System Development Life Cycle The System Development Life Cycle (SDLC) is a process used to develop and maintain software and IT systems. It is a framework that defines the phases and activities involved in creating, deploying, and maintaining a system. The SDLC is used to ensure that a system is developed and deployed in a structured, efficient, and cost-effective manner. The SDLC has several phases, each with its own set of objectives and deliverables. The phases are typically divided into the following categories: planning, analysis, design, development, testing, deployment, and maintenance. The planning phase is the first phase of the SDLC. During this phase, the objectives and requirements of the system are defined and a project plan is created. This phase also includes a feasibility study to determine if the proposed system is viable and cost-effective. The analysis phase is the second phase of the SDLC. During this phase, the system requirements are gathered and analyzed. This p
