Waterfall model

In the waterfall model the process in carried in phases. The output of one phase in the waterfall model is the input to the other phase. There is a sequential and linear flow amongst the process. There are standards set for the output of each process. If one output is wrong it disturbs the entire model.

With the help of the waterfall model one can easily measure the progress of the current project which is carried on. As, the model is a diagrammatic representation it is very easy to trace the output and the logical content of the project. The following are the phases of the waterfall model:

1) Preliminary Investigation

2)Requirement analysis

3)System Design

4)System Coding

5)System Testing

6)Implementation and Evaluation

7)Maintainable

hello sir,
my name is nithin i am having a small doubt if possible can u plz clarify my doubt plz. that is:-

Discuss the extent to which a fully formal process should be used, as opposed to a less formal one. Since, again, Mr. Owen is not familiar with the various approaches; you should include a description of the stages of a system life cycle (Waterfall methods).
In your considerations of System life cycle consider the following questions:

1.1. Explain the strength and weaknesses of using a waterfall or modified waterfall approach in this case.

And
1.2. Would it make sense to try one of the newer approaches such as the UP (Object oriented approach) or Extreme programming or Prototype? What prerequisites would be required to adopt a newer approach? If you were to recommend UP or Extreme programming or Prototype approach, what would include in each phase of the methodology.


plz send me the answer to putta.nithin@gmail.com or nithin.putta@yahoo.in


plz sir.
