Purpose: The successful achievement of any project means that several of its perceived factors were attained. The success of projects depends on how the risks are mitigated and the way it is managed and controlled. This study examined project implementation management practices and their effects on the Mnazi Bay Gas Project Performance. Towards analysing the data, the study used the Resource Based Theory, Theory of Constraints, Management Theory, and Stakeholder Theory. Methodology: The study employed a descriptive approach and utilized primary and secondary research methods. The sample size for the study was 100 respondents which included residents around the project, local government leaders, political leaders as well as managers and officials managing the project. Out of 100 only 84 respondents were reached. This study employed simple random sampling and purposive sampling to recruit study sample. The quantitative data were collected through questionnaires and the collected data were analysed using descriptive analysis and presented through descriptive statistics. Findings: The study reveals a positive relationship between the successful implementation of the Mnazi Bay Gas project and its overall performance, notwithstanding the challenges associated with community involvement. The research significantly advances our understanding of how project management methods influence the project's success. furthermore, the study highlights the project's strengths, including effective implementation, skilled personnel, and clear communication channels, but also identifies weaknesses, particularly in community engagement. Moreover, the study underscores the impact of various management and implementation challenges, such as difficulties in community involvement, regulatory compliance, and environmental assessments, on the project's performance and ultimate success. Conclusion: The study leverages Resource-Based Theory to underscore the efficient utilization of available resources, demonstrating its impact on Mnazi Bay Gas project performance. It utilizes the Theory of Constraints to pinpoint and tackle critical bottlenecks within this resource-intensive project. Management Theory offers a comprehensive view of project management practices and evaluates diverse managerial approaches. Lastly, Stakeholder Theory provides a thorough analysis of stakeholder interests and involvement, shedding light on the intricate dynamics within Mnazi Bay Gas involving local and international stakeholders. This integration of theories enhances the study's analytical framework, enabling a multifaceted evaluation of project implementation practices and their influence on project performance. This study concludes that there is positive relationship between project implementation and the performance of the Mnazi Bay Gas project. Apart from challenges that were identified with regard to community involvement, the Mnazi Bay Gas project was implemented well. However, there are challenges which were identified during planning in so far as the indigenous or surrounding community of the project are concerned. They were not furnished with enough information about the project, their expectations were not met mainly employment to an uneducated and better life and the dissemination of information during planning was bias since the brochures and flyers used a foreign language which is English. Recommendations/Policy Implications: Theories enrich the study's analytical framework, facilitating a comprehensive assessment of project implementation practices and their influence on performance. Thus, with this achievement policymakers should consider resource allocation strategies to enhance project performance in resource-intensive endeavors and address critical bottlenecks within projects and implement measures to alleviate constraints. Practitioners involved in project implementation should focus on optimizing resource utilization. Practitioners should adopt a stakeholder-oriented approach, actively engaging with diverse stakeholders and considering their interests throughout the project's lifecycle.

“…Furthermore, Desai et al (2015) believed that the change orders in construction projects increase the cost between 10% to 15% of the contract value and reduce productivity from 10% to 20%. While Mhando et al (2018) reported that the increase in construction cost due to change orders in Tanzania ranged between 6%–10% of the original contract cost.…”

Purpose Change orders in construction projects may lead to an increase in time and cost highlighting the need for a systematic analysis of the causes of change orders. Each cause of change orders has a probability of occurrence and impact; therefore, there is a need to reassess the causes of change orders based on the probability and impact. The purpose of this paper is to determine the risk score for each factor and develop a model for estimating the overall change orders based on the measured and latent variables. Design/methodology/approach The research methodology consists of four parts. The first part identifies the causes of change orders in road projects from a literature review and develops the final list using the Delphi technique. The second part includes designing the final questionnaire to determine the probability and impact of each factor on the five-point Likert scale and 237 questionnaires received validity. The data were divided into training and testing sets and analyzed using AMOS software. Findings The proposed structural equation model presents an insight into the influence of measured and latent factors, which are not obvious in the traditional equations. The main cause for change orders was a change in design. Originality/value The results of this research are expected to improve the execution of road projects by identifying the main causes of the change orders and hence the project manager can develop a proper risk response plan.

“…Consequently, these have led to non-fulfillment of project objectives. Tanzania being a developing country has problems related to detrimental effects of variations in developing its public building projects [1]. In the context of Tanzania construction sector, it is observed that, instead of a project taking two years it takes more than three years with its cost doubling [2].…”
