Ulrich Frank (born 1958) is a German Business informatician and Professor of Business informatics at the University of Duisburg-Essen, known for his work on the state of the art in information systems research^[1] and the development of the Multi-Perspective Enterprise Modeling (MEMO) meta modelling framework.^[2]

After studying business administration at the University of Cologne, Frank in 1988 received his doctorate from the University of Mannheim with a dissertation, entitled "Expertensysteme – Neue Automatisierungspotentiale im Büro- und Verwaltungsbereich" (Expert systems - New Potentials for automation in office and administration area).^[3]

Frank wrote his habilitation in 1993 at the University of Marburg, and was appointed Professor of computer science at the University of Koblenz-Landau in 1994. In 2004 Frank moved to the University of Duisburg-Essen, where he was appointed Professor of computer science and business enterprise modeling.^[4]

The focus of Frank's work is on multi-perspective enterprise modeling. He has developed and researched the (meta-) method Multi-Perspective Enterprise Modeling (MEMO), which propagates a scientific approach of enterprise modeling and adds value in the discourse of integrative modeling, across the functional areas of business functions.

Frank published several books and articles.^[5] Books:
