    Contradictions and Interventions in Health IS
    (Business & Information Systems Engineering: Vol. 63, No. 6, 2021) Weeger, Andy; Wagner, Heinz-Theo; Gewald, Heiko; Weitzel, Tim
    The study analyzes data collected in two case studies in the healthcare industry, which is characterized by a variety of social and technical elements forming an activity system where all elements interact with each other. The findings indicate that many problems emerging during the implementation of a health information system can be traced back to contradictions between elements of the activity systems that are created or amplified by the new IS. The authors find that some contradictions are latent and become salient when introducing a new IS, while other contradictions are (unintentionally) newly created. Also, the study shows that contradictions are more complex than hitherto assumed and often concern more than two elements of a healthcare activity system. In a similar vein, effective interventions geared toward countering these contradictions are found to account for additional complexity while not always achieving their goal. Drawing on activity theory, the authors develop a framework to coherently synthesize the findings. The study can help increase the understanding of the IS’s role within an activity system and help guide IS implementation projects aimed at avoiding unintended consequences.

    Die Bedeutung des Alignment von IT und Fachressourcen in Finanzprozessen Eine empirische Untersuchung
    (Wirtschaftsinformatik: Vol. 48, No. 5, 2006) Beimborn, Daniel; Franke, Jochen; Gomber, Peter; Wagner, Heinz-Theo; Weitzel, Tim
    KernpunkteIn diesem Beitrag wird im Rahmen einer empirischen Studie mit den 1.000 größten deutschen Banken gezeigt, wie im Zusammenspiel von Fach-und IT-Ressourcen und dem Alignment beider Bereiche die Geschäftsprozessleistung positiv beeinflusst werden kann. Es zeigt sich insbesondere, dasssowohl IT-Ressourcen als auch fachliche Ressourcen einen positiven Einfluss auf die Prozessleistung aufweisenAlignment als eigenständiger Faktor einen singulären Wertbeitrag aufweistauch eine sehr gute IT Schwächen auf Seiten der Fachabteilungen nicht kompensieren kann und ein Geschäftswertbeitrag durch IT somit auch maßgeblich von Faktoren abhängt, die häufig nicht im Einflussbereich der IT liegen.AbstractImportance of the Alignment of IT and Business Resources in Financial Processes — An Empirical Study How do firms realize business value from deploying IT in business processes? Based on the Resource-based View and insights from recent literature on IT/business alignment, we argue that actual usage and the alignment of IT and business units are important prerequisites for a superior performance of IT-intensive business processes. In this paper, a causal model on the joint impact of IT usage, IT/business alignment and business resources on business process performance is proposed and empirically validated using data from Germany’s 1.000 largest banks.It turns out that the perceived performance of the focal business process, as predicted in the theoretical model, strongly depends on IT/business alignment. The empirical analysis also shows that business resources have a large impact and that even a superior IT cannot compensate business resource deficiencies. The results thereby provide support for important propositions of the literature on alignment from a process perspective and contribute to common knowledge that the business value of IT should not be assessed without evaluating and controlling for business resources as a complementary factor.
