Towards a National Enterprise Architecture Framework in Iran

National Enterprise Architecture (EA) is regarded as a catalyst for achieving e-government goals and many countries have given priority to it in developing their e-government plans. Designing a national EA framework which fits the government’s specific needs facilitates EA planning and implementation for public agencies and boosts the chance of EA success. In this paper, we introduce Iran’s national EA framework (INEAF). The INEAF is designed in order to improve interoperability and deal with EA challenges in Iranian agencies.

The Quest for Underpinning Theory of Enterprise Architecture - General Systems Theory

Enterprise architecture originates from the 1980’s. It emerged among ICT practitioners to solve complex problems related to information systems. Currently EA is also utilised to solve business problems, although the focus is still in ICT and its alignment with business. EA can be defined as a description of the current and future states of the enterprise, and as a change between these states to meet stakeholder’s goals. Despite its popularity and 30 years of age, the literature review conducted on top information and management science journals revealed that EA is still lacking the sound theoretical foundation. In this conceptual paper, we propose General Systems Theory (GST) for underpinning theory of EA. GST allows us to see enterprises as systems of systems consisting of, for instance, social organisations, humans, information systems and computers. This explains why EA can be used to describe the enterprise and its components, and how to control them to execute the managed change. Implications to science and practice, and some directions for future research are also provided.

Enterprise Architecture beyond the Enterprise - Extended Enterprise Architecture Revisited

As the most enterprises are relying on relations to other enterprises, it is relevant to consider enterprise architecture for inter-organisational relations particularly those relations involving technology. This has been conceptualised as Extended Enterprise Architecture, and a systematic review of this discipline is the topic of this paper. This paper is taking a point of departure in general theories of business-to-business relationships along with inter-organisational information systems, interoperability and business ecosystems. The general theories are applied to the Extended Enterprise Architecture to emphasize paradoxes, problems and potentials in extending EA across organisational boundaries. The purpose of this paper is to review the concept of Extended Enterprise Architecture (EEA) theoretically and empirically to identify viability of Enterprise Architecture (EA) initiatives spanning across organisational boundaries. A case is presented of an enterprise engaging in technology-based business process integration that in turn is explicated as enterprise architecture initiatives with both more and less powerful partners. This paper underlines the necessity to be able to have EA spanning initiatives across multiple enterprises, but a range of problems is illuminated related to (lack of) precision, imbalance, heterogeneity, transformation, temporality, and (operational) maturity. The concept of EEA is seemingly vague, however this paper calls for a strengthen emphasis on redefining general architectural frameworks to embrace EEA in order to handle typical and modern forms of organisational designs relying on virtual and cross-company as cornerstones.

Generic EA Analysis Framework for the Definition and Automatic Execution of Analyses

Analysis is an essential part in the Enterprise Architecture Management lifecycle. An in-depth consideration of the architecture obtains its strengths and weaknesses. This provides a sound foundation for the future evolution of the architecture as well as for decision-making regarding new projects. Current literature provides a large number of different analysis approaches, targeting different goals and utilizing different techniques. To provide a common interface to analysis activities we studied the corresponding literature in previous research. Based on these results we develop a language for the definition of EA analyses as well as an execution environment for their evaluation. To cope with the high variety of meta models in the EA domain, the framework provides a uniform and tool independent access to analysis activities. Additionally it can be used to provide an EA analysis library, where the architect is able to select predefined analyses according to his specific requirements.

A Synthesis of Enterprise Architecture Effectiveness Constructs

Companies throughout the world use Enterprise Architecture (EA) because of benefits such as the alignment of business to Information Technology (IT), centralisation of decision making and cost reductions due to standardisation of business processes and business systems. Even though EA offers organisational benefits, EA projects are reported as being costly, time consuming and require tremendous effort. Companies therefore seek to ascertain ways to measure the effectiveness of EA implementation because of the money and time being spent on EA projects. EA Effectiveness refers to the degree in which EA helps to achieve the collective goals of the organisation and its measurement depends on a list of constructs that can be used to measure the effectiveness of EA implementation. Currently, there exist no comprehensive list of constructs that are suitable to measure the effectiveness of EA implementation. The paper reports on the results of a study that explored the development of a compreh ensive list of constructs suitable for measuring the effectiveness of EA implementation. The artefact developed in this research study is called Enterprise Architecture Effectiveness Constructs (EAEC). The EAEC consists of 6 constructs namely: - alignment

