The success of such endeavors depends on the ability of consumers to discriminate between offered services and choose those best fulfilling the requirements, though. To facilitate the assessment of services against functional requirements, this article proposes the Business-Oriented Service Description Language (BoSDL). It consists of: (1) a meta-model with rules to describe the business logic, that is, the functionality of a software service from a business-oriented perspective; (2) a textual presentation format based on English natural language; (3) a graphical notation based on the UML. Findings from a controlled experiment indicate that, compared to the state of the art, the information provided with the BoSDL enhances the ability of consumers to judge if software services satisfy existing functional requirements.Design scienceService descriptionService selectionSoftware as a serviceText/Journal Article10.1007/s12599-018-0554-01867-0202
