Waterfall Methodology

What is Waterfall Methodology?

The waterfall methodology is a linear and sequential approach to project management, where each phase must be completed before the next one begins. This approach is often used in software development, engineering, and construction projects, where changes to completed phases are difficult. The waterfall model is structured in stages such as requirements, design, implementation, testing, and maintenance.

Stages of Waterfall Methodology

• Requirements: Gathering detailed project requirements before development begins.
• Design: Creating the architecture and detailed design based on the requirements.
• Implementation: Developing the actual product or system according to the design.
