Models are incredibly insidious; they slide undetected into discussions and then dominate the way people think. Since Information Systems (ISs) and particularly Knowledge Management Systems (KMSs) are socio-technical systems, they unconsciously embrace the characteristics of the dominant models of management thinking. Thus, their limitations can often be attributed to the deficiencies of the organizational models they aim to support. Through the case study of a hotel chain, this research suggests that contemporary KMSs in the hospitality sector are still grounded in the assumptions of the mechanistic organizational model which conceives an organization as a rigid hierarchical entity governed from the top. Despite the recent technological advances in terms of supporting dialogue and participation between members, organizational knowledge is still transferred vertically; from the top to the bottom or from the bottom to the top. A number of limitations still exist in terms of supporting effectively the transfer of knowledge horizontally between the geographically distributed units of an organization. Inspired from the key concepts of the more recent complex systems model, referred frequently as complexity theories, a Knowledge Management Architecture (KMA) is proposed aiming to re-conceptualize the existing KMSs towards conceiving an organization as a set self-organizing communities of practice (CoP). In every such CoP, order is created from the dynamic exchange of knowledge between the structurally similar community members. Thus, the focus of the KMA is placed on capturing systematically for reuse the architectural knowledge created upon every initiative for change and share such knowledge with the rest of the members of the CoP. A KMS was also developed to support the dynamic dimensions that the KMA proposes. The KMS was then applied in the case of the hotel chain, where it brought significant benefits which constitute evidence of an improved self-organizing ability. The previously isolated hotel units residing in distant regions could now trace but also reapply easily changes undertaken by the other community members. Top-management’s intervention to promote change was reduced, while the pace of change increased. Moreover, the organizational cohesion, the integration of new members as well as the level of management alertness was enhanced. The case of the hotel chain is indicative. It is believed that the KMA proposed can be applicable to geographically distributed organizations operating in different sectors too. At the same time, this research contributes to the recent discourse between the fields of IS and complexity by demonstrating how fundamental concepts from complexity such as self-organization, emergence and edge-of-chaos can be embraced by contemporary KMSs.

This thesis follows up two views on the data migration project. First of all there is a basic description of data migration within MBI model. This model is created by information technology department on the University of Economy in Prague. The thesis fills in this model data migration task and related objects as task roles or documents. In the next part the thesis focus on concrete project of implementation of core banking system. More detail is dedicated to the data migration part of this project. First there are described principles of work in data migration and next the thesis aims on data model of data migration which is used as a documentary tool. This model is evaluated from the benefits and risks view for data migration and next there are described creation and updating of it. These activities are provided mostly by macros in VBA script language, which are created here for these purposes. In the end some options of model extension are designed and evaluated.

Information is the currency of our world. Making right decisions requires having reliable, comprehensive and thorough information still at hand. The tools that can provide it? Information systems. However, the purpose of today's information systems is more than to just collect and store information: they need to integrate numerous data sources (both internal and external), identify essential pieces of information and set them apart from the rest, and provide the people relying on them a clear picture of the situation. In short: they should offer unified, user-friendly, well-structured and comprehensive view of business reality. This paper focuses on the first stage of an information system design. Concerned primarily with the business analytical phases of an IT project, it presents an insight into the process of business reality exploration and description through conceptual data model and architecture vision articulation.

Syftet med föreliggande arbete är att undersöka hur företag och organisationer förvaltar sina informationssystem, om Applicerad Modell (Hafström, Nordström; 1991) innehåller de delar som krävs för en fungerande systemförvaltning samt att med ledning av erhållen information diskutera kring problem och möjligheter med systemförvaltning. Vi genomförde en litteraturstudie och intervjuade personer som är inblandade I systemförvaltningsprocessen. Resultatet av litteraturstudien presenteras genom definitioner av begrepp och resultatet av tre vägledande undersökningar. Därefter presenteras en sammanfattning av de intervjuer vi genomfört. Utifrån erhållen information utvecklar vi definitionen av systemförvaltningsbegreppet. Applicerad Modell utvecklas och resultatet blir en ny modell kallad Raket Förvaltningsmodell. Vidare diskuterar vi kring problem och möjligheter med systemförvaltning och slutligen ges synpunkter på hur man skall starta arbetet med att strukturera systemförvaltningsprocessen. / The aim with the present work is to examine how corporations and organizations maintain their information systems, if the Applied Mode! (Hafström, Nordström; 1991) contain all parts required for working system maintenance and according to this discuss problems and possibilities of system maintenance. We realized a literature study and interviewed people who are involved in the process of system maintenance. The result of the literature study is presented by definitions of conceptions and the result of three examinations. A summary of the interviews is made. From the received information we developed the definition of the system maintenance conception. Applied Mode! is developed and the result is Rocket Maintenance Model. Further on we discuss problems and possibilities of system maintenance and finally we are giving our opinion how to start the work by structuring the system maintenance process.

