Advantage of waterfall model : It is simple and easy to use. Dis Advantage of waterfall model : no user feedbacks are taken.
There are many advantages of using prototype model over waterfall model . Some of the advantages are: 1) Excellent for gathering and refining requirements. 2) Useful for assessing and reducing risks.
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.
The waterfall model is the oldest paradigm for software engeneering. However , over the past two decades,criticism of this process model has caused even ardent supporters to question its efficiency.The waterfall model, sometimes called the classic life cycle, suggests a systematic, sequential approaches to software development.
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 ?
I will try to answer this quickly as I don't have much time. As the name suggests, the waterfall model follows the path of an waterfall. It starts in the first stage of orientation, and ends at the release. It can only go one way (to the end goal) and the stages are very strict (you cant go back to a earlier stage). The Spiral model understands that reality doesn't always follow theory, and that an project should be designed to follow that reality. There are multiple prototypes released, and phases can be repeated until the desired result is reached (hence the spiral). The iterative model combines those two, making (IMHO) the waterfall model more ready for the real world. You should try googling yourself, I found lots of info about the differences in this article about the advantages of the waterfall model: http://www.waterfall-model.com/the-waterfall-model-avantages-and-disadvantages
Linear sequential model is also called as classic life cycle method, which is also known as waterfall model =>this waterfall model in software process model involes five stages 1. communication 2.planning 3.modeling 4.construction 5.deployment
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.
