Developing Information Systems to Support Flexible Strategy

The literature on strategic applications of information technology(IT) and strategic information systems (SIS) contains a number of "classic" success cases. These systems are successful in terms of one particular strategy framework, but there is evidence that the demands placed upon SIS are changing. Changes in the business environment and in the rate of development of technology have created a requirement for more flexibility in the strategic process. This must be supported by a "new generation" of SIS that integrate with flexible infrastructures to provide long-term effective support for a flexible business strategy. This article looks at the changing nature of the strategic: process and examines a framework that has potential to assist in these aims. A number of techniques are analyzed to assess their capability for identifying strategic applications of IT. Finally, a way of providing a flexible IS/IT infrastructure relevant to the development of a flexible SIS is discussed.     

Evolutionary Business Information Systems

This article reflects on existing and emerging future challenges arising in the area of “evolutionary business information systems”, a class of systems that demand an evolutionary software development process and which support secondary design of various conceptual layers. We place both existing contributions and future research opportunities in context by referring to an idealized, preliminary system architecture. Finally, we emphasize our pluralistic perspective on the research object and the resulting need for methodological flexibility in the sense of interdisciplinary configurations of research methods.     

Internationalizing the Information Systems Curriculum

This paper provides a systems model for curriculum developers who wish to add appropriate international content to the business curriculum. The major factors which determine the degree of internationalization and the method of effecting change are viewed as inputs to a subsystem; graduating students are the principal outputs. While the primary focus of the article is on the information systems function, the approach is applicable to other business disciplines as well. A guide to recent literature on international curriculum development is included.

The Dynamics of SME Information Systems

The process by which small firms (SMEs) invest in and gain benefit from information systems (IS) is little understood. This paper analyses two alternative models of IS-based strategic change – the Focus-Dominance model (Levy et al., 2001) and stages of growth models as applied to SMEs. An analysis of the outcomes of IS strategy development undertaken for 43 SMEs maps their IS use over time. The analysis supports the Focus-Dominance model, some parts of the stages of growth model and extends the critique of the latter. Further variances are explained by the entrepreneur/owner's values and experience. One structural variable, namely, the industry sector may also explain the variances. The implications for theory and practice are discussed.     

Method Support of Information Requirements Analysis for Analytical Information Systems

Due to specific characteristics of analytical information systems, their development varies significantly from transaction-oriented systems. Specific method support is particularly needed for requirements engineering and its information-related component, information requirements analysis. The paper at hand first evaluates the state of the art and identifies necessary method support extensions. On this basis, method support requirements for information requirements engineering are identified. The survey is structured along the five core activities of traditional requirements engineering. It reveals a need for further research especially on information requirements elicitation, validation, and management. It further contributes to a discussion of aspects that should be considered by any method support. Due to comparatively long life cycles of analytical information systems, the introduction of a process perspective is discussed in order to ensure the continuous elicitation, documentation, and management of information requirements.     

Robust Multi-criteria Service Composition in Information Systems

Service compositions are used to implement business processes in a variety of application domains. A quality of service (QoS)-aware selection of the service to be composed involves multiple, usually conflicting and possibly uncertain QoS attributes. A multi-criteria solution approach is desired to generate a set of alternative service selections. In addition, the uncertainty of QoS-attributes is neglected in existing solution approaches. Hence, the need for service reconfigurations is imposed to avoid the violation of QoS restrictions. The researched problem is NP-hard. This article presents a heuristic multi-criteria service selection approach that is designed to determine a Pareto frontier of alternative service selections in a reasonable amount of time. Taking into account the uncertainty of response times, the obtained service selections are robust with respect to the constrained execution time. The proposed solution approach is based on the Non-dominated Sorting Genetic Algorithm (NSGA)-II extended by heuristics that exploit problem specific characteristics of the QoS-aware service selection. The applicability of the solution approach is demonstrated by a simulation study.     

Information Systems Ethics: A Practitioner Survey

Fortune 500 non-management employees who work in their company's information systems department were polled via a mail survey; of 191 surveys sent (one to a company), 123 (64%) were returned. Virtually all respondents (97%) indicated that management should define ethical computer use for employees. A majority of respondents (60%) reported that the method management uses to do this should be some form of consensus building. Almost two thirds of respondents (63%) reported that the definition of ethical computer use was well known in their organization. Finally, over half of the respondents (55%) had no personal knowledge that computer abuse occurred in their organization – a surprisingly favorable finding. Of responses indicating knowledge of computer abuse, only about a quarter (26%) indicated direct evidence of the problem.

The State of Research on Information Systems Success

Measuring information systems (IS) success is of great interest to both researchers and practitioners. This article examines multidimensional approaches to measuring IS success and explores the current state of IS success research through a literature review and by classifying articles published between 2003 and 2007. Based on a total of 41 academic journal and conference publications, the relevant research carried out is identified, while the research results are categorized, consolidated, and discussed. The results show that the dominant empirical research analyzes the individual impact of a certain type of information system by ascertaining users’ evaluation of it by means of surveys and then applying structural equation modeling. The DeLone and McLean information systems success model is the main theoretical basis of the reviewed empirical studies. This article provides researchers with a comprehensive review and structuring of IS success research. Furthermore, opportunities for additional development are identified and future research directions suggested.     

SME Flexibility and the Role of Information Systems

Small and medium-size enterprises (SMEs) are a major component of all economies and are generally considered to be flexible, adaptive organisations. Although lagging behind their larger counterparts, SMEs are beginning to invest in information systems. Using data derived from a set of manufacturing SMEs located in the U.K., this paper investigates whether SMEs really do exhibit flexibility and if their use of information technology enhances or inhibits such flexibility.     

A Workflow-Based Methodology for Developing Hypermedia Information Systems

Recently, many enterprises have attempted to construct hypermedia systems for electronic commerce innovation by the use of Internet technologies. In this hypermedia-enabled environment, hypermedia development can be considered in terms of workflow. In this article we propose a workflow-aware hypermedia development methodology, workflow-based hypermedia development methodology, to guide developers in creating hypermedia information systems. The methodology employs a workflow model based on corporate documents and is thus more likely to utilize users' business requirements in a natural fashion. The methodology consists of four phases: workflow analysis, document analysis, hypermedia design, and implementation. The emphasis of each phase is on aligning business requirements with hypermedia development technologies. To demonstrate the practical usefulness of the methodology, a real-life case is illustrated.
