The waterfall Project Management model is a skeleton for system development. It advances consecutively through a succession of phases, preliminarily with system feasibility analysis and concluding up to system release and maintenance.
Advantage of waterfall model : It is simple and easy to use. Dis Advantage of waterfall model : no user feedbacks are taken.
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.
All industries are using the waterfall model for software development.
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.
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.
Advantage of waterfall model : It is simple and easy to use. Dis Advantage of waterfall model : no user feedbacks are taken.
A waterfall model is a process that was used to develop and manufacture a product before computers became so commonplace. Because it was too cost prohibitive to make changes after the fact, a company used a waterfall model to develop their product. The stages of a waterfall modes are: Conceive, Design, Implement, Test, Deliver.
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 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.

Waterfall is a system development life cycle
The phases in the waterfall model are in Iswr and overlapped is true.
