Waterfall vs Agile Development | Software Development Life Cycle Models

Waterfall and Agile are the two most used Software Development Development Life Cycle (SDLC) Models. Hence it is very common to face a dilemma – waterfall model or agile model, which one to choose and why. To shower light upon this waterfall vs agile model, let us see a detailed discussion of their differences.

Waterfall Model

The waterfall model is a famous and good version of SDLC(System Development Life Cycle) for software engineering. The waterfall model is a linear and sequential model, which means that a development phase cannot begin until the previous phase is completed. We cannot overlap phases in the waterfall model.

Agile Model

Agile model is a combination of iterative and incremental models, that is, it is made up of iterative and incremental models.

In Agile model, the focus is given to process adaptability and customer satisfaction.

Difference between Waterfall vs Agile Development Model

Aspect	Agile	Waterfall
Life Cycle	It is a continuous iteration life cycle model to develop and test a software product.	It is a linear sequential model to develop and test a software product.
Process	In this The entire process of development is divided into sprints	The software development process is broken down into different phases.
Flexibility	Agile development model is flexible to make changes at any point of time (or at any stage of development process) .	In Waterfall model to make changes after one phase is difficult and costly.
client involvement	Continuous client Interaction and feedback	There is very little client involvement and very little feedback is taken.
Delivery Time	Its delivery time is very short and functional software is available very quickly.	Its delivery time is very long, the entire project must be completed before delivery.
