  • Today, no one would dispute that information technology has become the backbone of commerce. It underpins the operations of individual companies, ties together far-flung supply chains, and, increasingly, links businesses to the customers they serve. Hardly a dollar or a euro changes hands anymore without the aid of computer systems.
  • Our exploration of emergent social structures across domains of human activity and experience leads to an over-arching conclusion: as an historical trend, dominant functions and processes in the Information Age are increasingly organized around networks. Networks constitute the new social morphology of our societies, and the diffusion of networking logic substantially modifies the operation and outcomes in processes of production, experience, power, and culture. While the networking form of social organization has existed in other times and spaces, the new information technology paradigm provides the material basis for its pervasive expansion throughout the entire social structure.

  • The coordination of information technology management presents a challenge to firms with dispersed IT practices. Decentralization may bring flexibility and fast response to changing business needs, as well as other benefits, but decentralization also makes systems integration difficult, presents a barrier to standardization, and acts as a disincentive toward achieving economies of scale. As a result, there is a need to balance the decentralization of IT management to business units with some centralized planning for technology, data, and human resources.
Here we explore three major mechanisms for facilitating inter-unit coordination of IT management: structural design approaches, functional coordination modes, and computer-based communication systems. We define these various mechanisms and their interrelationships, and we discuss the relative costs and benefits associated with alternative coordination approaches.
To illustrate the cost-benefit tradeoffs of coordination approaches, we present a case study in which computer-based communication systems were used to support team-based coordination of IT management across dispersed business units. Our analysis reveals possibilities for future approaches to IT coordination in large, dispersed organizations.

  • During the Cold War a new conceptual framework took hold of U.S. defense thinking in an attempt to reduce unpredictability. The advent of the computer and its incorporation into the military as a data processor and numbers cruncher during World War II led commanders to believe that the uncertainty and unpredictability that defined chaos on the battlefield could be overcome through information technology. Chaos was seen as an information deficiency rather than an inescapable element of warfare. Massive amounts of data were collected and processed in an attempt to reach battlefield clarity and subordinate the theatre of war. The new term "command and control" described the belief that commanders could issue orders, receive new information through feedback of their technology system and adjust subsequent orders accordingly.

  • Tracking the individual learning curves of the major technologies that comprise the infrastructure of information technology provides a more detailed account of the present and future state-of-the art of the technologies underlying convergence. The base technologies of digital electronics, general-purpose computer architectures, software and interaction are mature and provide solid foundations for computer science. The upper technologies of knowledge representation and acquisition, autonomy and sociality, support product innovation and provide the beginnings of foundations for knowledge science. Well's dream of a world brain making available all of human knowledge is well on its way to realization and it is in the representation, acquisition, and access and effective application of that knowledge that the commercial potential and socio-economic impact of convergence lies.
  • It is clear that even though information technology (I/T) has evolved from its traditional orientation of administrative support toward a more strategic role within an organization, there is still a glaring lack of fundamental frameworks within which to understand the potential of I/T for tomorrow's organizations. In this paper, we develop a model for conceptualizing and directing the emerging area of strategic management of information technology. This model, termed the Strategic Alignment Model, defined in terms of four fundamental domains of strategic choice: business strategy, information technology strategy, organizational infrastructure and processes, and information technology infrastructure and processes-each with its own underlying dimensions.
  • The strategic role of information systems in “extending” the enterprise is examined. A number of issues emerge as essential considerations in the strategic alignment of the investment in information technology and business strategy. Information technologies transform organizational boundaries, interorganizational relations, and marketplace competitive and cooperative practice. The paper presents a framework of strategic control that guides the planning and execution of these investments in information technology for business transformation, seeking increased understanding and influence. Emerging information technologies change the limits of what is possible in the leverage of strategic control through transformation of boundaries, relations, and markets.

  • Enterprise architectures are required to support and maximize the efforts of virtual teams within decentralized organizations. Vendor products exist today to start evolving towards a standards-based multi-vendor architecture. The underlying networking technology, 802.3/Ethemet, is robust and will provide for a cost-effective investment that will last for many years to come. Complimentary LAN technologies are already available to ensure transparent growth of networked systems. Combining human resources with information technology will be the key differentiating factor for successful manufacturing enterprises in the 1990s.