An AHP-based approach toward enterprise architecture analysis based on enterprise architecture quality attributes

Enterprise Architecture (EA) as a discipline that manages large amount of models and information about different aspects of the enterprise, can support decision making on enterprise-wide issues. In order to provide such support, EA information should be amenable to analysis of various utilities and quality attributes. In this regard, we have proposed the idea of characterizing and using enterprise architecture quality attributes. And this paper provides a quantitative AHP-based method toward expert-based EA analysis. Our method proposes a step-by-step process of assessing quality attribute achievement of different scenarios using AHP. By this method, most suitable EA scenarios are selected according to prioritized enterprise utilities and this selection has an important affect on decision making in enterprises. The proposed method also introduces a data structure that contains required information about quality attribute achievement of different EA scenarios in enterprises. The stored asset can be used for further decision making and progress assessment in future. Sensitivity analysis is also part of the process to identify sensitive points in the decision process. The applicability of the proposed method is demonstrated using a practical case study.

An investigation into applying UML to the Zachman framework

The Zachman framework is considered to be the most referenced framework for the purpose of enterprise architecture. It is commonplace to compare other frameworks with this basic one in order to show correctness and usability of those frameworks. However, this is more than a fashion, the Zachman framework is actually the best one. Despite of its popularity, the Zachman framework could be a challengeable one in practical situations because there are not enough well-known methods and tools covering all of its aspects. Three major challenges in using this framework, are discussed in this article. These challenges are lack of a methodology, a well-defined repository and a popular modeling notation. Focus of this article is on solving the last problem with the help of notations in UML (Unified Modeling Language) and UML Business Profile. At the first glance the topic seems to be already researched by others, but there are some major distinctions between this work and the others', which make it a unique one. Most of the other work tried to cover the framework using multiple class diagrams stereotyped in different ways. This work tries to cover the Zachman framework using all of the UML features, especially those, which are convenient in common modeling tools as well as ignoring unfamiliar symobls as it is used by some authors. A case study is used upon which we show how to apply the selected notation on a sample enterprise to develop cells in second and third rows of the framework. Models are tested to consider if they are supporting Zachman rules governing the framework. Furthermore, in order to see if they could be convincing enough, a statistical study is employed. Although results of these tests are relatively acceptable, the problem of inventing new modeling notations is mentioned as an open problem.

Benefits and challenges with Enterprise Architecture: a case study of the Norwegian Labour and Welfare Administration

Enterprise Architecture is seen as instrumental to drive the digital transformation in enterprises. It is also important to achieve the benefits from innovative new business models and technologies. Many organisations have therefore undertaken extensive efforts to implement Enterprise Architecture (EA). It is, however, a challenging task to implement enterprise architecture in an organisation. There is also very limited research on this issue related to the public sector. This study explores the implementation of enterprise architecture (EA) in the Norwegian Labour and Welfare Administration - NAV. While the study revealed that NAV had not defined any clear benefits, we found 12 perceived potential benefits. We also uncovered 16 challenges that impeded the EA implementation.

Smart Manufacturing Systems based on Cyber-physical Manufacturing Services (CPMS)

Future manufacturing is becoming “smart” - capable of agilely adapting to a wide variety of changing conditions. This requires production plants, supply chains and logistic systems to be flexible in design and reconfigurable “on the fly” to respond quickly to customer needs, production uncertainties, and market changes. Service-Oriented Architecture (SOA) provides a promising platform to achieve such manufacturing agility. It has proven effective for business process adaptation. When combined with the emerging Internet of Things (IoT) technology and the concept of cyber-physical production systems, it is expected to similarly revolutionize real-time manufacturing systems. This paper proposes a new concept of cyber-physical manufacturing services (CPMS) for service-oriented smart manufacturing systems. In addition, we propose a modeling framework that provides appropriate conceptual models for developing and describing CPMS and enabling their composition. Specifically, the modeling framework separates service provision models from service request models and proposes the use of standardized functional taxonomies and a reference ontology to facilitate the mediation between service requests and service consumptions. A 3D-printing use case serves as an example implementation of an SOA-based smart manufacturing system based on our proposed modeling framework.

