Handledare: Julia Kaidalova Examinator: Vladimir Tarasov Omfattning: 30 hp (D-nivå) Datum: September 16, 2013 Postadress: Besöksadress: T el ef on: Box 1026 Gj uteri gatan 5 036-10 10 00 (vx) 551 11 Jönköping Abstract Abstract The most important characteristic of enterprise architecture (EA) is that, it provides a holistic view of the enterprise. EA needs to consider about different aspects, views and viewpoints in an enterprise in order to make an enterprise more understandable and communicable to achieve organization goals and objectives. To do this matter EA needs to use different techniques or enterprise modeling methods to achieve different results of EA (documents/artifacts, models, goals/benefits). But many organization for building EA, use their own description techniques and conventions instead of using existing techniques or existing EMMs. They might use one technique which is not appropriate for modeling all aspects of EA. Our purpose is to discover the usefulness of EMMs in the process of construction EA to provide expected results of EA. We investigated about different EMMs to see its usefulness in producing which expected EA result. In order to increase the accuracy of the final results we investigated about different EMMs with respect to important EA aspects. To perform this study we have gone through a survey to validate EA important aspects and essential results of EA. Results of our study conducted based on both using literature review for studying about the usefulness of different EMMs and the results of our survey (EA aspects and results of EA). The results of this research show that Business, Organization, Technical, Information and Decision Making are five important aspects of EA; different EMMs can be used to produce several results of EA. We used table to illustrate the results of the study for each EA aspect separately. Our analysis revealed that the Decision Making and Information aspects of EA could get more help from EMMs compare to the other aspects, since the main focus of some of these methods such as GERAM, GRAI and GIM are mainly accumulated in these two aspects. i Acknowledgements Acknowledgements We would like to thank our supervisor Julia Kaidalova and coordinator Vladimir Tarasov whose advices, support and their facilitator role from the very beginning to final phase contributed us to develop this thesis.

  • Enterprise Architecture As Explanatory Information Systems Theory for Understanding Small- and Medium-Sized Enterprise Growth
    sustainability Article Enterprise Architecture as Explanatory Information Systems Theory for Understanding Small- and Medium-Sized Enterprise Growth Aurona Gerber 1,2,* , Pierre le Roux 1,3 and Alta van der Merwe 1 1 Department of Informatics, University of Pretoria, 0083 Pretoria, South Africa; [email protected] (P.R.); [email protected] (A.v.d.M.) 2 CAIR, Center for Artificial Intelligence Research, 0083 Pretoria, South Africa 3 Moyo, 0157 Centurion, South Africa * Correspondence: [email protected] Received: 31 July 2020; Accepted: 7 October 2020; Published: 15 October 2020 Abstract: Understanding and explaining small- and medium-sized enterprise (SME) growth is important for sustainability from multiple perspectives. Research indicates that SMEs comprise more than 80% of most economies, and their cumulative impact on sustainability considerations is far from trivial. In addition, for sustainability concerns to be prioritized, an SME has to be successful over time. In most developing countries, SMEs play a major role in solving socio-economic challenges. SMEs are an active research topic within the information systems (IS) discipline, often within the enterprise architecture (EA) domain. EA fundamentally adopts a systems perspective to describe the essential elements of a socio-technical organization and their relationships to each other and to the environment in order to understand complexity and manage change. However, despite rapid adoption originally, EA research and practice often fails to deliver on expectations. In some circles, EA became synonymous with projects that are over-budget, over-time and costly without the expected return on investment. In this paper, we argue that EA remains indispensable for understanding and explaining enterprises and that we fundamentally need to revisit some of the applications of EA.

