This paper proposes a way of describing IT-services that follows the paradigm of a “service dominant logic”. Authors therefore transfer “service dominant logic” to the realm of IT and propose guidelines to create customer oriented service descriptions. An excerpt of a prototype description serves as an example, how the technical, inside view on IT-services can be translated into a customer-oriented outside view. The results of their research process are design rules to describe customer focused IT services, that are tested through applying it in a description prototype. The most important achievement of this prototype is that due to the rules the whole document is focused on customer needs and not on technical inputs.
