<b>Impact of Knowledge Sharing on Project Success in Public Sector Projects in Kabul, Afghanistan</b>

This research analyzes how knowledge sharing affects public sector project success within the Afghan public sector in Kabul. The practice of sharing knowledge between stakeholders represents a fundamental element for project success because it involves exchanging information and expertise and past experiences. Public sector projects in developing nations along with conflict-affected areas such as Kabul experience scarce empirical research about knowledge sharing effects on project success. The research fills this knowledge gap through an investigation of knowledge sharing practices (independent variable) and their impact on project success (dependent variable) in the special socio-political environment of Kabul. The research uses a quantitative approach that distributes surveys to 250 public sector project employees working in Kabul. The analysis of data through regression methods determined the relationship between project success and knowledge sharing practices. The research findings demonstrate that knowledge sharing contributes positively to project success since it accounts for 77% of the variance in project success outcomes. The research findings demonstrate how effective knowledge sharing helps public sector projects in Kabul overcome resource limitations and political unrest and institutional deficiencies that commonly affect development projects in the area. The study adds empirical evidence to existing literature about the vital importance of knowledge sharing in public sector project success in developing countries. Through practical examples the study provides guidance to both public sector managers and Kabul policymakers who should build a collaborative environment with trust-based learning practices to achieve better project results. The study confirms the necessity of solving communication limitations and incentive deficits to enhance project achievement in public sectors throughout Kabul and other comparable regions.
