Waterfall Methodology:

• Sequential Process: Waterfall is a linear and sequential approach. Each phase must be completed before the next one begins.
• Stages: Typical stages include Requirements, Design, Implementation, Testing, and Maintenance.
• Example: Building a house. You complete the foundation before starting the walls, then the roof, and so on. You can’t go back to change the foundation once the walls are up.

Agile Methodology:

• Iterative Process: Agile is iterative and flexible. Work is divided into small chunks called sprints, usually lasting 2-4 weeks.
• Continuous Feedback: Regular feedback and adjustments are made throughout the project.
• Example: Developing a mobile app. You create a basic version with core features, get feedback, and then add more features and improvements in subsequent sprints. You can make changes at any point based on feedback.

Here are the differences between Agile and Waterfall methodologies in simple terms:
