Conference Paper
Low-Code Development Platforms (LCDPs) enable non-information technology (IT) personnel to develop applications and workflows independently of the IT department. Consequently, these digital platforms help to overcome the growing need for software development. However, science and practice warn of several barriers that slow down or hinder the usage...
Conference Paper
Market research institutes forecast a growing relevance of Low-Code Development Platforms (LCDPs) for organizations. Moreover, the rising number of scientific publications in recent years shows the increasing interest of the academic community. However, an overview of current research focuses and fruitful future research topics is missing. This pap...
Conference Paper
Business units are increasingly able to introduce information technology (IT) into their business processes. Thereby, they implement Shadow IT (SIT) to create flexible and innovative IT solutions. However, the individual implementation of SIT leads to unwanted data and functional redundancies and as a result to inefficiencies and reduced automation...

Zusammenfassung Kleine und mittelständische Unternehmen (KMU) sind bekannt für ihre Innovationskraft und bilden das Rückgrat der deutschen Wirtschaft. Wie Studien zeigen sind sie in Bezug auf Compliance-Maßnahmen im Vergleich zu kapitalmarktorientierten Unternehmen jedoch im Rückstand. Eine gesonderte Betrachtung der IT-Compliance erfolgt dabei in...
Article
Full-text available
Business units are increasingly able to fuel the transformation that digitalization demands of organizations. Thereby, they can implement Shadow IT (SIT) without involving a central IT department to create flexible and innovative solutions. Self-reinforcing effects lead to an intertwinement of SIT with the organization. As a result, high complexiti...

[https://tu-dresden.de/bu/wirtschaft/isih/ressourcen/dateien/paper/IJITBAG-Kopper-Fuerstenau-et-al-2018-Shadow-IT-and-Business-Managed.pdf] Research on Shadow IT is facing a conceptual dilemma in cases where previously “covert” systems developed by business entities are integrated in the organizational IT management.

Research on Shadow IT is facing a conceptual dilemma in cases where previously "covert" systems developed by business entities (individual users, business workgroups, or business units) are integrated in the organizational IT management. These systems become visible, are therefore not "in the shadows" anymore, and subsequently do not fit to existin...
Conference Paper
Shadow information technology systems (SITS) coexist with formal enterprise systems in organisations. SITS pose risks but also increase flexibility of business units. Practice shows that SITS emerge, despite that Enterprise Architecture Management (EAM) aims at controling all IT systems in an organization. Studies acknowledge this problem in genera...
Article
In several organizations, business workgroups autonomously implement information technology (IT) outside the purview of the IT department. Shadow IT, evolving as a type of workaround from nontransparent and unapproved end-user computing (EUC), is a term used to refer to this phenomenon, which challenges norms relative to IT controllability. This re...
Article
Das Thema Schatten-IT hat erst in den letzten Jahren in Wissenschaft und Praxis erheblich an Bedeutung gewonnen.1 Unter dem Begriff Schatten-IT werden dabei Systeme verstanden, welche die Fachbereiche in Eigenregie beschaffen oder erstellen und die nicht in das IT-Servicemanagement des Unternehmens eingebunden sind.2 Das Thema Schatten-IT ist dabei...

The IT unit is not the only provider of information technology (IT) used in business processes. Aiming for increased performance, many business workgroups autonomously implement IT resources not covered by their organizational IT service management. This is called shadow IT. Risks and inefficiencies associated with this phenomenon challenge organiz...

Article
Full-text available
ERP systems integrate a major part of all business processes and organizations include them in their IT service management. Besides these formal systems, there are additional systems that are rather stand-alone and not included in the IT management tasks. These so-called ‘shadow systems’ also support business processes but hinder a high enterprise...

In diesem Beitrag wird gezeigt, welche Einsatzszenarien Schatten-BI hat, welche Chancen und Risiken mit ihr verbunden sind und wie sie zielgerichtet gesteuert werden kann.
Conference Paper

Der Begriff Schatten-IT beschreibt Systeme, die außerhalb des Verantwortungsbereiches der IT durch die Fachabteilung eigenständig entwickelt und betrieben werden. Obwohl dieses Phänomen weit verbreitet ist, blieb diese Schatten-IT in Wissenschaft und in Praxis lange unbeachtet. Seit einiger Zeit ist eine verstärkte Auseinandersetzung mit dem Phänom...

Article
Als »Schatten-IT« werden geschäftsprozessunterstützende IT-Lösungen bezeichnet, die Fachabteilungen eigenständig einsetzen und die nicht in das IT-Servicemanagement der Organisation eingebunden sind. Cloud Computing erleichtert diesen Einsatz durch eine ausgeprägte Prozessorientierung und den vereinfachten Zugang zu IT-Lösungen. Die dadurch potenzi...

Shadow IT describes the supplement of “official” IT by several, autonomous developed IT systems, processes and organizational units, which are located in the business departments. These systems are generally not known, supported and accepted by the official IT department. From a company's, IT governance and IT management's perspective it is necessa...

Projektarbeit durchdringt alle Unternehmensbereiche. Strategische Initiativen ziehen eine Vielzahl von Projekten nach sich. Die Anzahl von Projekten nimmt auch als Antwort auf eine zunehmende Umweltdynamik zu. Als Folge beansprucht Projektarbeit wesentliche finanzielle Ressourcen: Ein Projektkostenanteil von mehr als 10% der Gesamtkosten ist in zah...

Die Beurteilung der Wasserqualität nach ökonomischen Kriterien bedingt eine grundlegende Untersuchung des Produktionsprozesses der Trinkwasserherstellung. Die Wasseraufbereitung wird daher einer produktionswirtschaftlichen Analyse nach dem Konzept von Hahn und Laßmann unterzogen. Dabei wird unter anderem gezeigt, dass es sich bei der Wasseraufberei...
