Enterprise modelling framework for dynamic and complex business environment: socio-technical systems perspective

The modern business environment is characterised by dynamism and ambiguity. The causes include global economic change, rapid change requirements, shortened development life cycles and the increasing complexity of information technology and information systems (IT/IS). However, enterprises have been seen as socio-technical systems. The dynamic complex business environment cannot be understood without intensive modelling and simulation. Nevertheless, there is no single description of reality, which has been seen as relative to its context and point of view. Human perception is considered an important determinant for the subjectivist view of reality. Many scholars working in the socio-technical systems and enterprise modelling domains have conceived the holistic sociotechnical systems analysis and design possible using a limited number of procedural and modelling approaches. For instance, the ETHICS and Human-centred design approaches of socio-technical analysis and design, goal-oriented and process-oriented modelling of enterprise modelling perspectives, and the Zachman and DoDAF enterprise architecture frameworks all have limitations that can be improved upon, which have been significantly explained in this thesis.

Controlling kooperativer Wertschöpfungsnetzwerke von IT-Dienstleistern

Im Zentrum der Dissertation steht die Entwicklung einer Controllingkonzeption für die kooperative Erstellung von IT-Dienstleistungen in Wertschöpfungsnetzwerken. Dabei werden zunächst Spezifika der kooperativen Leistungserstellung und dem Controllingobjekt IT-Dienstleistung erörtert. Wichtige Aspekte sind hierbei die Berücksichtigung verschiedener Kategorien von IT-Dienstleistungen, unterschiedliche Betrachtungsebenen der interorganisationalen Leistungserstellung sowie die Heterogenität der Lebenszyklusphasen eines Wertschöpfungsnetzwerks. Auf Basis dieser Rahmenbedingungen werden konkrete Ziele, Aufgaben und organisationale Anforderungen an das Controlling kooperativer Wertschöpfungsnetzwerke von IT-Dienstleistern identifiziert. Anschließend werden hierzu geeignete Instrumente der Planung, Steuerung und Kontrolle präsentiert. Die praktische Anwendbarkeit des vorgeschlagenen Instrumentensets wird anhand eines fiktiven Fallbeispiels demonstriert. This dissertation presents a concept for networks of IT service providers from a management accounting perspective. Specific attributes of cooperative networks, such as perspectives of interorganizational processes and the life cycle of value networks, and the production of IT services, such as IT service categories, constitute fundamental factors for the development of this concept. Besides, these factors determine goals, tasks and organizational aspects of the management accounting concept. These issues are used to identify appropriate instruments for planning, governing and controlling IT service networks. The practical applicability of these instruments is demonstrated with the help of a fictitious case study
