Conceptual models for designing information systems supporting the strategic analysis of technology environments

1 6 STRUCTURE OF THIS THESIS -Chapter I presents the motivations of this dissertation by illustrating two gaps in the current body of knowledge that are worth filling, describes the research problem addressed by this thesis and presents the research methodology used to achieve this goal. -Chapter 2 shows a review of the existing literature showing that environment analysis is a vital strategic task, that it shall be supported by adapted information systems, and that there is thus a need for developing a conceptual model of the environment that provides a reference framework for better integrating the various existing methods and a more formal definition of the various aspect to support the development of suitable tools. -Chapter 3 proposes a conceptual model that specifies the various enviromnental aspects that are relevant for strategic decision making, how they relate to each other, and ,defines them in a more formal way that is more suited for information systems development. -Chapter 4 is dedicated to the evaluation of the proposed model on the basis of its application to a concrete environment to evaluate its suitability to describe the current conditions and potential evolution of a real environment and get an idea of its usefulness. -Chapter 5 goes a step further by assembling a toolbox describing a set of methods that can be used to analyze the various environmental aspects put forward by the model and by providing more detailed specifications for a number of them to show how our model can be used to facilitate their implementation as software tools. -Chapter 6 describes a prototype of a strategic decision support tool that allow the analysis of some of the aspects of the environment that are not well supported by existing tools and namely to analyze the relationship between multiple actors and issues. The usefulness of this prototype is evaluated on the basis of its application to a concrete environment. -Chapter 7 finally concludes this thesis by making a summary of its various contributions and by proposing further interesting research directions.

The business model ontology a proposition in a design science approach

The goal of this dissertation is to find and provide the basis for a managerial tool that allows a firm to easily express its business logic. The methodological basis for this work is design science, where the researcher builds an artifact to solve a specific problem. In this case the aim is to provide an ontology that makes it possible to explicit a firm's business model. In other words, the proposed artifact helps a firm to formally describe its value proposition, its customers, the relationship with them, the necessary intra- and inter-firm infrastructure and its profit model. Such an ontology is relevant because until now there is no model that expresses a company's global business logic from a pure business point of view. Previous models essentially take an organizational or process perspective or cover only parts of a firm's business logic. The four main pillars of the ontology, which are inspired by management science and enterprise- and processmodeling, are product, customer interface, infrastructure and finance. The ontology is validated by case studies, a panel of experts and managers. The dissertation also provides a software prototype to capture a company's business model in an information system. The last part of the thesis consists of a demonstration of the value of the ontology in business strategy and Information Systems (IS) alignment. Structure of this thesis: The dissertation is structured in nine parts: Chapter 1 presents the motivations of this research, the research methodology with which the goals shall be achieved and why this dissertation present a contribution to research. Chapter 2 investigates the origins, the term and the concept of business models. It defines what is meant by business models in this dissertation and how they are situated in the context of the firm. In addition this chapter outlines the possible uses of the business model concept. Chapter 3 gives an overview of the research done in the field of business models and enterprise ontologies. Chapter 4 introduces the major contribution of this dissertation: the business model ontology. In this part of the thesis the elements, attributes and relationships of the ontology are explained and described in detail. Chapter 5 presents a case study of the Montreux Jazz Festival which's business model was captured by applying the structure and concepts of the ontology. In fact, it gives an impression of how a business model description based on the ontology looks like. Chapter 6 shows an instantiation of the ontology into a prototype tool: the Business Model Modelling Language BM2L. This is an XML-based description language that allows to capture and describe the business model of a firm and has a large potential for further applications. Chapter 7 is about the evaluation of the business model ontology. The evaluation builds on literature review, a set of interviews with practitioners and case studies. Chapter 8 gives an outlook on possible future research and applications of the business model ontology. The main areas of interest are alignment of business and information technology IT/information systems IS and business model comparison. Finally, chapter 9 presents some conclusions.

Ambulatory healthcare information system: a conceptual framework

Despite the tremendous amount of data collected in the field of ambulatory care, political authorities still lack synthetic indicators to provide them with a global view of health services utilization and costs related to various types of diseases. Moreover, public health indicators fail to provide useful information for physicians' accountability purposes. The approach is based on the Swiss context, which is characterized by the greatest frequency of medical visits in Europe, the highest rate of growth for care expenditure, poor public information but a lot of structured data (new fee system introduced in 2004). The proposed conceptual framework is universal and based on descriptors of six entities: general population, people with poor health, patients, services, resources and effects. We show that most conceptual shortcomings can be overcome and that the proposed indicators can be achieved without threatening privacy protection, using modern cryptographic techniques. Twelve indicators are suggested for the surveillance of the ambulatory care system, almost all based on routinely available data: morbidity, accessibility, relevancy, adequacy, productivity, efficacy (from the points of view of the population, people with poor health, and patients), effectiveness, efficiency, health services coverage and financing. The additional costs of this surveillance system should not exceed Euro 2 million per year (Euro 0.3 per capita).

