Authors: BELAY, YOHANNES Abstract: The purpose of the study is to investigate the aircraft redelivery project management effects in the aviation operator's business, particularly in the MRO division of Ethiopian Airlines. Standardized lease agreements and their controlling system comply with projected aircraft return circumstances with lessor interest, even if a company (operator) has faith in the functioning of the rented aircraft. Ignoring return requirements might result in serious problems that impact the next lease's thrust and total business revenue. Unsatisfactory returns and redelivery frequently result in poor-quality work, which highlights how crucial it is for project managers to maintain team confidence and trust in members and input. For the lessee and lessor to operate under a mature lease arrangement, a well-executed redelivery project plan is essential. This research was conducted using data collected from Ethiopian Airlines employees through an explanatory survey design. A questionnaire was distributed to 320 employees, with 258 responses (80.625%) returned and analyzed using descriptive and inferential statistical methods. Stratified random sampling techniques were employed to select sample elements from the employees who participated in the aircraft redelivery project. The study utilized a five-point Likert scale to measure variables such as project team performance feedback and causes of redelivery delay as motivational factors affecting aircraft redelivery projects and aircraft lease management and used rating questionnaires as aircraft type, aircraft age, challenges for on-time and on-budget, and engine-related complications, and the redelivery process typically begins. Data analysis was performed using SPSS. The results revealed that aircraft type, aircraft age, project team performance feedback, engine-related complications, and challenges for on-time and on-budget are key factors influencing leased aircraft return conditions at Ethiopian Airlines MRO. The study recommends enhancing the aircraft type and aircraft age, strengthening team feedback and performance mechanisms, revising engine-related complications, and reducing the overall challenge regarding the time and cost evaluation system.

It involves anticipating unforeseen circumstances that may arise beyond the project manager's control at the project's outset. The construction industry is naturally laden with risks that can threaten the success of projects, especially in road construction initiatives carried out by private firms. The research was done at private firm called Viva Engineering PLC, a grade one engineering company, to assess existing project risk management practices at its two road construction projects. The study used a mixed-methods approach, integrating qualitative and quantitative research techniques with concurrent design research methods. In conducting the study, primary and secondary data are collected using structured survey questionnaires, interviews and other published materials. Census sampling technique was used, sample of 20 participants from the total population of 20 found 18 from two projects and two from the headquarter. Descriptive statistics were used to analyze the data gathered. The findings of the paper revealed that though Viva engineering PLC has a company policy to guide and direct managing risks the existing practice is way far from the standard stipulated in the company guidelines and procedures and to the industry level. Both the quantitative and qualitative analysis findings shows that the company lacks proper risk management in all risk management process from risk identification, analysis, risk response planning to risk control and monitoring stage. The study finds also financial, socio-political, construction, right of way, and material risks are the top risks of high probable occurrence and high impact on the project quality, cost and completion time. The study suggests and recommends that, in order to bring the gaps on project risk management practices and improve its performance in future projects, the company should build a company culture that considers risk management practices, gives attention to risk management by assigning a risk management department at the head office level and a responsible team at the project, allocating fair resources both financially and man power and create awareness, give trainings,.. etc. Wed, 01 Jan 2025 00:00:00 GMT http://hdl.handle.net/123456789/8770 2025-01-01T00:00:00Z http://hdl.handle.net/123456789/8769 Title: ASSESSMENT OF DETERMINANTS OF QUALITY IMPROVEMENT PROJECT IMPLEMENTATION IN SELECTED HOSPITALS, ADDIS ABABA CITY ADMINISTRATION Authors: NEGA, WESSEN Abstract: This study examined the implementation status and determinants of quality improvement (QI) projects in selected hospitals within Addis Ababa City Administration. A descriptive crosssectional design was employed from November 20 to December 20, 2024, involving 104 participants from 10 hospitals selected through purposive sampling. Data were analyzed using SPSS Version 27 and MAXQDA 2020, with multivariate logistic regression identifying factors significantly associated with QI outcomes at a 95% confidence interval and a p-value threshold of 0.05. The findings revealed that adequacy of resources (AOR: 0.04, CI: 1.04–8.64, P=0.042), effective communication channels (AOR: 0.022, CI: 1.20–10.44), and a culture of continuous improvement (AOR: 0.003, CI: 1.69–12.72) were pivotal for successful implementation. Qualitative analysis highlighted barriers such as limited leadership engagement, resource constraints, and insufficient QI training. The study concludes that a multifaceted approach emphasizing strong leadership, organizational culture, resource adequacy, and staff capacity building is essential for sustaining QI initiatives. Targeted strategies, including leadership development programs and improved resource allocation, are recommended for policymakers and healthcare administrators to enhance QI efforts in healthcare settings.

The research employs a descriptive and explanatory research design, utilizing both quantitative and qualitative approaches. A structured survey questionnaire was distributed to employees, and interviews and direct observations were conducted to gather qualitative insights. Production records provided empirical data to assess defect rates, machine downtimes, and material waste. A stratified sampling technique was used to select employees from production and quality assurance departments, ensuring relevant expertise in the study. Findings indicate that high defect rates, inefficient machine utilization, and excessive material waste hinder the company’s compliance with international quality standards such as ISO 9001. Statistical analysis, including correlation and regression, reveals that organizational readiness, structured implementation frameworks, and employee engagement are key determinants of successful Lean and Six Sigma adoption. The study concludes that integrating these methodologies can significantly reduce production inefficiencies, enhance product consistency, and improve customer satisfaction, thereby strengthening Peniel’s market competitiveness. This research provides practical recommendations for manufacturing firms seeking continuous improvement through systematic quality and efficiency strategies.