  • When software applications became larger and larger, people such as Shaw and Garlan coined the term software architecture. This notion of architecture deals with the key design principles underlying software artefacts. In the 1980s and 1990s, people became aware that the development of information technology (IT) should be done in conjunction with the development of the context in which it was used. This led to the identification of the so-called business/IT alignment problem. Solving the business/IT alignment problem requires enterprises to align human, organizational, informational, and technological aspects of systems. Quite early on, the term architecture was also introduced as a means to further alignment, and thus analyzes and solves business?IT alignment problems, Recently, the awareness emerged that alignment between business an IT is not enough, there are many more aspects in the enterprise in need of alignment. This has led to the use of the term architecture at the enterprise level: enterprise architecture.

  • The strategic use of information technology (I/T) is now and has been a fundamental issue for every business. In essence, I/T can alter the basic nature of an industry. The effective and efficient utilization of information technology requires the alignment of the I/T strategies with the business strategies, something that was not done successfully in the past with traditional approaches. New methods and approaches are now available. The strategic alignment framework applies the Strategic Alignment Model to reflect the view that business success depends on the linkage of business strategy, information technology strategy, organizational infrastructure and processes, and I/T infrastructure and processes... We [have looked] at why it may not be sufficient to work on any one of these areas in isolation or to only harmonize business strategy and information technology. One reason is that, often, too much attention is placed on technology, rather than business, management, and organizational issues. The objective is to build an organizational structure and set of business processes that reflect the interdependence of enterprise strategy and information technology capabilities. The attention paid to the linkage of information technology to the enterprise can significantly affect the competitiveness and efficiency of the business. The essential issue is how information technology can enable the achievement of competitive and strategic advantage for the enterprise.

  • Standing here before a mural of your revolution, I want to talk about a very different revolution that is taking place right now, quietly sweeping the globe without bloodshed or conflict. Its effects are peaceful, but they will fundamentally alter our world, shatter old assumptions, and reshape our lives. It's easy to underestimate because it's not accompanied by banners or fanfare. It's been called the technological or information revolution, and as its emblem, one might take the tiny silicon chip, no bigger than a fingerprint. One of these chips has more computing power than a roomful of old-style computers. As part of an exchange program, we now have an exhibition touring your country that shows how information technology is transforming our lives -- replacing manual labor with robots, forecasting weather for farmers, or mapping the genetic code of DNA for medical researchers. These microcomputers today aid the design of everything from houses to ears to spacecraft; they even design better and faster computers. They can translate English into Russian or enable the blind to read or help Michael Jackson produce on one synthesizer the sounds of a whole orchestra. Linked by a network of satellites and fiber-optic cables, one individual with a desktop computer and a telephone commands resources unavailable to the largest governments just a few years ago.
  • Our system is not fit for purpose. It's inadequate in terms of its scope, it's inadequate in terms of its information technology, leadership, management systems and processes.
  • Now let me pull out so we’re clear about the problem we all face and how we got here. The attacks against us in Rappler began 5 years ago when we demanded an end to impunity on two fronts: Duterte’s drug war and Mark Zuckerberg’s Facebook. Today, it has only gotten worse – and Silicon Valley’s sins came home to roost in the United States on January 6 with mob violence on Capitol Hill. What happens on social media doesn’t stay on social media. Online violence is real world violence. Social media is a deadly game for power and money, what Shoshana Zuboff calls surveillance capitalism, extracting our private lives for outsized corporate gain. Our personal experiences are sucked into a database, organized by AI, then sold to the highest bidder. Highly profitable micro-targeting operations are engineered to structurally undermine human will – a behavior modification system in which we are Pavlov’s dogs, experimented on in real time with disastrous consequences in countries like mine, Myanmar, India, Sri Lanka and so many more. These destructive corporations have siphoned money away from news groups and now pose a foundational threat to markets and elections. Facebook is the world’s largest distributor of news, and yet studies have shown that lies laced with anger and hate spread faster and further than facts on social media. These American companies controlling our global information ecosystem are biased against facts, biased against journalists. They are – by design – dividing us and radicalizing us. Without facts, you can’t have truth. Without truth, you can’t have trust. Without trust, we have no shared reality, no democracy, and it becomes impossible to deal with our world’s existential problems: climate, coronavirus, the battle for truth.
  • The Enterprise Architecture is the explicit description of the current and desired relationships among business and management process and information technology. It describes the "target" situation which the agency wishes to create and maintain by managing its IT portfolio.
    The documentation of the Enterprise Architecture should include a discussion of principles and goals. For example, the agency's overall management environment, including the balance between centralization and decentralization and the pace of change within the agency, should be clearly understood when developing the Enterprise Architecture. Within that environment, principles and goals set direction on such issues as the promotion of interoperability, open systems, public access, end-user satisfaction, and security.
  • Assessing the value of information technology (IT) has never been easy. Delayed benefits, unintended uses, business changes, and hidden support costs inhibit meaningful evaluation of individual TT investments. This was true when most investments were focused on the support of a single business process or functional area. It is even more true as business executives ponder implementations of shared technologies like data warehouses and networks, replacement of large legacy systems, and reskilling of the IT staff. Although firms introduce some systems to reduce costs and can evaluate them in terms of their success in doing so, they want many IT initiatives to support a firm's objectives. The value of these initiatives rest in their contributions to a firm's competitiveness, which is often non quantifiable and uncertain.