The Cambridge Business Model Innovation Process

Organisations increasingly understand that meeting their sustainability ambitions does not only require new technologies, but innovation on the business model level. To facilitate the design of more sustainable business models, a range of new tools and techniques have been developed. While this resulted in the design of a wide range of promising business models, only very few are successfully implemented. The Cambridge Business Model Innovation Process is a framework developed to guide organisations’ business model innovation efforts and map the necessary activities and potential challenges. In this paper, we introduce the framework and present an exploratory attempt of applying it to a social start-up. The preliminary result of this experience led us to build a comprehensive research agenda that aims at developing tools and processes to help organisations in bridging the design-implementation gap in sustainable business model innovation.

Business model stress testing: A practical approach to test the robustness of a business model

Business models and business model innovation are increasingly gaining attention in practice as well as in academic literature. However, the robustness of business models (BM) is seldom tested vis-à-vis the fast and unpredictable changes in digital technologies, regulation and markets. The evaluation of the robustness of a BM raises several issues, such as how to describe the business model in a structured way, how to determine a relevant set of changes to test against, how to assess their impact on business model components, and how to use the results of the assessment to strengthen the business model. In this paper, we propose business model stress testing as a practical approach to evaluate the robustness of business model components. The method builds upon concepts from business model innovation and scenario planning. We illustrate our approach using a case example. Our approach enables testing individual business model components as well as the interrelation between components. The approach visualizes challenges and suggests ways to increase the robustness of BM. The stress testing approach is particularly useful in a stage of business model experimentation, i.e. if a company has to choose between alternative business models or still has to implement the business model. The underlying software tool is openly available for reuse and further development. The paper contributes to futures research literature by delivering the first method that allows to test the robustness of business models against future uncertainties.

The prioritization and categorization method (PCM) process evaluation at Ericsson: a case study

Purpose – The purpose of this paper is to demonstrate and evaluate the prioritization and categorization method (PCM), which facilitates the active participation of process stakeholders (managers, owners, customers) in process assessments. Stakeholders evaluate processes in terms of effectiveness, efficiency and relevance against certain contextual business and industry factors. This collective evaluation serves as a foundation for the management decision-making process regarding process improvement and redesign. Design/methodology/approach – The PCM is examined based on a case study at Ericsson. In total, 55 stakeholders, representing different organizational levels and functions, assessed eight core processes. Follow-up interviews and feedback after the evaluation sessions were collected for triangulation purpose. Findings – The PCM helps Ericsson evaluate its processes within business context and industry environments. The results show that, to realize seamless end-to-end processes in the eight assessed processes, Ericsson has to make a greater effort to improve its process structures, governance and culture for fulfilling the needs of future business. Ericsson Steering Group is satisfied with the insights provided and has decided to train more stakeholders to use PCM. Research limitations/implications – This research is based on a single case within a specific organizational setting. The results may not be necessary generalizable to other business and industry settings. Organizations need to configure PCM in consideration of their own processes and business contingencies to explore and fulfil their process improvement purposes. Originality/value – This paper presents a new context-aware, easy-to-use and holistic method for business process management (BPM), the PCM. The method requires the active engagement of stakeholders, it focusses on developing dynamic BPM capabilities and fully embeds organizational contingencies and contextual factors in the decision-making regarding BPM. This paper contributes a novel method to explorative BPM.

Understanding IT Alignment Paradox: A Three-Way Interaction of Intellectual Alignment, Social Alignment, and Environmental Dynamism

IT alignment is generally considered to be an enabler of firm performance. However, the previous literature has found that IT alignment has no or even a negative effect on firm performance, suggesting an alignment paradox. This study aims to address this paradox by focusing on the examination of how agility is enhanced or reduced. We consider the boundary conditions of environmental dynamism under which the effect of IT alignment varies. We then conduct a paired-matched survey of business and IT executives in 148 organizations to empirically examine the proposed research model. Our findings suggest that environmental dynamism has a negative moderating effect on the relationship between intellectual alignment and organizational agility, but a positive moderating effect on the relationship between social alignment and organizational agility. Furthermore, we find that in dynamic environments, intellectual alignment increases organizational agility only when it is complemented by social alignment.

