Despite the critical role of internal audit units along with various strategies undertaken to enhance this role, presence of fraud, corruptions and other unethical practices still discontented with the auditing units inability to undertake auditing functions effectively without being detected and become a common phenomenon in parastatal organizations of Tanzania. This paper determined the role of internal audit on procurement performance. Specifically, it determined the influence of competence, independence, and management support on procurement performance and recommended strategies for improving the same. Quantitative approach was adopted and data were drawn from an explanatory research design sampled with 94 parastatals of Dar es Salaam through questionnaires from head of departments particularly user departments. Descriptive data analysis were employed to get mean and standard deviation of the findings, whereby data were summarized using frequency distribution tables and finally multiple regression model was used to analyze the data. The findings showed that independence and management support had a significant positive association with procurement performance at p<0.05. Competence had a non-significant positive association with procurement performance. The study recommended managements of parastatal organizations to provide training opportunities to the internal audit sections, ensuring the internal auditors to exercise their duties with autonomy as well as be free from any type of influence. Furthermore,management should ensure that internal audit sections are given full support to execute their functions thereby ensuring satisfactory procurement performance

The study aimed to identify the obstacles preventing higher learning institutions in the Dar es Salaam region from adopting sustainable procurement. In particular, the study sought to ascertain how the legal framework, supplier awareness, staff knowledge, and top management support affected sustainable procurement in the construction projects of higher learning institutions in the Dar es Salaam region. 156 employees who worked as estate officers and procurement specialists made up the study's sample, whereby the Yamane (1967) Formula was used to determine the study's sample size, which was 112 participants. However, only 101 questionnaires were collected, filled out, and returned for analysis. The data were collected using a closed-ended questionnaire using the drop-and-pick method. The data were analyzed using descriptive statistics, where the mean and standard deviation were calculated. At the same time, inferential analysis was done by using multiple linear regression analysis after testing the reliability and validity of the data and the assumptions of multiple regression analysis, including normality, linearity, homoscedasticity, and multicollinearity. The research was carried out using IBM SPSS version 26. According to the study's findings, all four tested variables, supplier awareness, management support, legal framework, and staff knowledge, have a significant positive relationship with sustainable procurement. Management in higher learning institutions should consider these variables to ensure sustainable procurement within their organization.

The study aimed to examine the effect of political interference on procurement performance in Tanzania's parastatal organization. It was specifically intended to investigate the impact of political interference on the contract award, project allocation, and legal framework implementation on procurement performance and make some recommendations for improvement. The data were collected from heads of departments at 93 parastatal organizations in Dar es Salaam using structured questionnaires. The study's population consisted of 712 respondents, with a sample size of 256 randomly selected, but only 241 questionnaires were returned, completed, and used for analysis. The data were descriptively and inferentially analyzed using a multiple regression analysis with the help of SPSS version 26. The finding shows that political interference in contract award and legal framework implementation negatively influences procurement performance. In contrast, political interference in project allocation positively impacts procurement performance. The study implied that the procuring entity should ensure that politicians were not involved in the procurement process and that only authorized officers were allowed to participate.

This study aimed to examine the factors that affect the procurement performance of Tanzania’s parastatal entities. It examined the impact of political interference and staff competency on procurement performance. The questionnaire was used to collect data from heads of departments from 93 state-owned organizations in the Dar es Salaam Region as part of an explanatory research approach. The sample of 258 respondents was randomly selected from the population of 712 heads of departments. However, 241 questionnaires were collected from the respondents. The data were descriptively evaluated to establish the mean and standard deviation. The data were compiled using frequency distribution tables before being analyzed using multiple regression analysis. This study shows that political interference has a negative influence on procurement performance, whereas staff competency has a positive impact on procurement performance. The study implied that political influence in the procurement process should be avoided to the greatest extent possible because of its adverse effects and that staff competency should be stressed to give staff members the new skills and competencies needed to solve procurement difficulties.

This study mainly assumes that procurement is a kind of special competence which, if acquired, may sustain industrial competitiveness. Intention of this study is to explain influence of procurement competencies on enhancing dynamic industrialisation in Tanzania. The multiple regression analysis was used to determine effects of procurement competencies on embracing dynamic industrialisation in Tanzania. A survey on manufacturing firms was undertaken in examining relationships between procurement competencies and dynamic industrialisation in Tanzania using administration of questionnaire while data were collected were analysed through descriptive statistics and multiple regression analysis. Findings suggested that limited technical procurement competencies and procurement behavioural competencies when interrelated with innovative capability, technological capability, government intervention and change management significantly affects sustainable procurement competencies on embracing dynamic industrialisation in Tanzania. The study’s findings imply that there is limited understanding regarding the role procurement competencies on embracing dynamic industrialisation in Tanzania. This article suggests solutions which procurement professionals and organisations can implement in order to unlock the potential value in the dynamic industrialisation in Tanzania.
