will be used. A system proposal is the deliverable of this phase. The design phase decides how the system will operate. The final stage is the implementation phase, during which the system is actually built or purchased in the case of packaged software design. The system development life cycle (SDLC) is the process of understanding how information system can support business needs, designing the system, building it, and delivering it to users. The system analyst plays a key role in information
