    Innovationsorientiertes IT-Management – Eine Fallstudie zur DevOps-Umsetzung bei T‑Systems MMS
    (HMD Praxis der Wirtschaftsinformatik: Vol. 54, No. 2, 2017) Alt, Rainer; Auth, Gunnar; Kögler, Christoph
    DevOps ist ein junges Konzept, das aufbauend auf agilen Ansätzen die Entwicklung von – häufig innovativen – IT-Lösungen mit deren Betrieb verbindet. Nachdem DevOps bislang eher einer Philosophie denn einer ausgearbeiteten Methode gleicht, ist bis zur Verfügbarkeit von Vorgehensmodellen, Templates und durchgängigen Werkzeugen jedes Unternehmen gefordert, eine individuelle Interpretation zu entwickeln. Das Beispiel der T‑Systems MMS zeigt, dass sich zwar zahlreiche vorhandene Entwicklungswerkzeuge für DevOps verwenden lassen, der DevOps-Ansatz aber über eine toolgetriebene Automatisierung hinausgeht. Im Ergebnis bildet DevOps ein neues Instrumentarium, um die Agilität und Innovationsorientierung des IT-Managements zu steigern.AbstractDevOps is a young concept, which is based on agile approaches and links the development of IT solutions, which are often innovative in nature, with their operation. Since DevOps is rather a philosophy than an elaborated method, each company is required to develop an individual adaptation until standardized process models, templates and comprehensive tools become available. The case of the T‑Systems MMS illustrates that although many existing development tools may be used for DevOps, the DevOps approach reaches beyond a tool-driven automation. As a result, DevOps needs to be conceived as a new means for increasing agility and innovation orientation of IT management.

    ITIL als Common-Practice-Referenzmodell für das IT-Service-Management — Formale Beurteilung und Implikationen für die Praxis
    (Wirtschaftsinformatik: Vol. 46, No. 5, 2004) Hochstein, Axel; Zarnekow, Rüdiger; Brenner, Walter
    In the course of increasing customer orientation in the IT sector, IT service management becomes more important. Especially the de facto standard ITIL receives attention of IT management at present. Deficits of the ITIL reference model are often ignored, benefits are only assumed and a lot of misunderstandings exist. Uncertainties, unfulfilled expectations and problems during the accomplishment of ITIL projects are the result. In this context the paper deals with a critical analysis of the ITIL reference model. It fulfils a formal evaluation of the model on the basis of established criteria. On the basis of this evaluation implications for IT management are derived. Findings are derived from four case studies as well as an in-depth analysis of the ITIL documentation itself.

    Untersuchung der Lebenszykluskosten von IT-Anwendungen
    (Wirtschaftsinformatik: Vol. 46, No. 3, 2004) Zarnekow, Rüdiger; Brenner, Walter; Scheeg, Jochen
    IT management focuses on planning and developing new IT solutions. The importance of production (operation, support, maintenance) and further development of existing solutions is often neglected, although these tasks are responsible for the majority of today’s IT costs. The paper introduces a life cycle model for IT application systems and presents the results of a survey of the life cycle costs of 30 IT application systems. Within the survey, the distribution of costs over the application life cycle was recorded and evaluated. The results show the central importance of recurring costs for production and further development. For a production time of 5 years these costs amounted to 79% of all life cycle costs, whereas only 21% of the costs were incurred during the planning and initial development stages.
