Iacob (Assistent-promotor) English Summary This thesis proposes a methodology for creating business models, evaluating them, and relating them to enterprise architecture. The methodology consists of several steps, leading from an organization’s current situation to a target situation, via business models and enterprise architecture. The problems with Business-IT Alignment Currently, increasing amounts of businesses rely on IT systems to do their business. aligning existing IT systems with business objectives. A consensus exists among However, success rates of IT implementations projects are low. Difficulties exist in researchers and practitioners alike that business-IT alignment (BITA) is necessary to improve business performance. Typical symptoms of lack of BITA include: • People cannot use the systems effectively. • • Systems cannot be changed easily and quickly to adapt to new situations. Changes in systems often do not consider the financial impacts. Difficulties also exist with technological innovations. Most difficulties are not caused by technical issues. Lack of consideration for financial and organisational aspects is a cause aspects of innovations. Projects are often more expensive than planned due to changing for projects not surviving after the pilot phase. A lack of attention is paid to financial requirements. Projects are often more expensive than planned because demands are not well known. Therefore, we have a problem to build and adapt IT systems to changing business needs. This thesis attempts to combine two partial solutions to this problem, Enterprise Architecture (EA) and Business Modelling (BM). A partial solution: Enterprise Architecture the organisation, from different viewpoints and according to the needs of different Enterprise Architecture comprises a collection of simplified representations of stakeholders. A coherent description of enterprise architecture provides insight, enables communication among stakeholders, and guides complicated change processes. ArchiMate provides a language to create such descriptions in a precise and formal way. strategy, and use of ArchiMate is limited to expert users. While Enterprise Architecture helps to manage change, it includes insufficient business Another partial solution: Business Modelling In the basis, business models are used to describe businesses and explore possibilities for future development. Business modelling is intuitive to use by managers, consultants, V and entrepreneurs alike. The business model concept is a young and emerging field several competing schools of thought exist, and progress is limited because of a lack of of research. The state in which this field finds itself is one of “prescientific chaos”: cumulative progress. Links to other research domains are vital to establish the business diminishes the added value of business models for organizations and makes business model as a distinct area of investigation. This lack of cohesion in the field clearly modelling an art, rather than a science. A combined solution: Relating Enterprise Architecture and Business Modelling Individually, business modelling or enterprise architecture does not seem to solve the problem completely. However, each of their weaknesses seems to be countered by the strengths of the other. On one side, where EA is limited to experts and lack business strategy, BM is intuitive to use and focusses on the business. On the other side, where an Architecture Development Method, and is standardized in ArchiMate. Therefore, BM lacks a methodology, is barely formalized, and lacks scientific underpinning, EA has combining EA and BM appears to be an advance towards solving our problem. While solving the problem of building and adapting IT systems to business needs, thesis is limited to relating enterprise architecture and business modelling. This thereby increasing success rates of IT implementation projects is the final goal, this thesis proposes a methodology for creating business models, evaluating them, and relating them to enterprise architecture. We do this by developing several steps of the methodology, which supports bringing an organization from its current situation to a target situation. The developed process steps help to formalize business modelling, and at the same time extend enterprise architecture to be more business focussed and easier to use. This would support our hypothesis the combining enterprise architecture and business modelling leads to better EA and BM models, and therefore, more successful business-IT innovations. A meta-meta-view on business modelling One of the main gaps in business model research was the lack of a conceptual model. We introduce a meta-modelling perspective on business models. By placing existing business model review literature in the context of meta-layers and structuring it following the components of design theory, we create the meta-meta-business model (Me2BM). This helps to see what we are talking about in the jungle of business models and their different interpretations. How to create business models? We propose the Business Modelling Method to create business models. This six-step No widely accepted method existed for design and specification of business models. method, named BMM, is developed, demonstrated, and evaluated in this thesis. The VI BMM provides a way to create business models systematically. Innovators can apply the steps to create business cases for their ideas. This helps them to show the viability and get things implemented. How to evaluate business models? Having built one or more business models, a need arises for a method to objectively compare alternative business models, and choose the best course of action. We propose the business case method as a way to evaluate business models. The designed business case method to compare business models objectively can be used to compare and choose the best business model successfully. This is what has to happen in the last step of the BMM. How to relate business models to enterprise architecture? We show how business models and enterprise architecture can be related. The contribution is threefold: 1. We relate Business Model Canvas building blocks to 3. We provide methodological support, clarifying the role of business models in the ArchiMate, 2. We demonstrate the value of that relationship in a cost/benefit-analysis, Architecture Development Method. The U*Care project serves as a case study to demonstrate the above three methods chained together. Business models are created, evaluated, and related to enterprise architecture. Combining enterprise architecture and business modelling leads to better EA and BM models, and therefore, more successful business-IT innovations. In conclusion modelling lies in providing a way to deal with issues from business-IT alignment, by Our main research contribution to the fields of enterprise architecture and business developing a design science methodology for creating business models, evaluating them, and relating them to enterprise architecture.

