Chapter 1: Information Systems, Organizations, and Integration
A Model of Information Systems in Organizations
Now that we have defined the key terms-information system, organization, and integration-we will combine them into a model of information systems in organizations that will become a roadmap for the rest of the book. Figure 1-4 represents information systems in organizations. As you can see, the figure combines the representation of information system (Figure 1-1) with the representation of organization and environment (Figure 1-3).In Figure 1-4, information systems link IT resources and organizational processes, as is also shown in Figure 1-1. This time, however, the processes and, as a result, the information systems are represented hierarchically to indicate different levels of managerial control and different types of information systems used to support these control levels.
Part of the IT resources resides outside the organizational boundary in the bottom of Figure 1-4. This is to reflect the fact that organizations are increasingly relying on IT resources that are not directly in their control such as public data resources, outsourced services, and the Internet.
Pit for the Book
The book comprises four parts: An Introduction to Enterprise Systems, A New Environment for Enterprise Systems, Building Enterprise Systems, and Extending Enterprise Systems.
In the present part, An Introduction to Enterprise Systems, the reader is provided with an historical context on the use of information systems in organizations as well as a discussion of the challenges facing organizations as they move toward integrating these systems. Following this introductory chapter, the second chapter in this section describes how modern organizations developed through the later part of the twentieth century, the rapid advancement of information technologies, and the fragmented nature of information systems in most organizational settings. The third chapter discusses the challenge of integration in terms of the motivations for integration, the common obstacles to achieving integrated systems, and some of the actual benefits of integrated systems.
The second part, A New Environment for Enterprise Systems, introduces the reader to enterprisewide integrated systems through an examination of each of the components that comprise them. The first chapter in this section defines organizational processes and describes how they interact to create chains of activity both inside and outside of organizations. The next chapter discusses how information technologies are arrayed as increasingly distributed resources within organizations. The reader is introduced to contemporary paradigms in distributed component architectures and client-server technologies. The third chapter in this section provides an introduction to database technologies that form the foundation for enterprise systems. The section concludes with a chapter that outlines the typical architecture of an enterprise system.
The third part, Building Enterprise Systems, shows the reader the processes through which organizations plan for, design, deploy, and operate enterprise systems. The first chapter in this section provides an overview of the enterprise system implementation life cycle and then focuses on the project initiation phase, including sourcing and vendor selection strategies, deployment options, and the establishment of the project charter. The following chapter covers the next two phases of enterprise system implementation: planning and design. Here, the reader is introduced to implementation project management as well as the various tools and methodologies available during the planning and design phases. The chapter also discusses enterprise modeling, including techniques for defining enterprise structure and the implications for reinventing or reengineering the organization. The next chapter in this section provides a step-by-step description of the realization of enterprise systems, beginning with customizing for different organizational structures and defining companyspecific objects, continuing with populating databases, building interfaces with the legacy systems, and defining customized reports, and concluding with testing and end-user acceptance. The chapter also covers the often neglected, but critical, topic of enterprise systems maintenance, including discussion of administration, metrics and tuning, training, and quality assurance. The section concludes with a chapter on people in enterprise systems. This chapter describes changing roles in the information systems area as well as other areas within the enterprise, discusses the various career paths that appear most promising, and describes the influence of gurus and mentors, executive sponsorship, and team-based structures in enterprise systems.
In the final part, Extending Enterprise Systems, the reader gets a glimpse of the many directions in which enterprise systems are being extended within organizations. The first chapter in this theme covers backward integration, including a discussion of extended supply chain management, procurement systems, and other interorganizational systems. The next chapter focuses on forward integration and the demand chain, with a discussion of Internet-enabled enterprise systems, customer asset management, sales force automation, and channel management systems. The final chapter discusses extending enterprise systems to support managers and executives through decision analysis tools, executive information systems, and data warehouses.
One might question the value of placing such an emphasis on a single class of information systems-enterprise systems. What is so special about them? Why do they merit such close examination?
It is our claim that the study of enterprise systems is both intrinsically and extrinsically valuable. Intrinsically, enterprise systems are worth studying because they are at the core of organizational computing. Unlike peripheral systems such as office automation software in most companies, enterprise systems inform the critical processes that organizations depend on for their success. Furthermore, enterprise systems by their very design have the broadest reach of all organizational information systems-they are used by every major functional area and at all levels of the enterprise.
Extrinsically, enterprise systems are worth studying because they represent a fundamental shift in the way that most organizations use information systems. Enterprise systems are a broad phenomenon; no longer are they being deployed solely in extremely large companies, nor are they being used just in certain industries.
Because of their high degree of complexity and the fact that organizations are increasingly dependent on the smooth operation of these systems for their success, the sophisticated skills needed to implement and manage enterprise systems are among the most sought after among computing professionals today...
