With service-oriented architectures and the process-centric development of application systems, we are experiencing the beginning of a reorientation in how information technology is used in the global economy as well as in our private lives. Language-critical Organization Theory has thus become a discipline in research and teaching. Because of the global nature of these endeavors, it is important to look for a common basis for possible cooperation partners in this field. The necessary efforts are enormous and can only be managed successfully by working together. Looking at how the philosophy of science has developed throughout the twentieth century seems to imply that a) the primarily American analytic philosophy of science paired with b) the methodical constructivism of predominantly German origin (Erlangen and Constance) could form this common basis. In this paper, both philosophies, well-grounded in the works of Wittgenstein (1889-1951) and Frege (1848-1925), will form the foundation (Lorenzen, 1994) substantiating practical development in the field of e.g. service-oriented architecture. The common foundation will also disclose what people must be able to do or, respectively, what they must know (understand) if they want to work successfully in the IT-industry in the future.