ABSTRACT In the present climate of global competition, manufacturing organisations consider and seek strategies, means and tools to assist them to stay competitive. Computer Integrated Manufacturing (CIM) offers a number of potential opportunities for improving manufacturing systems. However, a number of researchers have reported the difficulties which arise during the analysis, design and implementation of CIM due to a lack of effective modelling methodologies and techniques and the complexity of the systems. The work reported in this thesis is related to the development of an integrated modelling method to support the analysis and design of advanced manufacturing systems. A survey of various modelling methods and techniques is carried out. The methods SSADM, IDEFO, IDEF1X, IDEF3, IDEF4, OOM, SADT, GRAI, PN, 10A MERISE, GIM and SIMULATION are reviewed.

Bordeaux, CNRS, IMS, UMR 5218, 33405 Talence, France [email protected], [email protected] Abstract During the last thirty years, enterprise modelling has been recognised as an efficient tool to externalise the knowledge of companies in order to understand their operations, to analyse their running and to design new systems from several points of view: functions, processes, decisions, resources, information technology. This paper aims at describing the long evolution of enterprise modelling techniques as well as one of the future challenges of these techniques: the transformation of enterprise models. So, in a first part, the paper describes the evolution of enterprise modelling techniques from the divergence era to the convergence period.

  • Process Model Driven Requirements Engineering
    Process Model Driven Requirements Engineering Dag Rojahn Karlsen1, Helle Frisak Sem1, Steinar Carlsen1 1 Computas AS, Lysaker Torg 45, N-1327 Lysaker, Norway {dag.rojahn.karlsen, helle.frisak.sem, steinar.carlsen}@computas.com Abstract. This paper demonstrates an approach to requirements engineering with process models as the hub for a family of consistent sub-models. The process model taken as a starting point gives focus, and the different requirement perspectives are served through the enrichment of the process model in several dimensions. Different views into the model family give the well-known specification models; information models, exchange models, service models, etc. The family of related sub models are refined iteratively to describe the need for information (NFI), the need for services (NFS), a shared common information model (CIM) and refined domain information models (DIM). We call this family of interrelated sub models of information systems knowledge models, since they capture both the structure and the behaviour of the subject matter domain. Working in an integrated way with several models serves to enhance consistency and to test the quality of each particular model. Keywords: Process models, knowledge models, requirements engineering, enterprise models, information models 1 Background This paper presents an enterprise modelling approach to requirements engineering discovered in our work in a project for a large Norwegian public sector organisation - LNOP. LNOP manages a substantial part of the national budget in Norway and administers a diverse set of schemes under precise regulations. LNOP was established as a merger between two existing organisations, each with a long history. The local authorities and central government cooperate through 456 LNOP offices in municipalities and city boroughs.

