Enterprise Architecture for The Sensing Enterprise: A Research Framework

Internet of Things (IoT) will change many things, open up opportunities and enabling something that was not possible before. IoT provides sensing capability so that enterprise has better global context awareness. This is the Sensing Enterprise, an enterprise that obtains multidimensional information from physical or virtual objects in a connected environment. This sensing capability is expected to increase the capacity and capability of the enterprise in responding to sustainability challenges. This paper proposes a research framework as an alternative guide for researchers to produce various artifacts or theories to realize The Sensing Enterprise for sustainability achievement. The method used in developing the framework is modification/adaptation of transdisciplinary research model and information system research model. This framework has three main area consist of scientific base, enterprise architecture research process and sustainability achievement.

Enterprise architects as digital transformers

Enterprise architecture is critical to digital transformation. It can stop new business strategies from being realized or enable their realization.

The industrial internet of things (IIoT): An analysis framework

Historically, Industrial Automation and Control Systems (IACS) were largely isolated from conventional digital networks such as enterprise ICT environments. Where connectivity was required, a zoned architecture was adopted, with firewalls and/or demilitarized zones used to protect the core control system components. The adoption and deployment of Internet of Things (IoT) technologies is leading to architectural changes to IACS, including greater connectivity to industrial systems. This paper reviews what is meant by Industrial IoT (IIoT) and relationships to concepts such as cyber-physical systems and Industry 4.0. The paper develops a definition of IIoT and analyses related partial IoT taxonomies. It develops an analysis framework for IIoT that can be used to enumerate and characterise IIoT devices when studying system architectures and analysing security threats and vulnerabilities. The paper concludes by identifying some gaps in the literature.

Enterprise Thinking for Self-aware Systems

The paper aims to provide high-level guidance for architects of cyber-physical enterprises such that the nature of interactions within it as a system can be largely self-determined based on system self awareness and dynamic self-configuration, and a set of foundational guiding principles, rather than being pre-defined by an external designer or architect. The paper investigates the suitability of typical development life cycles and architectural challenges in the context of dynamic cyber-physical systems intending to utilize the power of the Internet of Things, and then goes on to define desired attributes of such systems, which need to guide suitable core architectural choices. Application of the findings is exemplified through a case study, followed by synthesis of issues and implications for further research.

IT Governance in Scaling Agile Frameworks

Dynamic business environments call for companies’ organizational agility as being able to sense the changes in competitive environments and respond accordingly. A flexible IT environment facilitates this aim but contrasts with the structuration of IT organization through IT governance. We analyze how scaling agile frameworks as blueprints for agile IT organizations solve the contrast between structuration embedded in IT governance and agility. We see converging business and IT in structure and strategy as facilitator for resolving this conflict. In detail, we compare eight scaling agile frameworks on how IT governance is covered, how IT governance decisions are made and whether business IT convergence is achieved. We conclude that IT governance is still predominantly top down decision-making and focuses on traditional business IT alignment instead of business IT convergence. With our analysis, we provide a comprehensive base for organizations to choose from when approaching their specific agility challenges.

A measurement model to analyze the effect of agile enterprise architecture on geographically distributed agile development

Efficient and effective communication (active communication) among stakeholders is thought to be central to agile development. However, in geographically distributed agile development (GDAD) environments, it can be difficult to achieve active communication among distributed teams due to challenges such as differences in proximity and time. To date, there is little empirical evidence about how active communication can be established to enhance GDAD performance. To address this knowledge gap, we develop and evaluate a measurement model to quantitatively analyze the impact of agile enterprise architecture (AEA) on GDAD communication and GDAD performance. The measurement model was developed and evaluated through developing the AEA driven GDAD model and associated measurement model based on the extensive literature review, model pre-testing, pilot testing, item screening, and empirical evaluation through a web-based quantitative questionnaire that contained 26 different weighted questions related to the model constructs (AEA, GDAD active communication, and GDAD performance). The measurement model evaluation resulted in validated research model and 26 measures: 7 formative items for AEA, 5 reflective items for communication efficiency, 4 reflective items for communication effectiveness, 2 reflective items for each on-time and on-budget completion, and 3 reflective items for each software functionality and quality. The results indicate the appropriateness and applicability of the proposed measurement model to quantitatively analyze the impact of AEA on GDAD communication and performance.

An integrated conceptual model for information system security risk management supported by enterprise architecture management

Risk management is today a major steering tool for any organisation wanting to deal with information system (IS) security. However, IS security risk management (ISSRM) remains a difficult process to establish and maintain, mainly in a context of multi-regulations with complex and inter-connected IS. We claim that a connection with enterprise architecture management (EAM) contributes to deal with these issues. A first step towards a better integration of both domains is to define an integrated EAM-ISSRM conceptual model. This paper is about the elaboration and validation of this model. To do so, we improve an existing ISSRM domain model, i.e. a conceptual model depicting the domain of ISSRM, with the concepts of EAM. The validation of the EAM-ISSRM integrated model is then performed with the help of a validation group assessing the utility and usability of the model.

The Digital Diamond Framework: An Enterprise Architecture Framework for the Digital Age

Enterprise architecture (EA) frameworks of the past have attempted to support the cohesive and comprehensive modeling and documentation of the enterprise, often with a focus on business and information technology (IT). However, the digitalization of enterprises and the complexity of IT have outgrown these matrix box-like frameworks. This paper proposes a digital, holistic, and sustainable EA framework, called the Digital Diamond Framework, to support digitized enterprises in aligning the real EA state with the desired state.

Coming of Age Digitally: Learning, Leadership and Legacy

As businesses mature digitally, they stand apart from rivals. A survey by MIT SMR and Deloitte found digitally mature companies are better at developing digital leaders, pushing decision-making deeper, and responding faster to the marketplace, and are more likely to experiment.

Using Structural Coupling Approach for Defining and Maintaining Identity of an Educational Institution. Experience Report

This paper presents an ongoing study on defining and maintaining organizational identity of an institution of higher education, such as a department or school. The theoretical background used in the study is the concept of structural coupling that comes from biological cybernetics. The study concerns the authors own department. The paper presents proposals of to which elements of the environment such an institution is structurally coupled and how the identity maintenance is arranged. The paper provides examples of how maintaining identity works or not works in practice based on reflections on the authors' experience of working in their own department. It also shows that maintaining identity may requires changes in different components of the socio-technical system, e.g. methods, people, technology.
