The waterfall model derives its name due to the cascading effect from one phase to the other as is illustrated in Figure In this model each phase well defined starting and ending point, with identifiable deliveries to the next phase.
Note that this model is sometimes referred to as the linear sequential model or the software life cycle.
Yes, waterfall model is non applicable in some areas. Reason being that we can not go back to the previous stage if we missed something , we have to restart the process.
In waterfall model, once we come out of the phase, there is no chance of modifying it again. This is one of the major drawback for waterfall model.
Waterfall is one of the software development life cycle model. Waterfall model has five stages.
Expalin different between waterfall model and prototyping model ? Expalin different between waterfall model and prototyping model ?
Modified waterfall model verified and validate the user requirements for every phase. Meanwhile, waterfall did not, it only verify and validate user requirement at the end of the phase.
The testing phase consumes the maximum effort in waterfall model.

The waterfall model is the oldest and most widely used model in the field of software development. There are certain advantages of the waterfall model, which causes it to be the most widely used model as yet. Some of them can be listed as under.Needless to mention, it is a linear model and of course, linear models are the most simple to be implemented.The amount of resources required to implement this model is minimal.One great advantage of the waterfall model is that documentation is produced at every stage of the waterfall model development. This makes the understanding of the product designing procedure simpler.After every major stage of software coding, testing is done to check the correct running of the code.
Waterfall is one of the software development life cycle model. Waterfall model has five stages.
Advantage of waterfall model : It is simple and easy to use. Dis Advantage of waterfall model : no user feedbacks are taken.
A "V-model" refers to an entire development process where the design takes a "top down" approach and the testing and implementation starts from the "bottom up".

the waterfall model gives us prototyping , and spirl model gives us product , so the set of the waterfall accommodat in the spirl to gives us this product.
1.spiral model can be accommodate in prototyping and waterfall model. it is a model of iterative process as prototyping and also a systematic approach to solve a problem as in waterfall model. 2. spiral model take problem as a series of step to solve a problem as in waterfall, and take the contribution of users or customers in each phase as in prototyping model.
