Examines the views of 25 chief executive officers and their information systems executives on the utility of information systems in their organizations. Detects a gap between these two groups of executives with regard to their satisfaction with information systems and those who run them. Concludes that such a gap must be eliminated through training and education, if information systems are to be effective in achieving a strategic competitive advantage for the organization.

A framework is presented based on the MRP Evolution‐Information System Evolution (MEISE) grid to classify MRP users in terms of the diagonal band along the dimension of information processing system development. The classification scheme provides a guideline for the information system specialist to make necessary adjustments of information systems when they decide to upgrade their MRP systems. Furthermore, the MEISE grid also facilitates the organisation of information and production functions while maintaining overall co‐ordination. Finally, the operational implications of deviating from the diagonal band are discussed.

The purpose of this paper is to study a theory of systems and their models on the basis of studying the information channels between their elements, meaning that it is a continuation of those studies already carried out on the theory of systems and their models applied to environmental systems.

The model information transmission system (MITS) can be defined as the theoretical structure that makes it possible to describe the way information is stored and transmitted in a modelling process, and which will be completed in future studies. The basis for a taxonomy of languages is also presented.

The theoretical structure described will lead to the study of a theory of information from the point of view of the analysis of text systems and models, but analysed within the theoretical structure presented, which includes the study of an information source and an information channel.

These theoretical findings will improve the information channels used up to now for the study and modelling of systems and which are largely described using several computer programmes, as the information generated and transmitted will be studied and analysed in different ways. In this way, the text models and families of text models generated can be analysed by studying and transforming models, particularly by focusing attention on everything inherent to the information contained in the same.

Management information systems providers are often still failing to deliver appropriate systems to the perceived user specifications. A major problem is a lack of strategic perspective of information systems and their supporting information technology and a disparate view across organizations of what management information systems are. Investigates some aspects of these problems and suggests a portfolio methodology for improving the incorporation of system building into the overall business objectives.

We introduce the concepts of information, uncertainty information, systems and uncertainty systems, analyze the intension of these concepts, and point out the differences and connections among various concepts of systems. We put forward a mathematical method to research uncertainty systems and present a problem that can be solved with our method but cannot be solved with the interval analyzing method. Otherwise, from analyzing the purpose of introducing the concepts of information, uncertainty information, systems and uncertainty systems, we conclude that uncertainty information and uncertainty systems are among the most important subjects studied in scientific research, especially in applied research, both that being presently conducted and the abundance which is to come in the future.

Today, business organizations compete in the global marketplace. To compete successfully, organizations pursue the status of the world‐class organization (WCO). A WCO is defined as the best in its class, or as good as its best global competitor, in providing most value to the customer. The strategic pillars that enable an organization to become a WCO must be supported by effective information systems. Conventional information systems development approaches are not necessarily relevant for WCOs. Presents new approaches to developing the information for world‐class organizations.

Contends that information systems planning, development, maintenance and utilization in the area of libraries involve such complicated procedures and techniques that good results cannot be expected without their knowledgeable management. The situation in the libraries and information centres in Slovakia is similar to that in other countries, especially after the socio‐political changes in 1989 when a shift towards a more market‐oriented approach appeared. The education of information systems managers is carried out in the framework of a five‐year Master′s programme in library and information science at the department of library and information science in Bratislava. The principal methodological course for the area of information systems management is the “Theory of library and information systems”. Outlines the content of the course and reflects the principal problem areas. Mentions other courses and programme orientations connected with library management.

It is no longer enough for information systems (IS) to support the operation. Information systems should be developed as part of the strategic plan of the organization. We first must recognize the culture and the financial position of the business before assessing whether an IS is worth investing in; together with the information technology department we must take into account what technical support we already have and if we can make enough use of it. Planning must be well structured but on assessing various planning methods we find that this task is best handled by experienced teams that may consist ideally of IS staff and management combined. Information systems are costly and slow to develop, so we must plan well and in line with the strategic policy of our business.

Argues that a good marketing information system can make decision making more efficient and effective. It can be used to help create a competitive advantage, and can even substitute for expensive assets. Analyses data from a survey conducted by the authors in Queensland, Australia, and finds that even though SME managers recognize the value of marketing information systems, they have generally done little to develop them so far. This is true for services as well as other industry sectors. Identifies exceptions and outlines one example. Finds that this network of firms derives considerable benefits from its marketing information system. Concludes by presenting seven maxims for the development of a sound marketing information system.
