In this chapter, we complete our systems development study by discussing and illustrating the remaining phases of systems development, the systems design, implementation, and operation phases. As with Chapter 6, one goal is to highlight the technology that will help us achieve systems development objectives as we conduct systems selection and systems design. For example, we consider the software and hardware testing that may be necessary during the systems selection process. We need always to keep in mind that a major purpose for undertaking systems development is to leverage existing technology to provide competitive advantage to the organization. We also see the aspects of these systems development steps that are most affected by the implementation of enterprise systems and e-business systems.
