How Information Technology Is Conquering the World focuses on the interface between the technologies and the real world in order to explore not only where these technologies have their advantages, but also where their limitations become apparent. The difficulty of introducing a new technology is emphasized with the practical goal of enabling readers to use technology to full advantage. This book is useful for those involved in, affected by, or interested in the technology; for students taking an introductory course in computing; and for managers and others who are interested in seeing how this rapidly evolving technology will affect their lives, jobs, and businesses now and in the future.

PurposeTo show that developing proprietary software is the best alternative for many small and medium‐sized enterprises (SMEs). Full control of the software makes it possible to remain flexible and dynamic, and to conform to the need of the customer at any time.Design/methodology/approachThe approach is case based.FindingsModern development tools make in‐house development feasible. Costs are often comparable to that of using standard ERP systems. In‐house development does not need to encompass all functions, as it is easy to integrate off‐the‐shelf systems with proprietary development. Being in control of core software is important for the day‐to‐day activities of a company, and also for gaining a strategic advantage.Practical implicationsIn‐house development will be most useful for niche companies. Further, SMEs will have an advantage as they more easily can integrate standard systems with proprietary software.Originality/valueMany managers have excluded the possibility of developing their own software, based on experience with time consuming and expensive projects in the past. Thus, implementing standard ERP systems is often viewed as the only solution. However, these systems may impose a rigid structure on a company, threatening the dynamic nature of many SMEs. We show that many companies have a better alternative.

The Telecommunications Act of 1996 opened competition in the telecommunications market in the U.S. and forced the incumbent telecommunications companies to open both their physical and logical infrastructure for Competitive Local Exchange Carriers (CLECs). In this case study we focus on the problems that face a CLEC with regard to designing an information system and getting a back office system, called an Operations Support Systems (OSS), operational in a highly competitive, complex, fast-paced market in a compressed time frame when a change in a critical telecommunications network component, namely the central office switch, is made after 75% of the system implementation was completed. This case deals with the factors that led to this change in central office switches, its impact on the IT department, its impact on the company, and the alternatives considered by the IT department as possible solutions to the many problems created by this change.