Revisiting the Impact of Information Systems Architecture Complexity: A Complex Adaptive Systems Perspective

Organizations constantly adapt their Information Systems (IS) architecture to reflect changes in their environment. In general, such adaptations steadily increase the complexity of their IS architecture, thereby negatively impacting IS efficiency and IS flexibility. Based on a Complex Adaptive Systems (CAS) perspective, we present a more differentiated analysis of the impact of IS architecture complexity. We hypothesize the relation between IS architecture complexity on the one hand, and IS efficiency and IS flexibility on the other hand to be mediated by evolutionary and revolutionary IS change. Subsequently, we test our hypotheses through a partial least squares (PLS) approach to structural equation modelling (SEM) based on survey data from 185 respondents. We find that the direct negative impact of IS architecture complexity on IS efficiency and IS flexibility is no longer statistically relevant when also considering the mediating effects of revolutionary and evolutionary IS change.

Dynamic Ambidexterity: Exploiting Exploration for Business Success in the Digital Age

In the digital age, many firms find the pace of change in their industry is increasing. New competitors emerge from previously unrelated industries and innovative digital business models can quickly disrupt well-established market dynamics. Such jolts in the competitive landscape require existing players to be continually innovating while also “keeping the lights on” to maintain existing revenue streams. This paper reviews the IS literature on ambidexterity – the ability to simultaneously pursue strategies of resource exploration and exploitation – and advances a theoretical model for embedding innovative business models into existing organizational routines. It contributes to the literature by reconciling the structural and contextual views of ambidexterity through introducing a dynamic ambidexterity framework. This approach proposes ambidexterity as a dynamic capability which requires differing mechanisms in the initiation and implementation phases of innovation.

Analytics, Innovativeness, and Innovation Performance

Based on organizational information processing theory, this paper develops and tests a research model to deepen the understanding about the conditions under which the use of data analytics contributes to innovation performance. This paper suggests that firm innovativeness, as an organization cultural concept, should moderate the relationship between data analytics use and innovation performance. The results of a moderation analysis based on data from cross-sectional survey support this account. The findings indicate a significant inversely U-shaped effect of innovativeness on the relationship between data analytics use and innovation performance. The effect of data analytics use on innovation performance is strongest under medium levels of innovativeness but comparatively weaker when firms have a low or a high level of innovativeness. These insights contribute to the IS literature by clarifying the important role of firm cultural factors in shaping information needs and deployment of information processing capabilities.

An Explanatory Study on the Co-evolutionary Mechanisms of Business IT Alignment

Business IT Alignment is considered an enduring topic in academic and practitioners’ literature. The interest in the subject is justified by the link, demonstrated by several studies, between alignment and corporate performances. However, alignment research has not yet been translated into practices, theoretically demonstrated in literature and applied to companies. The interpretation of alignment as a function of independent factors and the underestimation of the complex nature of alignment process are considered key barriers in alignment achievement. The present study is based on a multi-case study analysis carried out in two companies that implemented alignment processes. We conceptualise alignment as a co-evolution process and derive four mechanisms and three types of parameters and explain their role in alignment implementation. The contribution is theoretical, since we analyse and describe mechanisms and factors that govern alignment, and for the practitioners, since knowledge of these mechanisms is precondition for an effective alignment implementation.

Conceptualization of an Abstract Language to Support Value Co-Creation

Companies willing to survive the numeric economy are forced to collaborate with each other in order to maximize their co-creation of value. This co-creation exists for many reasons: to sell and acquire information, goods and services, to optimize the quality of procedures, to improve security and privacy, etc. In this paper, we analyze and model value co-creation through three dimensions: the value's nature, the method of value creation, and the business object impacted by the value. By combining these dimensions, we afterwards suggest different types of co-creation schemas, and we propose an abstract language to communicate them. The latter is finally validated by applying the The Physics of Notations guidelines.

Organizational Learning Supported by Reference Architecture Models: Industry 4.0 Laboratory Study

The wave of the fourth industrial revolution (Industry 4.0) is bringing a new vision of the manufacturing industry. In manufacturing, one of the buzzwords of the moment is "Smart production". Smart production involves manufacturing equipment with many sensors that can generate and transmit large amounts of data. These data and information from manufacturing operations are however not shared in the organization. Therefore the organization is not using them to learn and improve their operations. To address this problem, the authors implemented in an Industry 4.0 laboratory an instance of an emerging technical standard specific for the manufacturing industry. Global manufacturing experts consider the Reference Architecture Model Industry 4.0 (RAMI4.0) as one of the corner stones for the implementation of Industry 4.0. The instantiation contributed to organizational learning in the laboratory by collecting and sharing up-to-date information concerning manufacturing equipment. This article discusses and generalizes the experience and outlines future research directions.

