The success of wikis on Internet has led the organizations to introduce wikis within corporate settings for multiple purpose. However, despite the popularity of wikis in public and subsequently in the corporate environment, an empirical investigation of their benefits within organizations is still lacking. This study performs an empirical investigation with 177 corporate wiki end-users to evaluate their performance after wiki use. Enterprise wiki end-user performance is evaluated by measuring user's efficiency, effectiveness and capacity development. PROCESS macro in SPSS is used to empirically test specific indirect effects via mediation. The findings suggest that the collaboration quality, information quality, and system quality of enterprise wikis help its users in increased efficiency, effectiveness, and their capacity development.
