Current challenges in design science research aim for consisting and detailed phases to guide design science researchers to manage projects in the information systems field. By having taken this challenge, we present a reference model, which serves as the foundation to structure information in construction of business process model artefacts in design science research. It contains activities responsible for literature review, collaboration with practitioners, and information-modelling. In this paper we demonstrate the collaboration with practitioners facet of the model to answer a question of how to construct a business process model artefact with practitioners from the field. The contribution of the paper is that application of the collaboration with practitioners activities in the context of design science supports the quality of design science artefacts, and provides design science researchers with choices of techniques.
