Abstract
This study examined the effect of project quality management on project success in government housing building projects in Addis Ababa, Ethiopia, using the Akaki Kality Werku Site 5000
Housing Project as a case study. The study was motivated by persistent challenges in housing projects, including quality deficiencies, schedule delays, cost overruns, and stakeholder
dissatisfaction, despite the growing emphasis on quality management practices. An explanatory research design with a quantitative approach was employed. Data were collected from 54
project professionals, including project managers, engineers, consultants, supervisors, and quality personnel, using structured questionnaires and a census sampling technique. The
collected data were analyzed using descriptive statistics, Pearson correlation, and multiple linear regression with the aid of SPSS Version 27. The findings revealed that project quality
management practices were generally implemented at a satisfactory level within the project. Correlation analysis indicated positive and significant relationships between Quality Planning,
Quality Assurance, Quality Control, and Project Success. The regression results showed that the overall model was statistically significant (R² = 0.746, F = 48.923, p < 0.001), explaining 74.6%
of the variation in project success. Quality Assurance (β = 0.611, p < 0.001) and Quality Control (β = 0.308, p = 0.006) had significant positive effects on project success, whereas
Quality Planning (β = 0.004, p = 0.926) had no statistically significant effect. The study concludes that effective Quality Assurance and Quality Control practices are critical
determinants of project success and recommends strengthening quality management systems throughout the project life-cycle to improve housing project performance
