Duplication of data across systems in an organization is a problem because it wastes effort and leads to inconsistencies. Researchers have proposed several technical solutions but duplication still occurs in practice. In this paper we report on a case study of how and why duplication occurs in a large organization, and discuss generalizable lessons learned from this. Our case study research questions are why data gets duplicated, what the size of the negative effects of duplication is, and why existing solutions are not used. We frame our findings in terms of design rationale and explain them by providing a causal model. Our findings suggest that next to technological factors, organizational and project factors have a large effect on duplication. We discuss the implications of our findings for technical solutions in general.
