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. |
