    DESERV IT: A Method for Devolving Service Tasks in IT Services
    (Business & Information Systems Engineering: Vol. 63, No. 4, 2021) Baer, Florian; Sandkuhl, Kurt; Leyer, Michael; Lantow, Birger
    Nowadays, IT operations devolve many tasks in IT services to internal customers (i.e., IT self-service). The rationale for this service task devolvement is often to reduce the IT personnel’s workload. However, prior research has shown that IT operations often fail to achieve this goal. Existing methods for modeling and analyzing services fall short of supporting service providers in identifying and specifying service tasks suitable to be devolved to (internal) customers. This paper presents, therefore, the first method for devolving service tasks in IT services (DESERV IT). DESERV IT is a compound of four method components encompassing a joint meta-model, a visual notation for modeling IT services, and procedural recommendations. The DESERV IT meta-model extends the meta-model of service blueprinting by means of concepts required to analyze service task devolvement. DESERV IT is evaluated in four evaluation episodes. The results of the evaluation episodes show that DESERV IT is perceived as effective, useful, complete, and generalizable by experts in the IT service management and enterprise architecture discipline. This paper contributes to enterprise modeling by demonstrating the feasibility of DESERV IT in an example case and describing DESERV IT’s evolution during the evaluation episodes. DESERV IT supports practitioners (e.g., request fulfillment managers) in modeling and analyzing IT services.

    DevOps—Welcome to the Jungle
    (HMD Praxis der Wirtschaftsinformatik: Vol. 56, No. 2, 2019) König, Georgia; Kugel, René
    Der vorliegende Artikel beschäftigt sich zentral mit dem Thema DevOps. Dafür werden die Ursprünge, Entstehung und Entwicklung der DevOps-Bewegung beleuchtet. Es wird diskutiert, warum der Begriff nicht konkret definiert werden kann und welche Auswirkungen dies mit sich bringt. Weiterhin werden ausgewählte Grundlagenprinzipien erläutert und verschiedene Strategien aufgezeigt mittels welchen DevOps in den ersten Schritten in IT-Unternehmen eingeführt werden kann. Zusätzlich wird das Konzept von NoOps eingeführt, welches als Weiterentwicklung von DevOps betrachtet werden kann. Auf der Basis dieser Konzepte wird argumentiert wie sich der Beruf des Developers, als auch der Operations-Fachkraft verändert und mit welchen neuen Herausforderungen diese konfrontiert werden. This article talks about the topic of DevOps. The origins, emergence and further expansion over time of the DevOps movement will get highlighted. A discussion takes place, why the term cannot be specifically defined and which effects this entails. The underlying core principles are explained and a number of strategies are shown on how IT companies can implement initial steps for a DevOps adaptation. In addition, the concept of NoOps is presented which can be regarded as a further development of DevOps. On the basis of the two presented concepts it is argued how the profession of developer, as well as operation experts might change and with which new challenges they will be confronted.
