- The strategic role of IT and its significance throughout the organization in-creases in environments characterized by com¬plex¬ity, variety and change. Hence IT management must deal with uncertainties and with different, conflicting and ever changing demands. In this sense Enterprise Architecture is playing an increasingly important role in improving IT management practice. This paper presents architectural design principles that strive to create and maintain alignment in a dynamic and uncertain business environment. Two crucial architectural aspects will be highlighted: (1) the delineation of the information systems, (2) the choice of interoperability principle. A case from Swedish Industry is used to demonstrate the application of the principles. In the paper we argue that the choice of principles has an significant impact on operational as well as strategic alignment. The larger, heterogeneous, and dynamic the business are, the more crucial are the issues of information systems delineation and interoperability

Operational and Structural Business IT Alignment

Tidskriftsartikel (refereegranskat)abstract
- In recent years, Enterprise Architecture has gradually emerged as the preeminent means to change and transform large organizations. By employing Architectural Principles, organizations strive to master the complexity inherent in business processes and IT system and their harmonious alignment. Unfortunately, very rarely has the coevolutionary and emergent nature of alignment been taken into consideration in IS research. Even if different approaches focus on business IT alignment, most of them have a tendency to focus on alignment as a state or an outcome. In this paper we argue that a dynamic approach is necessary in order to achieve business IT alignment in a long-term perspective. Furthermore we demonstrate that the choice of architectural principles has an impact on the ability to achieve and maintain operational as well as structural alignment. A case study is used as a basis for the analysis. The conclusion is that an Enterprise-centric architecture can create freedom of action for dynamic operational alignment, and that Business-oriented IT management can keep the IS Architecture aligned with the Business Architecture in a long term perspective.

The Impact of Enterprise Architecture Principles on the Management of IT Investments

Tidskriftsartikel (refereegranskat)abstract
- The strategic role of IT and its significance throughout the organization in¬creases com¬plexity, variety, and the need of change. Hence IT management must deal with uncertainties derived from different, conflicting and ever changing demands. In this sense Enterprise Architecture is playing an increasingly important role in improving IT management practice. If contemporary organizations do not succeed in managing architectural issues, there is a clear risk that considerable resources will be invested without achieving desirable ef¬fects. This paper investigates how Enterprise Architecture Principles impact on the management of IT-investments in the context of large organizations. The purpose of the paper is to provide a deeper insight of the relationship between Enterprise Architecture and management of IT Investments throughout the elucidation of two significant types of principles: Delineation (differentiation) principles and Interoperability (integration) principles. Our conclusion is that the choice of architectural principles has a main impact both on alignment between information systems and business demands and on the management of IT investments. This impact concerns at least four aspects: (1) The responsibility for IT investments (2) Time to value (3) Long term alignment, (4) Coordination of investments in information systems with changes in business processes.

Architectural principles for alignment within the context of agile enterprises

Konferensbidrag (refereegranskat)abstract
- During the last few decades, new perspec¬tives have evolved, both on business and IT development, where orga¬ni¬zations are viewed as dynamic and complex information environments. While many entrenched organizations experience varying degrees of crises, we can note a rapid growth of new, flexible and dynamic organizations that have found new ways to compete and cooperate. In times of increasing heterogeneity and turbulence in the business environment, the concept of agility has become a new guiding paradigm for the management of change and development of enterprises. Agile business requires agile information systems and this have consequences on how the systems should be delineated and integrated. This paper presents architectural principles that strive to create and maintain alignment in enterprise architecture in a dynamic and uncertain business environment. In the paper we discuss the following two crucial aspects in the context of an agile enterprise: (1) the delineation of the involved information systems and their ability to change and operate independently of each other, (2) the choice of interoperability principle and its impact on agility. A case from Swedish Health Care is used to demonstrate the application of alternative sets of architectural principles. Through the use of the case we discuss the above two aspects as well as the impact of the principles on agility and alignment. In the paper we argue that the choice of principles for delineation and interoperability has a significant impact on business agility and on long term alignment. Strategies that are efficient and offers agility enough in a limited area of the organization may not be suitable in large complex organizations. The larger, heterogeneous, and dynamic the business and its environment are, the more crucial are the issues of information systems delineation and interoperability. The conclusion is that the choice of a suitable architectural principle is a main condition for aligning information systems to business demands and to create agility. Different principles for systems delineation and interoperability should therefore be analyzed and evaluated in an agility perspective before choice of alternative. If the wrong principles are chosen, there is a considerable risk for misalignment and expensive consequences.

Konferensbidrag (refereegranskat)abstract
- In times of increasing uncertainty and turbulence in the business environment, the concept of agility has become a new guiding principle for the change and development of enterprises. Agile business requires agile information systems and this have consequences on how the systems should interoperate. This paper describes and analyzes the impact of information systems interoperability strategies on business agility. Three interoperability strategies are identified; unification, intersection and interlinking. Cases from Swedish Health Care are used to demonstrate the application of the strategies. The conclusion is that the choice of interoperability strategy has significant impact on business agility and should therefore be analyzed and evaluated carefully. If the wrong strategy is chosen, there is a considerable risk for misalignment and expensive consequences. The challenge is to create architectural solutions for interoperability that are in harmony with the demands of the business, both in a short term and a long term perspective.

Konferensbidrag (refereegranskat)abstract
- Enterprise Architecture (EA) has emerged as the preeminent means to change and transform large organizations. By employing architectural principles, organizations strive to master the complexity inherent in business processes and information system and their alignment. Despite the fact that Business-IT alignment has been a top concern for practitioners and researchers for years, the emergent nature of alignment in EA has rarely been taken into consideration. Even if different approaches focus on business IT alignment, most of them have a tendency to focus on alignment as a state or a process by focusing on strategy or organizational issues. Moreover, very few existing EA Frameworks give clear guidance on how to design and manage these alignment issues. In this paper we argue that the choice of architectural principles has an impact on the ability to achieve and maintain sustainable EA alignment in a dynamic business context. A case study is used as a basis for the analysis.
