  "description": "<p>This study examined the effect of leadership styles on project performance, focusing on the role of teamwork as a mediator in the Goba-Berbere-Dellomena construction and design project. The full-range leadership development model served as the research&#39;s guidance. A mixed-method approach was used in the research, with both quantitative and qualitative data being collected and analyzed. There were 142 replies to the study, which used a sample size of 155 and a population of 260. Purposive sampling as well as stratified random sampling was used in the sample design. Descriptive analysis, inferential OF correlation analysis, regression analysis, mediation analysis using SPSS version 26, Sobel test, and structural equation modeling by SPSS-AMOS were all used to analyze the data. The validity and reliability by Cronbach&#39;s Alpha coefficient of 0.967 were checked. The results showed that transformational leadership (with mean of 3.73) was the most common type shown by project managers, with transactional leadership(with mean of 3.62) following in second while laissez-faire the least(with mean of 2.96). The project was operating under budget and on schedule, according to objective performance measures of Earned Value Management (EVM) and generally favorable feedback. Strong cooperation, communication, and a happy work atmosphere were all noted as positive aspects of teamwork practices, while there was still space for development in terms of team commitment. Correlation analysis showed strong positive relationships between transformational leadership (r = 0.80, p &lt; 0.01) and transactional leadership (r = 0.71, p &lt; 0.01) with project performance, while laissez-faire leadership had a weak relationship (r = 0.298, p &lt; 0.05). Regression analysis further supported these findings, demonstrating significant impacts of transformational (&beta; = 0.601, p &lt; 0.001) and transactional leadership (&beta; = 0.241, p &lt; 0.001) on project performance, whereas laissez-faire leadership did not have a significant impact (&beta; = 0.071, p = 0.166). SEM analysis indicated significant positive indirect impacts of both transformational (indirect effect = 0.649, p &lt; 0.001), and transactional leadership (indirect effect = 0.393, p &lt; 0.01) on project performance through the mediation of teamwork. The Sobel test confirmed the mediation effect of teamwork for transformational (Sobel test statistic = 9.89, p &lt; 0.001) and transactional leadership (Sobel test statistic = 3.54, p &lt; 0.001). Although laissez-faire leadership showed a significant indirect effect on project performance through teamwork (indirect effect = 0.173, p &lt; 0.05), its total effect was not statistically significant (total effect = 0.141, p &gt; 0.05). It was also discovered that the relationship between transformational, transactional, and project performance leadership styles is mediated by teamwork. By offering actual data on the crucial role that project manager leadership plays in promoting project performance and the mediating role that teamwork plays, the study adds to the body of literature. A balanced strategy that utilizes both transformational and transactional leadership characteristics is advisable for project managers to implement, as are practical suggestions like encouraging good collaboration among project staff. These realizations have the potential to raise the effectiveness of Ethiopian construction projects and improve project management procedures.<br>\n&nbsp;</p>",
