what is advantages and disadvantages of the Waterfall Model and V-Model ?..

Answer / ramyab.mca@gmail.com

Hai...

WaterFall Model advantages:
It is a linear sequestial model
It is very simple model to implement
It is the first model.
It needs very few resources to implement
Disadvantages:
In this model there is no back tracking.
For example if any error occured an any
stage of software development,it cann't be
corrected in that build.

V-Model advantages:
It is also called as verification and
validation Model.
This means the verification and validation
will be done side by side.
It emphasies the strict process flow to
develop a quality product.
The errors occured in any pahse will be
corrected in that phase itself.
V-Model disadvantages:
It needs lot of resources and money.
It needs an established process to
implement.
It can be implemented by only some big
companies.

K,Byeee..
