Agile Vs Waterfall

What is Agile Model?

The Agile Model is a flexible, iterative, and collaborative approach to software development. It breaks the work into small parts called sprints or iterations, usually lasting 1–4 weeks. After each sprint, a working piece of the software is delivered to the client for feedback and improvement.

What is Waterfall Model?

The Waterfall Model is a linear and structured approach to software development. Each phase must be completed fully before moving to the next one. There’s very little room to go back and make changes.

Let us now see the differences between the Agile and Waterfall models.

Differences -

Criteria	Agile Model	Waterfall Model
Approach	Iterative (Sprints) and Incremental	Phases wise and Linear
Flexibility	Highly flexible, changes are allowed during the development	Rigid, allowing changed in middle of development are difficult and costly
Testing	Done in every sprint	Done after the development phase
Delivery	Partial product delivered frequently	Fully developed product delivered at the end
Customer Involvement	Continuous feedback after every iteration	Only involved at the beginning and end of project
Best For	Projects with uncertain or evolving requirements	Projects with well-defined, fixed requirements
Risk	Lower, as issues are identified early	Higher, issues may be found late
Transparency	Gives transparency on the progress of the work to the customer	Customer would not be able to see the product until it is delivered completely
Feedback	Immediate user feedback would help to lower the risk of failure	User feedback cannot be given until the product is completely developed and delivered
Documentation	Documentation is not so important	Process and results would be well documented
