The necessary knowledge transfer and communication between project members is identified as a relevant issue in information systems development (ISD). Nevertheless, the impact of linguistic communication on ISD and requirements specification in its processual nature is still an open issue. In our research, we claim that effectiveness of ISD depends on the ability to manage how people deal with language in practice and reach a shared understanding. We propose the concept of language quality as a suitable means for analyzing the emergence of concise and meaningful requirements in ISD. By applying the thereby developed language quality dimensions on a real project, we were able to obtain practice-grounded propositions for practitioners to consider and for researchers to further evaluate the consequences of different actions on the interaction and communication processes for this particular field.