This thesis focuses on the use and application of strategic tool Balanced Scorecard (BSC) for managing banking institution and translation the strategy into particular objectives and initiatives. Theoretical background affects both BSC framework taking into account modern trends of the dynamic system conception and also basics of information society, strategic considerations and system dynamics theory in relation to creating and application of the BSC in the organization. The practical part provides an introduction to the issues of examined institution, the current state of sharing strategic objectives, fundamental analysis to detect key features of the organization and the market and especially BSC formation.

Die "Kontextsensitivität" genannte systematische Berücksichtigung von Umweltinformationen durch Anwendungssysteme kann als Querschnittsfunktion im betrieblichen Umfeld in vielen Bereichen einen Nutzen stiften. Wirklich praxistaugliche kontextsensitive Anwendungssysteme, die sich analog zu einem mitdenkenden menschlichen Assistenten harmonisch in die ablaufenden Vorgänge in der Realwelt einbringen, haben einen enormen Bedarf nach umfassenden, d.h. diverse Aspekte der Realwelt beschreibenden Kontextinformationen, die jedoch prinzipbedingt verteilt in verschiedenen Datenquellen, etwa Kontexterfassungssystemen, Endgeräten sowie prinzipiell auch in beliebigen anderen, z.T. bereits existierenden Anwendungen entstehen. Ziel dieser Arbeit ist die Verringerung der Komplexität des Beschaffungsvorganges von verteilten und heterogenen Kontextinformationen durch Bereitstellung einer einfach verwendbaren Methode zur Darstellung eines umfassenden, aus verteilten und heterogenen Datenquellen zusammengetragenen Kontextmodells. Im Besonderen werden durch diese Arbeit zwei Probleme addressiert, zum einen daß ein Konsument von umfassenden Kontextinformationen mehrere Datenquellen sowohl kennen und zugreifen können und zum anderen über die zwischen den einzelnen Kontextinformationen in verschiedenen Datenquellen existierenden, zunächst nicht modellierten semantischen Verbindungen Bescheid wissen muß. Das dazu entwickelte Kontextinformationsintegrations- und -darstellungsverfahren kombiniert daher ein die Beschaffung und Integration von Kontextinformationen aus diversen Datenquellen modellierendes Informationsintegrationsmodell mit einem Kontextdarstellungsmodell, welches die abzubildende Realweltdomäne basierend auf ontologischen Informationen durch in problemspezifischer Weise erweiterte Verfahren des Semantic Web in einer möglichst intuitiven, wiederverwendbaren und modularen Weise modelliert. Nach einer fundierten Anforderungsanalyse des entwickelten Prinzips wird dessen Verwendung und Nutzen basierend auf der Skizzierung der wichtigsten allgemeinen Verwendungsmöglichkeiten von Kontextinformationen im betrieblichen Umfeld anhand eines komplexen betrieblichen Anwendungsszenarios demonstriert. Dieses beinhaltet ein Nutzerprofil, das von diversen Anwendungen, u.a. einem kontextsensitiven KFZ-Navigationssystem, einer Restaurantsuchanwendung sowie einem Touristenführer verwendet wird. Probleme hinsichtlich des Datenschutzes, der Integration in existierende Umgebungen und Abläufe sowie der Skalierbarkeit und Leistungsfähigkeit des Verfahrens werden ebenfalls diskutiert. / Context-awareness, which is the systematic consideration of information from the environment of applications, can provide significant benefits in the area of business and technology. To be really useful, i.e. harmonically support real-world processes as human assistants do it, practical applications need a comprehensive and detailed contextual information base that describes all relevant aspects of the real world. As a matter of principle, comprehensive contextual information arises in many places and data sources, e.g. in context-aware infrastructures as well as in "normal" applications, which may have knowledge about the context based on their functionality to support a certain process in the real world. This thesis facilitates the use of contextual information by reducing the complexity of the procurement process of distributed and heterogenous contextual information. Particularly, it addresses the two problems that a consumer of comprehensive contextual information needs to be aware of and able to access several different data sources and must know how to combine the contextual information taken from different and isolated data sources into a meaningful representation of the context. Especially the latter information cannot be modelled using the current state of the art. These problems are addressed by the development of an integration and representation model for contextual information that allows to compose comprehensive context models using information inside distributed and heterogeneous data sources. This model combines an information integration model for distributed and heterogenous information (which consists of an access model for heterogeneous data sources, an integration model and an information relation model) with a representation model for context that formalizes the representation of the respective real world domain, i.e. of the real world objects and their semantic relations in an intuitive, reusable and modular way based on ontologies. The resulting model consists of five layers that represent different aspects of the information integration solution. The achievement of the objectives is rated based on a requirement analysis of the problem domain. The technical feasibility and usefulness of the model is demonstrated by the implementation of an engine to support the approach as well as a complex application scenario consisting of a user profile that integrates information from several data sources and a couple of context-aware applications, e.g. a context-aware navigation system, a restaurant finder application as well as an enhanced tourist guide that use the user profile. Problems regarding security and social effects, the integration of this solution into existing environments and infrastructures as well as technical issues like the scalability and performance of this model are discussed too.
