The Software Development Life Cycle (SDLC) is a structured process used for developing software applications. It consists of several phases, including planning, analysis, design, implementation, testing, deployment, and maintenance. Each phase has specific tasks and deliverables, ensuring that the software meets user requirements and quality standards. By following the SDLC, teams can manage project timelines, resources, and risks effectively. This systematic approach helps in identifying issues early, improving collaboration among team members, and ensuring that the final product is reliable and functional. Overall, the SDLC is essential for successful software development projects.
