Advantages

if our Requirements are constant means there is no chance of changing of requirement means before going to Development we can freeze the requirements then it is a best model. and as it is the simplest model so if we will use this model then it is cost saving also

Disadvantages

If our Requirements are not constant means there is some chance of changing the requirements in between then it is not the better practice to use this one

Lastly keep one thing in mind that before going for this model WE SHOULD FREEZE THE REQUIREMENTS.....

hi friends

advantage: waterfall model is best suited if the user requirements are constant, by this one can know the exact  status of development.

disadvantage: for ever changing user requirements this model will not suit, one process starts only when the previous process comes to an end.

i would like to explain more precisely...In waterfall model the designing part will not begin as long as the analysis process is finished, and analysis process will not start as long as the requiremenst are not gathered. so if the user requirements change constatly then the development process can not move forward.

correct me if i am wrong

Have you all given a thought to the Testing Phase in the Waterfall model? In this model testing is done AFTER coding! How good do you think that is?? Any and all advantages are totally over powered by this Disadvantage!

* Waterfall model is mainly used in commercial projects like banking and finance.And banking projects earn more profit so companies prefer waterfall model.

*It is a simple and linear process.

Disadvantage

*As the name itself implies , water always falls from top to bottom, similarly in waterfall model the process is only top to bottom.If an error is seen in the previous step , you can't go back and correct it. It can be corrected only in operation and maintenance step.

• Advantages:
  
  As the Requirements are freezed a robust application can be built
• Disadvantages

           No scope of changing the requirements

           Design not tested, requirements are not tested, as a result their is a downward flow of bug, needs lot of rework
           Testing is done by the develpers

Advantages: it is a continuos flow model.

disadvantages: if any defect or bug found in the application it is very difficult to start from the beginning phase.
