Systems analysis and design is the process of creating and maintaining information systems. The classic methodology used in systems analysis and design to develop information systems is called the systems development life cycle (SDLC).
1. System definition
2. Requirements analysis
3. Component design
5. System maintenance
These steps, together with the business process that determines the need for the information system to be created and the users of that system, are shown in Figure F-6. Each step should result in one or more deliverables, such as documents, designs, prototypes, data models, database designs, Web screens, and so on.
