Difference between V-model and Waterfall model
Besides that V-model is the alternative to the waterfall model. There is some difference between these two models which are given below.
|
Aspect |
Waterfall model |
V-model |
|---|---|---|
|
Cost |
The cost of Waterfall model is low. |
V-model is expensive. |
|
Simplicity |
Simplicity of Waterfall model is simple. |
Simplicity of V-model is Intermediate. |
|
Flexibility |
Flexibility of Waterfall model is Rigid. |
Flexibility of V-model is Little flexible. |
|
Phases |
There is no way to return to the earlier phase. | There is no such constraint in V-model. |
|
Execution Process |
Waterfall model is a sequential execution process. | It is also a sequential execution process. |
|
Linear Movement of Steps |
Waterfall model’s steps move in a linear way. | V-model’s steps don’t move in linear way. |
|
Reusability |
Re-usability of Waterfall model is Limited. | V-model can be Re-use for some extent. |
|
User Involvement |
User involvement in Waterfall model is only in beginning. | User involvement in V-model is also only in beginning. |
|
Testing Activities Start |
In Waterfall model testing activities start after the development activities are over. | In V-model testing activities start with the first stage. |
|
Success Guarantee |
Guarantee of success through Waterfall model is low. | Guarantee of success through V-model is high. |
|
Process |
Waterfall model is a continuous process. | V-model is a simultaneous process. |
|
Defects |
Software made using Waterfall model, the number of defects are less in comparison of software made using V-model. | Software made using V-model, the number of defects are greater in comparison of software made using Waterfall model. |
|
Requirement Specification |
Requirement specification in Waterfall model is necessary in beginning. | Requirement specification in V-model is also necessary in beginning. |
|
Customer Involvement |
Less customer involvement. | More customer involvement as compared to waterfall model. |
|
Testing during Development |
It is not possible to test a software during its development. | There is possibility to test a software during its development. |
|
Identification of Defects |
Identification of defects is done in the testing phase. | Identification of defects can be done from the beginning. |
|
Debugging |
Debugging is done after the last phase. | Debugging can be done in between phases. |
|
Usage |
Waterfall model is less used now-a-days in software engineering. | V-model is widely used in software engineering. |
Difference between V-model and Waterfall model
In the software business, the Waterfall model and the V-Model are both highly popular development approaches. Both of these paradigms provide systematic assistance for the creation of apps. The primary distinction between the V-Model and the Waterfall Model is that the V-Model identifies flaws during the testing phase, whereas the Waterfall Model identifies flaws at the outset.
