Detailed explanation-1: -Waterfall is the oldest and most straightforward of the structured SDLC methodologies-finish one phase, then move on to the next. No going back. Each stage relies on information from the previous stage and has its own project plan. Waterfall is easy to understand and simple to manage.

Detailed explanation-2: -Waterfall Regardless, Waterfall is widely considered the oldest of the structured SDLC methodologies. It’s also a very straightforward approach: finish one phase, then move on to the next.

Detailed explanation-3: -The waterfall model is a linear, sequential approach to the software development lifecycle (SDLC) that is popular in software engineering and product development. The waterfall model uses a logical progression of SDLC steps for a project, similar to the direction water flows over the edge of a cliff.

Detailed explanation-4: -Requirements: The first phase involves understanding what needs to design and what is its function, purpose, etc. Here, the specifications of the input and output or the final product are studied and marked.

Detailed explanation-5: -Stage 1: Project Planning The first stage of SDLC is all about “What do we want?” Project planning is a vital role in the software delivery lifecycle since this is the part where the team estimates the cost and defines the requirements of the new software.
