ISDP1: system methodologies-SYSTEMS DESIGN UNIT 3

1.0 INTRODUCTION While in systems analysis the focus is on identifying the needs of the organization, the emphasis of systems design is to develop a new system that helps to achieve the goals and objectives of the organization and overcomes some of the shortcomings and limitations of the existing system. If the problems are minor, only small modifications are required. On the other hand, major changes may be suggested by systems analysis. In these cases, major investments in additional hardware, software, and additional personnel may be necessary. Regardless of the complexity and scope of the new system, it is the purpose of systems design to develop the best possible system. 2.0 OBJECTIVES By the end of this unit, you should be able to: • Explain the process of interactive design • Outline the various design techniques in systems • Outline the various design considerations • Describe procedures design • Discuss system design alternatives
