The Software Development Lifecycle (SDLC) consists of six phases: requirement gathering and analysis, design, development/coding, testing, deployment, and maintenance/support. Each phase has specific goals, processes, involved personnel, and deliverables aimed at developing and maintaining software applications effectively. This structured approach ensures that software meets functional and non-functional requirements before being released to users.
