The Impact of Quality Management Strategies on Project Performance and Sustainability

Quality management strategies are vital for improving coffee farming productivity and sustainability, yet there is limited research on their specific impact in Northern Province, Rwanda. This gap hinders the effective adoption and scaling of successful coffee farming projects, particularly within the Sustainable Growers initiative. The purpose of this study was to establish the influence of Quality Management Strategies on the performance of coffee farming projects in Northern Province, Rwanda. The study adopted Total Quality Management (TQM) Theory and Sustainability Theory. The research employed both descriptive and correlational designs with a target population estimated at 531 people, composed of 4 project managers, 25 farmer cooperative representatives from five women cooperatives, and 502 farmers trained under the project. A sample of 84 respondents was determined using Solvi’s formula. Data collection was conducted using questionnaires, interviews, and document reviews. A pilot test was conducted with 15 respondents to determine the instrument's ability to produce consistent results over time. The reliability of the research instrument (questionnaire) was assessed using Cronbach’s Alpha. Descriptive and inferential statistics, including regression and correlation analysis, were conducted at a significance level of 0.05 using SPSS version 28 the obtained results revealed that, quality planning (p = 0.001 < 0.05), quality assurance (p = 0.002 < 0.05), quality control (p = 0.003 < 0.05) and, quality improvement (p = 0.002 < 0.05) have significant influence on project performance, therefore, rejecting the Null hypotheses. The study concludes that quality planning, assurance, control, and improvement practices are essential for the success of coffee farming projects, significantly enhancing performance, productivity, and the livelihoods. The study recommends prioritizing comprehensive planning, improving monitoring and evaluation, implementing regular inspections and corrective actions, and fostering continuous innovation and training to enhance the success and sustainability of future coffee farming projects. The study suggests that future researches could explore the impact of stakeholder engagement on project performance and assess the role of evolving technology, such as remote sensing and mobile apps, in improving quality control and monitoring in coffee farming, focusing on their feasibility, costs, and effectiveness.financial monitoring mechanisms to ensure efficient resource allocation. Future research needs to examine the effects of community involvement on project implementation of water supply projects.