  • A fundamental change is taking place in the nature and application of technology in business, a change with profound and far-reaching implications for companies of every size and shape. A multimillion dollar research program conducted by the DMR Group, Inc., studied more than 4,500 organizations in North America, Europe, and the Far East to investigate the nature and impact of changes in technology. The synthesis and analysis of this information indicate that information technology is going through its first paradigm shift. Driven by the demands of the competitive business environment and profound changes in the nature of computers, the information age is evolving into a second era. Computing platforms in most organizations today are not able to deliver the goods for corporate rebirth. It is only through open network computing that the open networked client/server enterprise can be achieved. In nontechnical language this book shows managers and professionals how to take immediate action for the short-term benefits of the new technology while positioning their organizations for long-term growth and transformation...

  • In the last few years, an information resources management concept has emerged as a focus of managing information activities. Although lacking a concise or universal definition, the IRM concept has become a framework for planning more responsive and coordinated information management organization structures throughout Government and the private sector. In brief, IRM is viewed as an integration of management responsibilities for the control of information-related activities and related processes. It includes the planning and management of information collection, use, and dissemination as well as management of information technology.
  • The concept of enterprise architecture emerged in the mid-1980s as a means for optimizing integration and interoperability across organizations. In the early 1990s, GAO research of successful public and private sector organizations led it to identify enterprise architecture as a critical success factor for agencies that are attempting to modernize their information technology (IT) environments. Since then, GAO has repeatedly identified the lack of an enterprise architecture as a key management weakness in major modernization programs at a number of federal agencies. It has also collaborated with the Office of Management and Budget (OMB) and the federal Chief Information Officers (CIO) Council to develop architecture guidance. In 2002, OMB began developing the Federal Enterprise Architecture (FEA), an initiative intended to guide and constrain federal agencies’ enterprise architectures and IT investments.
  • The objective of Computer-Integrated Manufacturing (CIM) is the appropriate integration of enterprise operations by means of efficient information exchange within the enterprise with the help of Information Technology (IT). Integration includes the physical and logical connection of processes by means of data communications technology operating to specified standards, but also the integration of enterprise functions as welt as enterprise information. Generalized models and an open systems architecture are required to reduce the system complexity to a manageable level. They are used to identify the principal components, processes, constraints and information sources used to describe a manufacturing enterprise progressing towards CIM. In this paper, the basic concepts of an open-systems architecture for CIM called CIM-OSA are presented. The function view of the CIM-OSA modelling framework is discussed. CIM-OSA provides a unique set of advanced features to model functionality and behaviour of CIM systems at three distinct levels (requirements definition, design specification and implementation description).
