The Internet of Things (IoT) has become a crucial topic in research and industry over recent years. Enterprises often fail to create business value from IoT technology because they have difficulties defining organizational integration. Model-driven Development (MDD) is considered an effective technique for IoT application development. We argue that methods for MDD should comprise the organizational as well as the system development and integration. This paper aims to provide an overview of the current state of research on MDD of IoT applications. For this purpose, we conducted a structured literature review (SLR). A research gap was identified as no specific research could be found on MDD of IoT applications with a focus on organizational and system aspects. We also derived requirements from an industrial use case. The main contributions of this paper are (a) requirements from medium-sized enterprises (SMEs) to methodical and technical IoT development support derived from a use case, (b) the results of a systematic literature analysis in this field, and (c) an initial structure for the methodical support and initial architecture for the accompanying tool support.
