Enterprise Modelling (EM) methods are frequently used by entrepreneurs as an analysis tool for describing and redesigning their businesses. The resulting product, an enterprise model, is commonly used as a blueprint for reconstructing organizations and such effort is often a part of business process re-engineering and improvement initiatives.

Automating Business Modelling describes different techniques of providing automated support for enterprise modelling methods and introduces universally used approaches. A running example of a business modelling method is included; providing a framework and detailed explanation as to how to construct automated support for modelling, allowing readers to follow the method to create similar support.

Suitable for senior undergraduates and postgraduates of Business Studies, Computer Science and Artificial Intelligence, practitioners in the fields of Knowledge Management, Enterprise Modelling and Software Engineering, this book offers insight and know-how to both student and professional.

Whilst Information Systems has the potential to widen our view of the world, it often has the opposite effect by limiting our ability to interact, facilitating managerial and state surveillance or instituting strict hierarchies and personal control. In this book, Bernd Stahl offers an alternative and critical perspective on the subject, arguing that the ongoing problems in this area could be caused by the misconceptualization of the nature and role of IS. Stahl discusses the question of how IS can be used to actually overcome oppression and promote emancipation, breaking the book into four sections. The first section covers the theory of critical research in IS, giving a central place for the subject of ethics. The second section discusses the philosophical underpinnings of this critical research. The third and largest section gives examples of the application of critical work in IS. The final section then reflects on the approach and suggests ways for further development.

The authors present a number of financial market studies that have as their general theme, the econometric testing of the underlying econometric assumptions of a number of financial models. More than 30 years of financial market research has convinced the authors that not enough attention has been paid to whether the estimated model is appropriate or, most importantly, whether the estimation technique is suitable for the problem under study. For many years linear models have been assumed with little or no testing of alternative specification. The result has been models that force linearity assumptions on what clearly are nonlinear processes. Another major assumption of much financial research constrains the coefficients to be stable over time. This critical assumption has been attacked by Lucas (1976) on the grounds that when economic policy changes, the coefficients of macroeconomics models change. If this occurs, any policy forecasts of these models will be flawed. In financial modeling, omitted (possibly non-quantifiable) variables will bias coefficients. While it may be possible to model some financial variables for extended periods, in other periods the underlying models may either exhibit nonlinearity or show changes in linear models. The authors research indicates that tests for changes in linear models, such as recursive residual analysis, or tests for episodic nonlinearity can be used to signal changes in the underlying structure of the market.

The book begins with a brief review of basic linear time series techniques that include autoregressive integrated moving average models (ARIMA), vector autoregressive models (VAR), and models form the ARCH/GARCH class. While the ARIMA and VAR approach models the first moment of a series, models of the ARCH/GARCH class model both the first moment and second moment which is interpreted as conditional or explained volatility of a series. Recent work on nonlinearity detection has questioned the appropriateness of these essentially linear approaches. A number of such tests are shown and applied for the complete series and a subsets of the series. A major finding is that the structure of the series may change over time. Within the time frame of a study, there may be periods of episodic nonlinearity, episodic ARCH and episodic nonstationarity. Measures are developed to measure and relate these events both geographically and with mathematical models. This book will be of interest to applied finance researchers and to market participants.

Information technology has had a major impact on individuals, organizations and society over the past 50 years. There are few organizations that can afford to ignore IT and few individuals who would prefer to be without it. As managerial tasks become more complex, so the nature of the required information systems (IS) changes - from structured, routine support to ad hoc, complex enquiries at the highest levels of management. Global Information Systems aims to present the many complex and inter-related issues associated with culture in the management of information systems.

This is a selection of papers representing the best thinking of leading researchers and practitioners in the field of management of technology. Based on a conference on growth through business innovation and entrepreneurship, it addresses a wide range of starting points for technology and innovation managers on how to develop and commercialize new technologies. The book is structured along three themes: entrepreneurship and venture creation; knowledge management; and multi-actor innovation. The first theme essentially deals with entrepreneurial energy, the conditions for its appearance and its success. It focuses mostly on entrepreneurs in innovation, start-ups and venturing activities. The second theme is composed of articles addressing various issues of knowledge and know-how management - the role that information and technologies play to facilitate and create new business opportunities. The third theme discusses the trend towards a multi-actor innovation process, according to which developments are carried out by several organizations, firms or otherwise, each contributing a piece of the innovation puzzle. The concentration is on three areas: the actual implementation of collaborative developments, involving various types of partners; supply and demand chains; and the interplay between technology and its societal context.

The globalization of everyday business and increasing international trade lead to a growing need to improve national and international business collaborations and transactions. Upcoming new technologies for e-business transactions allow for new ways of process, information and application integration. But business partners almost always have different ways to systemize the information needed to run the business, in terms of information structure, syntax and semantics. Consequences are mismatch and misunderstanding in electronic transactions. This book shows what ontology management can do for process, information and application integration under dynamic e-business conditions. We not only discuss research results and develop novel methods and frameworks, but also apply them to build business use application components that are deployed as web services.

