If you will think regarding s/w development life cycle , you will find various models are available.Among them v model water fall model are there. For different type of project different type of models are necessary. Some extent you can say V model is better. In v model simultaneously you can validate and varify. you can write code as well as you can test. but in case of water fall model you can not do such type of thing. in water fall model once you can do means you can not go back.

Yes V model is better than waterfall model.

In Waterfall model only after coding the testing starts whereas in V model  coding and testing  happens simultaneously So it is Cost Efffective.

V-Model

Testing	Phase
Unit	Low Level Design
Integration	High Level Design
System	SRS
UAT	Business Requirements

hiin v model bugs are detected at each stage and rectified but in waterfall model bugs tend to accumulate and testing effort required is more for the same app.

It is an enforced disciplined approach.(systamatic approach)

See... in Water fall model If client is not clear with requirement, software development is difficult.

Unless one phase is completed the next phase is not started.

Every model has advantages and at same time Disadvantages too.

So we cant say that which one is better, that depends upon the Requirement of the Client.

hai!

v model is better than water fall model. because testing is done only in testing phasein waterfall model.but in v-model finding defects starts in each phase. so we decrease the amount of defects.testing is done in each phase.so expected defects will be founded easily. so v-model is better than water-fall model.
