Web-based communication and collaboration is a significant trend in modern enterprises. However, communication as well as collaboration still makes use of various platforms like email, instant-messaging, or wikis. Google introduced Google Wave to solve the disadvantages in usage caused by the combination of multiple technologies. The contribution of this paper is an analysis comparing Wave to other kinds of communication and collaboration with regard to its application as an enterprise 2.0 tool. Based on this, an integration prototype is implemented, which reveals the essential effort of interconnecting Google Wave to an Enterprise Content Management System.
