The internet provides a media-rich navigational environment where people interact with computer systems. This interactive relationship between humans and computers can be explored from a socio-technical philosophy. Thus, investigating individual behaviors toward new information technologies based on their experiences with the internet technology in general, and content management in particular emerged as an alternative stream of research. Since users' behaviors are heavily influenced by web sites usability, this study is aimed at exploring multidimensionalty in usability constructs of a content management system. The findings indicate that multidimensional model - at least- with two upper constructs exist in usability. This finding supports the socio-technical perspective in usability in that content presentation and architectural design were perceived as separate constructs by participants.
