Social networking sites (SNSs) are available at workplace and have created an environment for workers to share information and socialize with others. The study aims at revealing the links among the functionality of SNS attributes, hierarchical value map (HVM) and task performance, by using means-end chain (MEC) approach. In order to examine the links between the internal company SNS attributes and consequences, as well as the values of each which the employees regard as important. Data was gathered for a MEC analysis by interviewing 30 employees in a company. Laddering interviews identify employees’ perceptions of six attributes, nine consequences, and six values associated with the internal company SNS adoption. The results show that the functionalities of online learning, questions and responses, and knowledge sharing are useful for knowledge collaboration and task performance. Finally, we also analyze other items linked to attributes layer, consequences layer and values layer to provide insights for constructing effective mechanisms in working contexts.