Dynamics of IS Adaptation in Multinational Corporations: A New Theoretical Lens

The specificities of multinational corporations (MNCs) have to date not been a focus area of IS research. Extant literature mostly proposes IS configurations for specific types of MNCs, following a static and prescriptive approach. Our research seeks to explain the dynamics of global IS design. It suggests a new theoretical lens for studying global IS design by applying the structural adjustment paradigm from organizational change theories. Relying on archetype theory, we conduct a longitudinal case study to theorize the dynamics of IS adaptation. We find that global IS design emerges as an organizational adaptation process to balance interpretative schemes (i.e. the organization's values and beliefs) and structural arrangements (i.e. strategic, organizational, and IS configurations). The resulting insights can be used as a basis to further explore alternative global IS designs and movements between them.

Impacts des technologies de l'information sur les modes de coordination à travers quatre études en systèmes d'information

L'évolution de l'environnement économique, des chaînes de valeur et des modèles d'affaires des organisations augmentent l'importance de la coordination, qui peut être définie comme la gestion des interdépendances entre des tâches réalisées par des acteurs différents et concourants à un objectif commun. De nombreux moyens sont mis en oeuvre au sein des organisations pour gérer ces interdépendances. A cet égard, les activités de coordination bénéficient massivement de l'appui des technologies de l'information et de communication (TIC) qui sont désormais disséminées, intégrées et connectées sous de multiples formes tant dans l'environnement privé que professionnel. Dans ce travail, nous avons investigué la question de recherche suivante : comment l'ubiquité et l'interconnec- tivité des TIC modifient-elles les modes de coordination ? A travers quatre études en systèmes d'information conduites selon une méthodologie design science, nous avons traité cette question à deux niveaux : celui de l'alignement stratégique entre les affaires et les systèmes d'information, où la coordination porte sur les interdépendances entre les activités ; et celui de la réalisation des activités, où la coordination porte sur les interdépendances des interactions individuelles. Au niveau stratégique, nous observons que l'ubiquité et l'interconnectivité permettent de transposer des mécanismes de coordination d'un domaine à un autre. En facilitant différentes formes de coprésence et de visibilité, elles augmentent aussi la proximité dans les situations de coordination asynchrone ou distante. Au niveau des activités, les TIC présentent un très fort potentiel de participation et de proximité pour les acteurs. De telles technologies leur donnent la possibilité d'établir les responsabilités, d'améliorer leur compréhension commune et de prévoir le déroulement et l'intégration des tâches. La contribution principale qui émerge de ces quatre études est que les praticiens peuvent utiliser l'ubiquité et l'interconnectivité des TIC pour permettre aux individus de communi-quer et d'ajuster leurs actions pour définir, atteindre et redéfinir les objectifs du travail commun. -- The evolution of the economic environment and of the value chains and business models of organizations increases the importance of coordination, which can be defined as the management of interdependences between tasks carried out by different actors and con-tributing to a common goal. In organizations, a considerable number of means are put into action in order to manage such interdependencies. In this regard, information and communication technologies (ICT), whose various forms are nowadays disseminated, integrated and connected in both private and professional environments, offer important support to coordination activities. In this work, we have investigated the following research question: how do the ubiquity and the interconnectivity of ICT modify coordination mechanisms? Throughout four information systems studies conducted according to a design science methodology, we have looked into this question at two different levels: the one of strategic alignment between business and information systems strategy, where coordination is about interdependencies between activities; and the one of tasks, where coordination is about interdependencies between individual interactions. At the strategic level, we observe that ubiquity and interconnectivity allow for transposing coordination mechanisms from one field to another. By facilitating various forms of copresence and visibility, they also increase proximity in asynchronous or distant coordination situations. At the tasks level, ICTs offer the actors a very high potential for participation and proximity. Such technologies make it possible to establish accountability, improve common understanding and anticipate the unfolding and integration of tasks. The main contribution emerging from these four studies is that practitioners can use the ubiquity and interconnectivity of ICT in order to allow individuals to communicate and adjust their actions to define, reach and redefine the goals of common work.

Compliance management is becoming a major issue in IS design

This article aims at improving the information systems management support to Risk and Compliance Management process, i.e. the management of all compliance imperatives that impact an organization, including both legal and stra- tegically self-imposed imperatives. We propose a process to achieve such regula- tory compliance by aligning the Governance activities with the Risk Management ones, and we suggest Compliance should be considered as a requirement for the Risk Management platform. We will propose a framework to align law and IT compliance requirements and we will use it to underline possible directions of investigation resumed in our discussion section. This work is based on an exten- sive review of the existing literature and on the results of a four-month internship done within the IT compliance team of a major financial institution in Switzer- land, which has legal entities situated in different countries.
