A Study on the Effective Use of Information Technology in Business

With the advent of new information and telecommunication technologies brought about by microprocessors that are used in business world, we can see that many types of information systems that are truly useful in business world. First, we investigate in this paper, the trend of the introduction of information system to business activities. In business, the way of using information systems is concentrated on rationalization, cost reduction, automation, etc. We also find that many types of information systems have been built rapidly. Secondly, we study the use of information system from the strategic point of view. For obtaining and maintaining the competitive edge in business, information technology plays a vital role. Finally, we discuss the use of information technology in "reengineering", which is an innovation in business process. To use information technology in the future, business must understand that competitive strategy is indispensable for building information systems. Building information systems strategically means that business can get a powerful tool, and by using it, the business can obtain and keep its competitiveness. Moreover, to accomplish the effective successful reengineering, the use of information technology is an important factor. The use of information technology in reengineering is different from that used in the past. But using information technology according to the new idea, information technology will be a powerful tool for innovating the business process

Reverse Engineering of Computer-Based Navy Systems

The financial pressure to meet the need for change in computer-based systems through evolution rather than through revolution has spawned the discipline of reengineering. One driving factor of reengineering is that it is increasingly becoming the case that enhanced requirements placed on computer-based systems are overstressing the processing resources of the systems. Thus, the distribution of processing load over highly parallel and distributed hardware architectures has become part of the reengineering process for computer-based Navy systems. This paper presents an intermediate representation (IR) for capturing features of computer-based systems to enable reengineering for concurrency. A novel feature of the IR is that it incorporates the mission critical software architecture, a view that enables information to be captured at five levels of granularity: the element/program level, the task level, the module/class/package level, the method/procedure level, and the statement/instruction level. An approach to reverse engineering is presented, in which the IR is captured, and is analyzed to identify potential concurrency. Thus, the paper defines concurrency metrics to guide the reengineering tasks of identifying, enhancing, and assessing concurrency, and for performing partitioning and assignment. Concurrency metrics are defined at several tiers of the mission critical software architecture. In addition to contributing an approach to reverse engineering for computer-based systems, the paper also discusses a reverse engineering analysis toolset that constructs and displays the IR and the concurrency metrics for Ada programs. Additionally, the paper contains a discussion of the context of our reengineering efforts within the United States Navy, by describing two reengineering projects focused on sussystems of the AEGIS Weapon System

Developing Sustained Competitive Advantage: Business Process Reengineering versus Management of Information as a Resource

Information Technology induced Business Process Reengineering is being offered as a solution to organizations to achieve competitive advantage in an intensely competitive environment. However, just radical changes in business processes will not help an organization sustain competitive advantage as successful business process reengineering projects can be cloned by competing organizations, thereby negating the competitive advantage developed by any one organization. Instead, if an organization were to design and implement information systems for strategic management of information as a resource, then use of such systems can lead to sustainable competitive advantage. This paper presents the case for the use of an information system designed from the resource based perspective as a source of sustainablecompetitive advantage over business process reengineerin

Software-Architecture Recovery from Machine Code

In this paper, we present a tool, called Lego, which recovers object-oriented software architecture from stripped binaries. Lego takes a stripped binary as input, and uses information obtained from dynamic analysis to (i) group the functions in the binary into classes, and (ii) identify inheritance and composition relationships between the inferred classes. The information obtained by Lego can be used for reengineering legacy software, and for understanding the architecture of software systems that lack documentation and source code. Our experiments show that the class hierarchies recovered by Lego have a high degree of agreement---measured in terms of precision and recall---with the hierarchy defined in the source code

EXPLORING THE ANTECEDENTS TO INFORMATION SYSTEMS DISCONTINUITIES: A COMPARISON OF THREE CASE STUDIES

An unanswered question in information systems (IS) research is: What triggers organizations to undertake reengineering or replacement of a mission-critical information system? While the benefits of reengineering efforts and new system implementations are well-documented, these large scale discontinuous system-changes are costly and known to be risky. IS projects frequently fail. A great deal of research has focused on understanding how new system implementations can be successful, once the decision to move forward is made. Alternatively, this research examines the antecedents of undertaking that costly and risky discontinuous change, as well as the role of inertia that precipitates the undertaking. We conducted 37 semistructured interviews in three organizations. We explored the reasons for replacing or reengineering their mission-critical information systems. We employ three theoretical explanations of change as derived from the organization theory and strategy literatures to conduct a cross-case analysis. While in some case studies external environmental forces and internal strategy changes reveal themselves as antecedents, we found that across all three cases, inherent constraints in the system slowed and even stifled the adaptation and design of these systems. We draw on structural inertia organizational change theories to explain these antecedents and how the systems evolved into their current states

Is There a Theory of Reengineering?

Business process reengineering has allowed many businesses to achieve significant improvements in performance, yet it seems that the reengineering promise and progress has reached a plateau of its own and reengineering is poised to enter the second generation (Cypress 1994). The fist generation saw development of a number of methodologies that allowed the reengineering projects to follow structured paths. Although methodologies differ in details, most of thein emphasize (1) changes in organizational objectives from an internal to a customer- and market-oriented focus, usually in response to competitive pressures, (2) a corresponding reconfiguration of production methods, (3) new information technology-based systems to enable these changes, and (4) significant changes in supporting processes such as human resources (Davenport 1993; Hammer and Champy 1993; Guha, Kettinger and Teng 1994). As the next generation of reengineering efforts are undertaken some practitioners are predicting shifts from the “customer value chain” paradigm to the “wealth creation and wealth consumption” paradigm (Cypress 1994). Yet, there is not clear theoretical framework available to evaluate and compare these methodologies and choose the one best suited for reengineering projects under consideration
