According to Nonaka and Takeuchi (1995), individuals create knowledge through social interaction. Inherently, knowledge resides within individuals and more specifically, in the employees who create, recognize, archive, access, and apply knowledge in carrying out their tasks (Nonaka & Konno, 1998). To spread knowledge between employees and also from repositories and databases inside the organi- zations, the knowledge sharing process and behaviors need to be improved. For the purpose of sharing knowledge across the time and location, virtual collab- orative technologies need to be implemented. The propagation of collaborative technologies facilitated the rapid progression of virtual communities. Many people participate in vir- tual collaborative networks for investigating knowledge to solve problems at work. However, if people do not have rich knowledge about subjects, the virtual networks will have kind of a limited value (Chiu, Hsu, & Wang, 2006). Socio-Behavioral Factors in Virtual Knowledge Sharing: Theory of Reasoned Action and Theory of Planned Behavior Perspective Farkhondeh Hassandoust, Multimedia University, Malaysia Mehdy Farzaneh Kazerouni, Multimedia University, Malaysia Vimala Perumal, Multimedia University, Malaysia ABSTRACT Recently, there has been extraordinary propagation in the number of virtual teams for knowledge sharing; however, fnding out what affects team member’s behavior is important. This paper integrates the Theory of Reasoned Action (TRA) and the Theory of Planned Behavior (TPB) to construct a model for investigating the socio-behavioral factors behind virtual knowledge sharing. The results of previous studies in this domain paved the path for these factors to be categorized in three conceptual components based on TPB: attitude, subjective norm and perceived behavioral control.