This book offers a comprehensive guide to implementing SAP and HANA on private, public and hybrid clouds. Cloud computing has transformed the way organizations run their IT infrastructures: the shift from legacy monolithic mainframes and UNIX platforms to cloud based infrastructures offering ubiquitous access to critical information, elastic provisioning and drastic cost savings has made cloud an essential part of every organization's business strategy. Cloud based services have evolved from simple file sharing, email and messaging utilities in the past, to the current situation, where their improved technical capabilities and SLAs make running mission-critical applications such as SAP possible. However, IT professionals must take due care when deploying SAP in a public, private or hybrid cloud environment. As a foundation for core business operations, SAP cloud deployments must satisfy stringent requirements concerning their performance, scale and security, while delivering measurable improvements in IT efficiency and cost savings. The 2nd edition of "SAP on the Cloud" continues the work of its successful predecessor released in 2013, providing updated guidance for deploying SAP in public, private and hybrid clouds. To do so, it discusses the technical requirements and considerations necessary for IT professionals to successfully implement SAP software in a cloud environment, including best-practice architectures for IaaS, PaaS and SaaS deployments. The section on SAP's in-memory database HANA has been significantly extended to cover Suite on HANA (SoH) and the different incarnations of HANA Enterprise Cloud (HEC) and Tailored Datacenter Integration (TDI). As cyber threats are a significant concern, it also explores appropriate security models for defending SAP cloud deployments against modern and sophisticated attacks. The reader will gain the insights needed to understand the respective benefits and drawbacks of various deployment models and how SAP on the cloud can be used to deliver IT efficiency and cost-savings in a secure and agile manner.

This book presents real-world decision support systems, i.e., systems that have been running for some time and as such have been tested in real environments and complex situations; the cases are from various application domains and highlight the best practices in each stage of the system's life cycle, from the initial requirements analysis and design phases to the final stages of the project. Each chapter provides decision-makers with recommendations and insights into lessons learned so that failures can be avoided and successes repeated. For this reason unsuccessful cases, which at some point of their life cycle were deemed as failures for one reason or another, are also included. All decision support systems are presented in a constructive, coherent and deductive manner to enhance the learning effect. It complements the many works that focus on theoretical aspects or individual module design and development by offering 'good' and 'bad' practices when developing and using decision support systems. Combining high-quality research with real-world implementations, it is of interest to researchers and professionals in industry alike.

This book is intended to mark the turn of the first century of the information age. The purpose of the book is to denote the transition from past to current to future investigations of the relationships and interactions among four major components: information systems (IS), information technology (IT), organizations, and society. These investigations share a primary focus on the interrelationships, not on the components themselves. The contributions to the book deal with the history of IS theory and technology, with the directions faced by those sharing the concerns of the field in its future research, and with attempts to draw these two views together. Five discourses collectively answer the key question: What is the status of IS, as related to organizations and society, now that we stand at the juncture of the new century?' These discourses deal with the fundamental concepts, the classical and novel challenges, the conceptualization processes, automation, and new technology. What is our story as we turn the first century of the information age? We believe that IT is even more critical in social interaction in organizations, that human language barriers form fundamental roadblocks to IT implementation, that newer forms of IS integrate horizontally rather than vertically, and that the mix of skills and knowledge is changing. We also find that we lack integrated approaches to risk management, that new social costs are being unleashed on people by the wiring of society, and we are rushing headlong into globalized systems with our eyes closed. We reveal how the old end-user tension between central control and innovation has reappeared in the intranet world, how IT has been converted into acultural commodity, and explore how the video screen has become the central means for discovering our relevance to our universe. We explore the surprising ways that machines have acquired human status, not through robotics, but rather through social construction. We discover new norms for defining the relationships and exchanges between human beings and computers. For example, gender defines IS success and web design defines social relationships. Consequently, we show how systems must now be developed interpretively, rather than through rational&endash;technical IS design principles used in the last century.

Hsu and Pant in Innovative Planning for Electronic Commerce and Enterprises: A Reference Model have proposed a management planning model for developing strategic goals for e-commerce enterprises. The authors feel they may be provocative sometimes; however, the field is so new that there is no working model for an e-commerce enterprise with a proven success record. In this book, Hsu and Pant develop a framework for a working model. This framework has three parts: (1) The first part is the planning model and a methodology. The planning model is based on principles derived from the literature and the author's research. The methodology also uses Value Chain Analysis to connect e-commerce goals with business processes. (2) The second part evaluates the model and calibrates it to industrial cases and established scholarly results in the field. (3) The last part consists of three exploratory plans for some industrial applications, including supply chain integration, Internet banking, and customer service (ordering) for heavy industry. About fifty cases are discussed in the book at various degrees of depth. The three industrial cases illustrate how to apply the planning model using the methodology. Hence, the book's e-commerce reference model is obtained from the planning model, its methodology, and the industrial benchmarks.