  • Business Process Modeling and Design: AI Models and Methodology
    Business Process Modelling and Design: 1 A Formal Model and Methodology 2 Manolis Koubarakis Dimitris Plexousakis Dept. of Informatics Dept. of Computer Science University of Athens University of Crete Panepistimioupolis, TYPA Buildings Heraklion, Crete 157 81 Athens, Greece 713 05 Greece [email protected] [email protected] http://www.di.uoa.gr/ manolis http://www.csee.usf.edu/ ~dimitris Abstract We present a formal framework for representing enterprise knowledge. The concepts of our framework (objectives and goals, roles and actors, actions and processes, responsibilities and constraints) allow business analysts to capture knowledge about an enterprise in a way that is both intuitive and mathematically formal. We also outline the basic steps of a methodology that allows business analysts to go from high-level enterprise objectives, to detailed and formal specifications of business processes that can be enacted to realise these objectives. The formal language used means that the specifications can be verified as having certain correctness properties: we can verify that responsibilities assigned to roles are fulfilled, and constraints are maintained as a result of process execution. 1 Introduction The problem of representing, analysing and managing knowledge about an organisation and its processes has always been very important. Recently, management and computer science researchers have debated the use of information technology for tackling this complex problem 1The work of the first author was partially supported by BT Labs, Ipswich, U.K. through a Short Term Research Fellowship.

  • Modelling the Enterprise Data Architecture Copyright © Andrew K
    Modelling the Enterprise Data Architecture Copyright © Andrew K. Johnston and Richard Wiggins, 2003 Unlike the simplistic models in books and training courses, a real enterprise has a very complicated data architecture. Most of the data will be held in large legacy or package systems, for which the details of data structure may be unknown. Other data will be held in spreadsheets and personal databases (such as Microsoft Access), and may be invisible to the IT department or senior business data administrators. Some key data may reside in external systems maintained by service providers or business partners. As you explore your own complex data architecture, you come to accept two realities: 1. You have little control over the way high-level business data concepts are realised. Data is likely to be highly dispersed, often without adequate controls on quality. 2. Most data is duplicated across a number of systems, with significant variations in quality, format, and meaning. Some of the copies, maintained by Enterprise Application Integration technology (EAI) or careful business processes, may be good (but probably not perfect). Most are very poor, maintained only by occasional batch transfers and stressed or broken manual processes. Organisational and business process conflicts, or simple failures of trust, may get in the way of common sense improvements. The poor copies may be causing business problems. Furthermore, initiatives such as Customer Relationship Management (CRM) and Business Intelligence will need to merge data from various sources. Some organizations work to harness various legacy systems in end-to-end processes. Either the business or IT may be driving changes to simplify business processes, streamline data flows, and reduce duplication.

  • Experiences from Teaching Enterprise Modelling to Students of Information Systems
    Experiences from Teaching Enterprise Modelling to Students of Information Systems Sobah Abbas Petersen1,2 and John Krogstie2 1 SINTEF Technology & Society, Norway [email protected] 2 Norwegian University of Science & Technology, Norway [email protected] Abstract. In this paper, we describe how Masters students at a university study- ing Information Systems adapt to Enterprise Modelling. The paper describes an overview of the course and its design and the feedback from the students based on a questionnaire at the end of the course. The feedback indicates that the stu- dents found it helpful to be able to select their own cases for their modelling as- signment, that they were able to relate their modelling assignment to the real world and the theory taught in the course and that their confidence in modelling improved during the course. Keywords: Enterprise Modelling, Model Evaluation, Modelling Theory, Mod- elling Practice, Aspects of modelling. 1 Introduction The goal of an enterprise model is to support analysis of an enterprise and to model the relevant business processes and how they relate to the rest of the enterprise such as how the work is organized and resource utilisation. Enterprise models and model- ling have been defined by several authors; e.g. Fox and Gruninger describes an enter- prise model as a computational representation of the structure, activities, processes, information, resources, people, behaviour, goals and constraints of a business, gov- ernment, or other enterprise [1]; Bernus defines Enterprise Modelling as a collective name for the use of models in Enterprise Engineering and Enterprise Integration [2]; and Vernadat defines Enterprise Modelling as a consistent set of special purpose and complementary models describing various facets of an enterprise to satisfy some pur- pose of some business users [3].

This state-of-the-art paper first recalls definitions and fundamental principles of enterprise modelling, which goes far beyond process modeling. The CIMOSA modeling framework, which is based on an event-driven process-based modeling language suitable for enterprise system analysis and model enactment, is used as a reference conceptual framework because of its generality. Next, the focus is on new features of enterprise modeling languages including risk, value, competency modeling and service orientation. Extensions for modeling collaborative aspects of networked organizations are suggested as research outlook. Major approaches used in enterprise modeling are recalled before concluding.