Enterprise Modeling for Business and IT Alignment – a Framework and Recommendations

Eliminating the gap between business and IT within an enterprise, i.e., solving the problem of Business and IT Alignment (BITA), requires an instrument for the multidimensional analysis of an enterprise. Enterprise Modeling (EM) is a practice that supports such analysis and therefore can be used to facilitate BITA. EM serves as a tool that can capture, visualize and analyze different aspects of enterprises. This article presents a framework that describes the role of EM in the context of BITA and presents recommendations in EM for BITA.

Research Perspective in Enterprise Architecture

The challenges of aligning IT with business triggered the attention towards Enterprise Architecture (EA). Despite the increase interest of academic scholars in EA, there is scarcity of studies that provide an up to date comprehensive research perspective view. The purpose of this study is to examine the research methodologies and theories utilized in EA studies from 2010 to 2016. The study employed Systematic Literature Review (SLR) as method to explore and analyze the literature of EA. The study revealed the research approaches and data collection methods utilized in EA. It shows that case study approach and interviews are the highly used compared to other research approaches and data collection instruments. Furthermore, it pointed out the low employment of theories in EA studies. The study is contributing to the body of knowledge by providing a foundation for novice researchers in the area of EA through detailed discussions of research methodologies and theories which are expected to support them in designing future studies.

Sustainability through Innovations Of Enterprise Architecture (EA) in Public Sector’s Management: Issues and Challenges

Innovations through Enterprise Architecture (EA) require a transformation in public sector’s management. EA has been identified as one of the prime initiatives towards public sector transformation. EA implementation is highly recommended to execute efficient and effective public service delivery. However, building upon several public sector agencies that had implemented these initiatives, EA implementation in Malaysian Public Sector (MPS) was reported as unfavourable. This study aims to identify related issues and challenges towards sustainability of EA implementation. A qualitative research approach was employed in this study. Semi structured interview was held involving five EA experts. From the analysis, six related issues such as (i) absence of the mandate from government to implement EA initiatives (ii) improper EA governance leading to difficulty in managing EA implementation; (iii) absence of EA tool to maintain EA document; (iv) lack of EA awareness (v) lack of EA readiness and (vi) limited knowledge and skills on EA among the team were discerned in sustaining EA practices. With regard to the practical implication, this paper can serve as reference in EA implementation in the public sector.

The Fatal Flaw of AI Implementation

There is no question that artificial intelligence (AI) is presenting huge opportunities for companies to automate business processes. However, as you prepare to insert machine learning applications into your business processes, I’d recommend that you not fantasize about how a computer that can win at Go or poker can surely help you win in the marketplace. A better reference point will be your experience implementing your enterprise resource planning (ERP) or another enterprise system. Yes, effective ERP implementations enhanced the competitiveness of many companies, but a greater number of companies found the experience more of a nightmare. The promised opportunity never came to fruition. Why am I raining on the AI parade? Because, as with enterprise systems, AI inserted into businesses drives value by improving processes through automation. But eventually, the outputs of most automated processes require people to do something. As most managers have learned the hard way, computers can process data just fine, but that processing isn’t worth much if people are feeding them bad data in the first place or don’t know what to do with information or analysis once it’s provided.

Industry 4.0 paradigm: The viewpoint of the small and medium enterprises

The pervasive diffusion of Information and Communication technologies (ICT) and automation technologies are the prerequisite for the preconized fourth industrial revolution: the Industry 4.0 (I4.0). Despite the economical efforts of several governments all over the world, still there are few companies, especially small and medium enterprises (SMEs), that adopt or intend to adopt in the near future I4.0 solutions. This work focus on key issues for implementing the I4.0 solutions in SMEs by using a specific case example as a test bench of an Italian small manufacturing company. Requirements and constraints derived from the field experience are generalised to provide a clear view of the profound potentialities and difficulties of the first industrial revolution announced instead of being historically recognised. A preliminary classification is then provided in view to start conceiving a library of Industry 4.0 formal patterns to identify the maturity of a SME for deploying Industry 4.0 concepts and technologies.
