SDLC V Model

SDLC V Model

In this model the process execution done in V shape manner.

It is also known as Verification and validation model. sdlc

It is the extension of waterfall model. sdlc

It follows similar actions, but adds more to it creating a parallel of steps, hence the name V-model. sdlc

For each development phase, there is a testing phase as well. sdlc

sdlc

Instead of the stages following a cascade effect, they swoop back up to potentially repeated part of the process. sdlc

After determining the requirements and making sure everyone agrees with and knows what to expect, the designing stage is broken down by system, architectural, and modular designs. sdlc

Testing is done after each to find any possible flaws hiding within the software. sdlc

Coding is completed and the testing stage can begin, but as in the same fashion as the design stage, the testing is broken down. sdlc

It consists of unit, integration, system, and acceptance. sdlc

This breakdown offers multiple trials for the product to give the most chance for issue correction before release, thus possibly pulling it back into the development stages. sdlc

Each testing phase corresponds with one of the development stages to give a more defined process. sdlc

The V-Model does take longer than the Waterfall Model and has many of the same downfalls, but it offers more chances to fix issues earlier on. sdlc

While it is definitely a detailed way to perfect a project, it limits the flexibility of fixing bugs later on. sdlc

In this model the next phase will only start when the previous phase developed and tested thoroughly. sdlc

In this model, there’re Verification phases on one side of the ‘V’ while the validations phases are on the other side. sdlc

The Coding Phase joins both sides of the Model. sdlc

Verification Phases of V Model Includes: sdlc

• Business Requirement Analysis. sdlc
• System Design. sdlc
• Architectural Design. sdlc
• Module Design. sdlc
• Coding Phase. sdlc

Validation Phases of V Model Includes: sdlc

• Unit Testing. sdlc
• Integration Testing. sdlc
• System Testing.
• Acceptance Testing.sdlc

Applications using V-Model sdlc

• Used for small to medium-sized projects where the requirements defined clearly and fixed. sdlc
• When enough technical resources are on hand with the required technical skills. sdlc

Why you should use V-Model sdlc

• The progress of the project goes systematically. sdlc
• Suitable for small and medium-size projects.sdlc
• Testing will start from the requirement phase. sdlc
• Tracking the progress of the project is easy.