  • Study of Implementing Zachman Framework for Modeling Information Systems for Manufacturing Enterprises Aggregate Planning
    Proceedings of the 2011 International Conference on Industrial Engineering and Operations Management Kuala Lumpur, Malaysia, January 22 – 24, 2011 Study of Implementing Zachman Framework for Modeling Information Systems for Manufacturing Enterprises Aggregate Planning Radwan, A., and Majid Aarabi Department of Manufacturing and Industrial Engineering, Faculty of Mechanical Engineering, Universiti Teknologi Malaysia, 81310 Skudai, Johor, MALAYSIA [email protected] , [email protected] Abstract Response time on orders of customers is becoming a critical issue to achieve a competitive advantage. A major problem is a lack of strategic perspective of information systems. A need for adequate tools and methodologies to model the system structure and to define integrated requirements is a must for the manufacturing enterprises. This paper presents a study of implementing Zachman Framework ZF to model information systems for aggregate planning activities within the manufacturing enterprises. An Information System for simulating the aggregate planning activities such as evaluating the various planes for determining the production rate, inventory levels, subcontracting and the required human resources is modeled. This is assumed to provide control over the order processes and reporting the orders status online. It is assumed that the customer can have access to the system to follow up with his order progressing status. Managers would have control on orders transactions, and workshop floor supervisors could monitor and control the orders processing online. Some artifacts are introduced to ZF to enhance its capability for modeling of information systems for Aggregate Planning in Manufacturing Enterprises. Keywords: Manufacturing Information Systems, Zachman Framework, Enterprise architecture, Aggregate planning, Modeling. 1. Introduction Nowadays, the enterprises encounter with numerous amount of data.

  • Business Reference Model of the Local Self-Government That Uses Process Management
    Business reference model of the local self-government that uses process management Markéta Zimmermannová Department of Information Technologies, Faculty of Informatics and Statistics, University of Economics, Prague, Czech Republic [email protected] Abstract. The objective of this paper is a brief introduction in the doctoral thesis of the author. The content of the thesis is the design of the structure for efficient management of the public administration. The author explores the options, how to combine the Enterprise Architecture elements with the business process management methodology MMABP. The output is the design of the optimal structure of the public administration office at the business level – Business reference model. Keywords: enterprise architecture, business process model, business reference model, public administration. 1 Introduction The subject of the doctoral thesis regards the Business process management and the Enterprise Architecture and the options of their application in the local self-government in the Czech Republic. In comparison with the private sector, the local self-government (and public administration in general) has a much broader set of competences. This also generates much complicated requirements on the process, functional, organizational and technological structure of the local self-government bodies. Implementation of such a structure can however be simplified by a certain form of business process standardization and by using of the Enterprise Architecture elements. The doctoral thesis therefore explores and proposes the options for usage of the process management (represented by MMABP methodology) based on the broader exploration of the very basis that the local self-government stands on and its combination with the Enterprise Architecture.

  • Examining Capabilities As Architecture
    September 2013 BPTrends ▪ Examining Capabilities as Architecture Examining Capabilities as Architecture Ralph Whittle Introduction This Article is a direct response to one written by Mike Rosen titled, “Are Capabilities Architecture?” [1] published in February 2013 by BPTrends It offers a different and contrasting point of view on accepting capability modeling and mapping as “architecture.” Business Architecture (BA) approaches and methods, while still evolving, have at least reached a point of maturity where the enterprise can fairly assess how it will develop and advance this initiative. As with any emerging field, a variety of approaches and methods will develop and enjoy success. From an historical perspective, consider the number of Business Process Management (BPM), Enterprise Architecture (EA) and Service-Oriented Architecture (SOA) approaches that have matured over the years. And no doubt, the same will eventually occur with the Business Architecture over the next few years. However, just as with the BPM, EA and SOA some different and contrasting points of view will find their way into the various Business Architecture approaches, techniques and methods. Today, at least two different and contrasting organizing principles are considered for Business Architecture. One is “capability centric” and the other is “process centric.” This article advocates and supports the “process centric” organizing principle, specifically using a value stream which is an end-to-end collection of activities that creates a result for a “customer,” who may be the ultimate customer or an internal “end user” of the value stream. The value stream has a clear goal: to satisfy (or, better, to delight) the customer.[2] This is a well known term, familiar in Six Sigma, Lean Manufacturing and BPM approaches.

