This paper consist of exploratory study to investigate the effect of virtual knowledge sharing of a project team in an organization via social networking site. Putting into consideration that Facebook is public domain, a social networking platform of a smaller scale known as Corporate Resource On-Demand & Community Sharing (CRODCS) is developed using open source software. This will allow the chosen platform to be tailor-suited and customized to any unit and project team preference. This paper employs social network analysis techniques using software package Agna 2.1 to map and analyze the patterns and flow of interactions critical to information and knowledge sharing of project discussions via CRODCS and gmail. The mapping of the knowledge flow was analyzed and compared in both platforms in order to study the effectiveness of knowledge sharing via social networking site. © 2010 IEEE.
