How should we communicate evaluation work in design science research (DSR)? A case study based on our industry collaboration research project encountered this challenge after finding limited guidance on a structure to effectively communicate DSR evaluation work. We propose a logic model as a consistent reporting structure to communicate DSR evaluation by presenting a unified view of inputs, outputs, and immediate and long-term outcomes. The case study is based on an IT service organisation where a novel research artefact to conduct IT service process assessments was implemented. We present this case study as a real-life exemplar for an experimental design involving the use of a logic model to communicate DSR evaluation work. This case study provides a source of qualitative evaluation data to explore and subsequently analyse how the application of a simple logic model might provide the much needed structure to communicate critical evaluation activities in a DSR project.
