Main Difference between Agile & Waterfall Methodologies

Waterfall Agile
In waterfall model once a step has been completed, developers can’t go back to a previous stage and make changes. The Agile methodology allows for changes to be made after the initial planning. Re-writes to the program, as the client decides to make changes, are expected. you can make changes on next sprint
Waterfall methodology relies heavily on initial requirements. However, if these requirements are faulty in any manner, the project is doomed. The Agile methodology total deliverable is divided into some sprints, if there is any backlogs that can come in next sprint.
If there is any change needs to be made, the project has to start from the beginning with all new code. Agile methodology allows you to make changes, it’s easier to add features that will keep you up to date with the latest developments
Whole product is only tested at the end. It may fail during integration testing then the product will not be delivered on time or even fail. The testing at the end of each sprint ensures that the bugs are caught and taken care of in the development cycle. They won’t be found at the end.
If the client realizes that they need more than they initially thought, and demand change, the project will come in late and impact budget. Because the products are tested so thoroughly with Agile, the product could be launched at the end of any cycle. As a result, it’s more likely to reach its launch date.
