Resilience and enterprise architecture in SMEs
Considering that SMEs need to embrace the drivers of resilience and that a well defined and readily available Enterprise Architecture (EA) supports enterprise integration by enabling the common view of business processes, data and systems across the enterprise and its partners, we can say that EA is one of the tracks making resilience predictable and it should support and collaborate with other resilience tracks. However, the EA frameworks do not give relevance to the activities that contribute most to business resilience, so this paper aims to clarify the dimensions and the activities related to the development of an EA and the touching points with other enterprise wide processes in order to guarantee that resilience requirements are met in SMEs. For this I propose an approach of ecological adaptation, and four architectures: business, organizational, information, and technological, although this paper only presents the Business and Organizational Architectures.

Enterprise Architecture for Digital Transformation
Digital transformation requires an altogether new institutional logic and effective response at a requisite organizational level. Sensing and seizing fleeting market opportunities and reconfiguring the business in line with the shifting value proposition requires increasingly specialized resources, more dynamic capabilities, and in built resilience in the face of change. While Enterprise Architecture (EA) has been suggested to facilitate enterprise transformation, the focus has traditionally been on process standardization and integration rather than on continuous adaptation to the changing business and technological landscape. For EA to have a desired impact, more adaptive conceptualizations of EA that address the requirements of the new digital environment are called for. In this conceptual paper, we explore the implications of digital transformation on enterprise architecture. In particular, we note that existing approaches to EA address integration and coherence within a single organization but typically fall short in the face of complexities pertaining to digital ecosystems. We suggest a vertical typology of organizational capabilities and postulate that today's digital environment increasingly requires adaptive capabilities that transcend the traditional notion of dynamic capabilities. We then investigate how EA can help build flexibility and resilience in the organization.

Towards the Next Generation Service Oriented Enterprise Architecture
Emerging business models such as digital ecosystems involving collaborative innovation, participatory decision making and flexible organizational structures are set to significantly affect inter and intra enterprise structure and functionality. This has seen the appearance of increasingly complex Service oriented Architecture (SOA) scenarios featuring various partnership levels, increased resilience and adaptation to tougher compliance regulations, more seamless integration with process layers, etc. This complexity has brought about the need to broaden the SOA paradigm, so as to include business, infrastructure and multi layering, resulting in an evolved concept known as Service Oriented Enterprise Architecture (SOEA) This paper aims to describe the way new business and technology paradigms continue to affect the new SOEA approach and how the inherently holistic Enterprise Architecture (EA) frameworks and related practices can support the emerging complex dynamic, multi layered and value chained service based scenario.

Cyber Resilience: Seven Steps for Institutional Survival
Abstract No enterprise will ever be 100% secure. There are just too many threats. This article presents seven practical steps to achieving cyber resilience. Cyber resilience is not a traditional defensive stance. It requires a change in the way organizations approach security of its information and communication technology (ICT) asset base. Cyber resilience is integrated into the "bones" of the organization and requires the organization to develop a well defined, explicit architecture of controls to ensure cyber resiliency. The controls assure provable protection of critical ICT assets and their various interdependencies from every form of electronic, human and physical threat; inside and outside the enterprise's eco system. Cyber resilient architectures make attacks less likely to succeed, minimize the consequences when they do, increase the work factor cost and uncertainty for the adversary, and possibly act as a deterrent against future attacks. Cyber resilience is enforced as an organizational condition rather than a deployed set of explicit countermeasures. This goal requires that a robust set of concrete controls are embedded in the enterprise architecture. Effective implementation of a cyber resilient enterprise architecture requires strategic vision. It also requires day to day engagement across the enterprise to ensure that the controls that enable cyber resilience are effective.

Selected Topics on Business Informatics: Editorial Introduction to Issue 19 of CSIMQ
The objective of this thematic issue was twofold. The first it was to present selected research results of the 17th International Conference on Perspectives in Business Informatics Research (BIR2018) in Stockholm, Sweden, in September 24 26, 2018. The conference created a productive forum for researchers and practitioners on the specific topic Business Resilience, with the intention of exploring organizational and information system resilience in congruence. Top papers were selected by the Program Chairs Prof. Janis Grabis and Prof. Jelena Zdravkovic to submit extended versions for a possible publication to this thematic issue. The second objective was to consider external candidate submissions for bringing attention to recent research in the Business Informatics discipline and thus make this issue even more actual. Five articles were selected that report on research in ecosystem architecture management, strategic coopetition, deriving enterprise architecture model from data, hierarchic viewpoints in control compliance assessments, and operationalizing enterprise IT architecture.

Assessing Resilience in Enterprise Architecture: A Systematic Review
This review paper aims to explore state of the art research and scientific literature about Enterprise Architecture (EA) resilience. Based on a systematic literature review, 850 articles have been subjected to evaluation for relevance. Based on the findings in 58 selected papers, we conclude that the field of EA resilience is still in its infancy. We identified several definitions and classified six types of resilience measures, based on information type (qualitative/quantitative) the source of the disruption (internal/external) and the duration of the resilience (short term/long term) Based on the review, we found 19 metrics that are candidates for EA practitioners to consider for the design of measurement and assessment methods for EA resilience. In addition, we identified relevant research from Information Systems sub domains and other sciences that can be incorporated to create a holistic view on EA resilience. Based on published definitions of resilience in the selected papers, we propose a definition of the concept of EA resilience. This definition is validated using expert opinion and creates a starting point for reasoning about EA resilience and future research.

Contribution Title Enterprise Architecture Approach to Resilience of Government Data Centre Infrastructure
We can observe a paradigm shift with respect to government data centres. Due to the complexity of such a data centre system, new types of quality attributes should be used, such as resilience, trustworthiness, and sustainability. This paper offers a general approach to the transformation of government data centres for different enterprise levels from a resilience point of view. It presents an enterprise architecture approach to the development of a federal data centre, considering resilience as a quality attribute. The approach is supported by using ArchiMate: an enterprise architecture modelling language. Resilience is considered from various perspectives: business, application, infrastructure and physical. An agnostic solution is proposed which is based on architecture and design patterns.

Total Exposure Management: Enterprise Risk Management, Organizational Resilience and Change Management
Two decades passed since the pioneering work embodied in the AS/NZS 4360 Risk Management Standard, and in spite of the refinements offered by the subsequent COSO and ISO 31000 frameworks the concept of enterprise wide risk management remains an elusive target. Business organizations continue to hope to transform the historically cost containment focused risk management efforts into a true source of competitive advantage, but obstacles remain. Key among those impediments is the continued fragmentation of organizational adversity abetment efforts, where known risks focused risk management, unknown threats oriented organizational resilience and self imposed transformations minded change management continue to function as three stand alone research disciplines and organizational practice areas. The research described here proposes that combining those three now distinct disciplines into a single, Total Exposure Management framework, with the goal of moving toward transforming the practice of broadly defined organization wide risk management into a source of competitive advantage.

The role of organizational culture for grounding, management, guidance and effectiveness of enterprise architecture principles
Enterprise architecture management (EAM) has become a widely acknowledged approach for guiding the continuous change of increasingly complex organizations. While methods and models for describing and analyzing enterprise architectures (EA) have been extensively discussed, principles guiding an EA's design and evolution are hardly covered in existing research. The paper at hand therefore analyzes the mechanisms of EA principles (EAP) that is EAP grounding, EAP management, and EAP guidance and their effects on EA consistency and EAM utility. Specifically we aim at understanding the role of organizational culture for the mechanisms and effects of EAP. Based on empirical data we find that all relations describing EAP mechanisms and their effects are significantly moderated by organizational culture. Based on our findings we give recommendations on how to deal with selected design decisions when introducing and developing EA principles in an organization.

Organizational Subcultures and Enterprise Architecture Effectiveness: Findings from a Case Study at a European Airport Company
This paper studies how organizational subcultures influence the effectiveness of the enterprise architecture (EA) function. It provides findings from a case study in a European airport company. We find specific subcultural differences that can lower EA effectiveness. In addition, we discover that not only subcultural differences but also subcultural similarity can reduce EA effectiveness. For instance, the preference for working isolated of some business departments results in a lack of communication between those departments, which lowers EA effectiveness. Also, our data suggest that the subcultural influence is indirect. We identify, amongst others, communication defects as an important intermediary variable.
