Porters classic diagram representing these forces is reproduced in Exhibit. Enterprises, through their strategies, can influence the five forces and the industry structure, at least to some extent. There are two basic strategic stances that enterprises can adopt? In the long run, firms succeed relative to their competitors if they possess sustainable competitive advantage in either of these two, subject to reaching some threshhold of adequacy in the other. In Exhibit 2, somogyi galliers (1987) provide examples of applications of information technology which are consistent with these two strategic stances, mapped against the particular enterprise activities to which they contribute. Another important consideration in positioning is competitive scope, or the breadth of the enterprises target markets within its industry,.

For developments along that path, see kaufmann 1966, kantrow 1980, pyburn 1981, parsons 1983, edp analyzer 1984a, 1984b, McFarlan 1984, benjamin et al 1984, wiseman macmillan 1984, ives learmonth 1984, cash konsynski 1985, porter millar 1985, keen 1986, king 1986). This first section outlines the basis of that theory. Strategic information systems theory will then be shown to be concerned with the use of information technology to support or sharpen an write enterprises competitive strategy. Competitive strategy is an enterprises plan for achieving sustainable competitive advantage over, or reducing the edge of, its adversaries. In Porters paper view, the performance of individual corporations is determined by the extent to which they cope with, and manipulate, the five key forces which make up the industry structure? The bargaining power of suppliers;? The bargaining power of buyer;? The threat of new entrants;? The threat of substitute products; and? Rivalry among existing firms.
An alternative interpretation of the term is that it is not necessary a particular is, but rather the combination of those parts of an organisations cluster of information systems which provide information into its strategic planning processes (Higgins vincze 1993. The functions involved include the gathering, maintenance and analysis of data concerning internal resources, and intelligence about competitors, suppliers, customers, government and other relevant organisations. A variety of interpretations of strategy exist, most of which have a great deal to do with competition between corporations. Chamberlins theory of monopolistic competition sees corporations as being heterogeneous, and competing on the basis of asset differences, such as technical knowledge, reputation, ability for teamwork, organisational culture and skills, and other invisible assets (Chamberlin 1933, Itami 1987). Competition therefore means cultivating unique strengths and capabilities, remote and defending them against imitation by other firms. Another alternative sees competition as a process linked to innovation in product, market, or technology (Schumpeter 1950). Porters Strategic Theory, the context within which sis theory emerged was the competitive strategy framework put forward by porter (1980, 1985 which was based on industrial organisation economics.
Origins, the role of Information Systems (IS) has developed during the years. The original conception was of automation of existing manual and pre-computer mechanical processes. This was quickly succeeded by the rationalisation and integration of systems. In both of these forms, is was regarded primarily as an operational support tool, and secondarily as a service to management. During the 1980s, an additional potential was discovered. It was found that, in some cases, information technology (IT) had been critical to the implementation of an organisations strategy. The dominant sense in which the term is used is that a strategic information system (SIS) is an information system which supports an organisation in fulfilling its business goals.

A number of weaknesses in the existing body of theory are identified, and suggestions made as to directions in which knowledge is management or may be progressing. Introduction, the topic of strategic information systems is concerned with systems which contribute significantly to the achievement of an organisations overall objectives. The body of knowledge is of recent origin and highly dynamic, and the area has an aura of excitement about. It is risky to attempt a historical exposition of such a recently emerged topic. On the other hand, the line of development which the conventional wisdom has followed is itself interesting and instructive.
This paper is prepared as an introduction to the literature, but embodies interpretation in both its structure and its expression, and should therefore be read with at least as critical a disposition as any other paper in the area. It may also be compared with other critical interpretations such as Swatman swatman (1992 galliers (1993) and Ciborra (1994). The notion and its origins are first discussed. The emergence of the key ideas is then traced. The process whereby strategic information systems come into being is assessed. Finally, areas of weakness are identified, and directions of current and future development suggested.

Abstract, during the last 15 years, an area has developed within the Information Systems discipline which is generally referred to as strategic information systems. It concerns itself with systems whose importance to the organisation extend beyond merely assisting it to perform its existing functions efficiently, or even just effectively. A strategic information system is instrumental in the organisations achievement of its competitive or other strategic objectives. This paper presents a critical summary of the literature, and is accompanied by an extensive reference list. It begins by tracing the development of contemporary theory about strategic uses of corporations internal information systems, primarily from Porters theories relating to competitive strategy. This leads to discussion of systems which transcend the boundaries of particular organisations and are associated with cooperation between them. The process whereby strategic information systems are created or identified is then examined.

The "new" science of complexity which describes emergence, adaptation and self-organization was established mainly by researchers of the sfi and is based on agents and computer simulations and includes multi-agent systems (MAS) which have become an important tool to study social and complex. Cas are still an active field of research. References edit daniel Durand (1979) la systémique, presses Universitaires de France ludwig von Bertalanffy (1968).

have the common goal to explain complex systems which consist of a large number of mutually interacting and interwoven parts. Cellular automata (ca neural networks (nn artificial intelligence (AI), and artificial life (ALife) are related fields, but they do not try to describe general complex systems. The best context to compare the different "C"-Theories about complex systems is historical, which emphasizes different tools and methodologies, from pure mathematics in the beginning to pure computer science now. Since the beginning of chaos theory when Edward Lorenz accidentally discovered a strange attractor with his computer, computers have become an indispensable source of information. One could not imagine the study of complex systems without computers today. Timeline edit 1960 cybernetics (W.

thinking has been developed to provide techniques for studying systems in holistic ways to supplement more traditional reductionistic methods. In this more recent tradition, systems theory is considered by some as a humanistic counterpart to the natural sciences. History edit, subjects like complexity, self-organization, connectionism and adaptive systems had already been studied in the 1940s and 1950s, in fields like cybernetics through researchers like. Norbert wiener, william Ross Ashby, john von neumann and heinz von foerster. They only lacked the right tools, and tackled complex systems with mathematics, pencil and paper. John von neumann discovered cellular automata and self-reproducing systems without computers, with only pencil and paper. Aleksandr lyapunov and, jules Henri poincaré worked on the foundations of chaos theory without any computer at all. All of the "C"-Theories below - cybernetics, catastrophe theory, chaos theory.
A system is composed of regularly interacting or interdependent groups of activities/parts that form a whole. Part of systems theory, system dynamics is a method for understanding the dynamic behavior of complex systems. The basis of the method is the recognition that the structure of any system - the many circular, interlocking, sometimes time-delayed relationships among its components - is often just as important in determining its behavior as the individual components themselves. Examples are chaos theory and social dynamics. Systems theory has also been developed within sociology. The most notable scientist in this area. Niklas Luhmann (see statement luhmann 1994).

Systems theory or general systems theory or systemics is an interdisciplinary field which studies systems as a whole. Systems theory was founded. Ludwig von Bertalanffy, william Ross Ashby and others between the 1940s and the 1970s on principles from physics, biology and engineering and later grew into numerous fields including philosophy, sociology, organizational theory, management, fuller psychotherapy (within family systems therapy) and economics among others. Cybernetics is a closely related field. In recent times complex systems has increasingly been used as a synonym. Contents, overview edit, systems theory focuses on complexity and interdependence.
