What is traditional system development lifecycle?

The traditional System Development Lifecycle (SDLC) is a structured approach to software development that outlines a series of phases for building and maintaining systems. It typically includes stages such as requirements gathering, system design, implementation, testing, deployment, and maintenance. This linear model emphasizes thorough documentation and planning, allowing for clear project milestones and accountability. Common methodologies within this framework include the Waterfall model, which advocates for completing one phase before moving on to the next.
