Abstract Today's enterprises are faced with an increasing rate of change in the economic environment. Underlying factors are the increased customization of products and services coupled with globalization and a more competitive market situation. Enterprises have to continuously adapt to these environmental changes by aligning their business, processes, applications, and technologies to the new requirements. One commonly accepted means to guide such adaptations is enterprise architecture (EA) management, which is a holistic and model-based approach to enterprise engineering aiming at aligning business and IT. Major tasks of the EA management function are the documentation of the current state of the EA, the design of desired future states, and the development of transformation plans guiding the evolution of the enterprise from the current to the desired future states. In order to guide the managed evolution of the EA, the EA management function has to interact with other enterprise level management processes and units within the organization and perhaps outside the organization. Thereby, it has to ensure that planned changes to the EA originating from other processes conform to the planned evolution of the EA. The EA management function therefore has to deal with various actors with diverse and possibly conflicting goals and backgrounds. Stakeholder theory describes stakeholder management processes that provide a systematic approach to this challenge. The aforementioned collaboration challenge between the various stakeholders of the EA can be mastered by an EA management function, which addresses the concerns of the different stakeholders during architecture development. The Enterprise Architecture Management Pattern Catalog (EAMPC) provides a collection of EA methods to address typical concerns. Thereby, it supports the EA management function in dealing with a multitude of stakeholders and their concerns. Nevertheless, the concept of stakeholders is missing in the EAMPC. The objective of this thesis is to close the aforementioned gap. Therefore, a stakeholder management approach is developed based on an analysis of the state-of-the-art of stakeholder management in literature and a series of expert interviews. The literature analysis provides stakeholder management concepts, as well as stakeholder roles and their concerns. Furthermore , stakeholder roles and their concerns are derived from the expert interviews. Then, an exemplary role set is built from the expert interviews and complemented with the role information discovered in the literature analysis. Theses stakeholder roles are then related to the …
