On the one hand, available CWE platforms are used insufficiently. On the other hand, they do not yet support collaboration in a completely adequate way. This paper illustrates the current state of CWE practice by way of a sample company, its internal and external collaboration processes and the services used. Improvements provided by major vendors in the domain of commercial CWE platforms and the current techniques of Web-2.0 are analysed with regard to the concept of context- based communities that ought to be applied within any CWE efforts according to this paper.enText/Conference Paper1617-5468
