracy and consistency. Descriptive statistics were employed for analysis, supported by multiple regression analysis to assess the influence of supplier selection criteria on procurement performance. The diagnostic tests conducted in this study aimed to assess several key assumptions underlying regression analysis. Autocorrelation was evaluated using the Durbin-Watson test, which indicated presence of independence of errors. Multicollinearity was examined using variance inflation factor and no multicollinearity issues were present. Normality was assessed visually using P-P plots confirming the normal distribution of residuals. Linearity was confirmed through scatter plots and ANOVA analysis, demonstrating linear relationships between independent and dependent variables. Homoscedasticity was verified by examining the plot of studentized residuals against unstandardized predicted values, showing no evidence of heteroscedasticity. These diagnostic tests validate the reliability of regression analysis results and support the influence of supplier selection criteria on procurement performance. The study achieved a response rate of 116 which is 66.7% which is dimmed excellent. The study identified strong positive associations between procurement performance and four key supplier-related variables: responsiveness, reliability, quality, and cost. Supplier responsiveness and reliability were consistently viewed as crucial, with minimal variance in respondent opinions, emphasizing their role in ensuring efficient and effective procurement processes. Supplier quality also positively influenced procurement performance. Supplier cost was similarly linked to improved procurement outcomes, but with a broader range of opinions, suggesting the need for a balanced approach that considers cost alongside other critical factors like quality and reliability. Additionally, the research suggests potential future investigations, including exploring alternative supplier selection criteria's influence on organizational performance across different contexts 2024-01-01T00:00:00Z http://ir.tum.ac.ke/handle/123456789/17654 INFLUENCE OF SUPPLY CHAIN INTEGRATION ON THE OPERATIONAL PERFORMANCE OF FORMAL MANUFACTURING FIRMS IN MOMBASA COUNTY OMAR, FARHANA FAIZ The study was guided by the following specific objectives; to determine the influence of technology integration on operational performance of formal manufacturing firms in Mombasa County, to establish the influence of customer integration on operational performance of formal manufacturing firms in Mombasa County, to determine the influence of product integration on operational performance of formal manufacturing firms in Mombasa County and to determine the influence of process integration on operational performance of formal manufacturing firms in Mombasa County.

The target population of the study consisted of 100 general operation managers 50 Head of Procurement Section and 100 warehouse managers in the 50 selected manufacturing firms in Mombasa County. The sample size was determined using Yamane allocation sample formulae to obtain 152 respondents. The researcher used questionnaires as a tool for data collection. The questionnaires contained close ended questions that solicited respondents’ views. Data analysis involved sorting, coding and transforming data into statistical information for the purpose of analysis and interpretation by use of SPSS. This study used quantitative data specifically descriptive statistics. Regression analysis was used. The findings were presented in the form of tables and percentages. Normality testing involved examining whether the residuals of the regression model followed a normal distribution, with normal QQ plots revealing a close alignment between observed and expected data points, indicating normal distribution. Additionally, the Shapiro-Wilk test confirmed normality for all variables. Multicollinearity was assessed using variance inflation factor (VIF), with values indicating no issues. Heteroscedasticity was checked using Breusch-Pagan and Koenker tests, which showed no significant problems. Autocorrelation was tested using the Durbin-Watson statistic, with results indicating no autocorrelation. Finally, linearity was assessed through Sig. linearity and Sig. deviation from linearity tests, confirming the presence of a linear relationship between variables. The findings revealed that technology integration significantly enhances operational performance by improving operational efficiency and effectiveness. Customer integration practices were found to have a strong positive influence on operational performance by fostering customer relationships and meeting their needs. However, product integration had a limited influence on operational performance, suggesting a need for organizations to realign their product strategies. Process integration emerged as a significant determinant of operational performance, highlighting the importance of optimizing processes and fostering collaboration across departments.

Companies that had aligned their existing supply chains were expected to benefit from a sustainable supply chain. The performance and long-term viability of the supply chain depended on the implementation of eco-friendly practices. The study aimed to examine the supply chain performance of Level 4 hospitals in Mombasa County to determine whether and how sustainable supply chain management practices could enhance supply chain performance. The research had four specific objectives regarding supply chain performance at Level 4 hospitals in Mombasa County: (1) it evaluated the effect of CSR on supply chain performance; (2) it examined the effect of green purchasing on supply chain performance; (3) it explored the result of reverse logistics on supply chain performance; and (4) it assessed the effect of social and resilient supply chain practices. This study was guided by the following theories; of dynamic capacities, the stakeholder theory, the supply chain integration, and the systems. A descriptive research strategy was employed for this investigation. The study included a survey of the twenty Level 4 hospitals in Mombasa County. Data was gathered through questionnaires. The first step was a small-scale pilot test. The survey underwent a battery of validity and reliability testing. All the data collected was checked for errors and duplicates. The data was analyzed using SPSS version 26. Checks for multicollinearity and normality were conducted. Regression analysis was also used to determine the extent to which the study's variables were related to one another the study concludes its examination of sustainable supply chain management practices in Level 4 hospitals in Mombasa County. The findings reveal a positive commitment to corporate social responsibility, green purchasing, reverse logistics, social and resilient supply chain practices, underscoring their significance in healthcare supply chains.
