Difference between Agile and Waterfall project methodologies

 By: Abhishek Narula


Waterfall methodology

The waterfall method is a traditional project management approach that uses sequential phases to define, build, test, and release project deliverable. Each phase is completed and approved before the team moves on to the next phase. The project can't move backwards to previous phases.

Agile methodology

Agile is an umbrella term covering several newer project management approaches that use iterative work cycles called sprints. Each sprint uses 'mini-phases' to define, build, test, and release the project deliverable.

Difference between Agile and Waterfall

1) Methodology of Agile and Waterfall

Both Agile and Waterfall are two of the most prominent software development methodologies used for ERP projects to deliver high value products in the least time possible. However, despite a common goal, they use different approaches to get the projects done. While Agile follows an incremental approach to get things done, Waterfall uses a sequential design process.

2) Approach in Agile and Waterfall

Both are viable methods used in project management but in different ways. Waterfall uses a traditional approach which can be rigid at times and where the whole development process is divided into a series of events starting from conception and all the way through to production. Agile, on the other hand, is newer than Waterfall and uses an incremental approach to lean development.

3) Scope of Agile and Waterfall

Waterfall is more like plan-driven which see analysis, design, coding, implementation, and testing as different phases of a software development project. It works well when scope of the project is known beforehand, but it limits changes thereby restricting adaptability. Agile, as a modern approach, is open to changes comes at a price of course, but it works well when scope of the project is unknown.
