This paper intends to highlight the significance of ‘High Performance Work Practices (HPWPs)’ on employee performance and knowledge capabilities from the perspective of knowledge-sharing environment and shared work practices. By taking into account the underlying challenges governing the creation of ‘High Performance Knowledge Sharing Culture (HPKSC)’, this paper argues how specific set of Organizational factors (HPWPs) and Knowledge-Sharing factors can be applied and practiced in conjunction to result in HPKSC i.e. a flourishing Knowledge-sharing culture focused on delivering superior firm performance. Accordingly, a conceptual framework is developed using above set of factors that serves as a basis for deriving HPKSC, aimed at achieving firm performance and innovation capabilities.