Will iams The 1990s have seen many large-scale efforts to transform companies into more agile and efficient global enterprises. An important lesson from the efforts in computer-integrated manufacturing and other businesses has been that enterprises-like any other system - need to be properly designed and that methods to do this should become widely available and publicised. Architectures for Enterprise Integration describes the latest methods to guide enterprises and consultants, managers and technical personnel through a complete life-cycle of enterprise development. This book is based on the findings of the IFIP/IFAC Task Force and presents a state-of-the-art review of enterprise architecture, including: • analysis and comparison of the three major architectural frameworks and methodologies; • identification of the strengths and weaknesses of each methodology to enable users to select the approach which best suits their needs; • a road map for the development of more complete methodologies by using existing ones. This book is essential reading for all practising engineers and researchers in manufacturing and engineering management and will be of special interest to those involved in CIM and enterprise modelling and integration. p .

    Preprint version of an article published as: Business Process Management Journal, Year: 2005, Volume: 11, Issue: 5, Page: 517-531, ISSN: 1463-7154, DOI: 10.1108/14637150510619867 © Emerald Group Publishing Limited http://www.emeraldinsight.com/bpmj.htm Towards a workflow-based integration architecture for business networking Diogo M. R. Ferreira INESC Porto, Portugal J. J. Pinto Ferreira Faculty of Engineering, University of Porto, Portugal Keywords BPM, enterprise integration architectures, workflow technology, e-business Abstract The Internet is the underlying network infrastructure that will allow enterprises to create new business structures and to reconfigure existing ones. This trend, which is known as business networking, requires enterprises to be able to integrate and coordinate business processes that extend across autonomous business partners. Traditionally, the problem of integration has been addressed by the field of Enterprise Integration, which underlines the importance of Workflow Management as a tool for business process integration. In the context of business networking, most of the principles of Enterprise Integration and Workflow Management are still useful but, definitely, a new kind of architecture is required. This paper proposes a decentralized inter-enterprise workflow solution, paving the way towards an integration architecture that will allow enterprises to automate their business relationships and to develop arbitrary business networks. 1. Introduction The Internet fosters new business possibilities that will make enterprises reengineer their systems and reorganize themselves. As a globally connected and widely accessible network infrastructure, the Internet provides unprecedented access to potential business partners. In an increasingly connected world, it becomes easier to find business partners that can perform some of the work better, faster and cheaper.

  • A Modelling Language for User Oriented Enterprise Modelling
    3e Conférence Francophone de Modélisation et SIMulation "Conception, Analyse et Gestion des Systèmes Industriels" MOSIM'01 - du 25 au 27 avril 2001 - Troyes(France) A MODELLING LANGUAGE FOR USER ORIENTED ENTERPRISE MODELLING Martin ZELM Kurt KOSANKE CIMOSA Association e.V. CIMOSA Association e.V. Gehenbühlstr. 18 A, D-70499 Stuttgart Stockholmer Str. 7, D-71034 Böblingen Mél . [email protected] Mél . [email protected] Abstract: Enterprise modelling provides the means to structure and decompose the enterprise system into less complex parts and to describe functionality and behaviour of the operation or any part thereof. The relevant enterprise knowl- edge can be captured, shared and managed through process models. Process models describe both the functionality and the flow of control in the enterprise and identify all the needed and produced information. However, the user should employ a modelling language consisting of modelling constructs relevant for the representa- tion of his business. Constructs, which provide means for easy information capturing and are represented by easy to understand graphical symbols or icons. Both, common modelling construct types and their representation by icons will make the modelling process more effective and efficient and also improve the human understanding of enterprise mod- els. The latter is especially important for the upcoming e-business to business and virtual enterprise type operations. Only with increased efforts in harmonisation and standardisation, will the envisaged improvements be realised. Starting from the CIMOSA reference architecture the paper proposes structuring of user oriented modelling construct types and type hierarchies and presents an overview of construct icon types for graphical representation used in differ- ent modelling tools.
