Understanding collaborative work practices represents a critical factor in and a necessary fundament for the development of effective Computer Supported Collaborative Work (CSCW) systems. In today?s economies, collaborative work is increasingly knowledge intensive, distributed and workers are more and more conceptualized as knowledge workers. This yields to the question how especially distributed knowledge work practices can be identified and visualized as a basis for the development of CSCW systems. This contribution 1) investigates how a traditional knowledge work analysis approach can be adapted for application in distributed settings and 2) reports on the preliminary findings of an explorative case study.
