V Model Advantages and Disadvantages: SDLC is the acronym used for the software development lifecycle. It is a framework development that organizations apply to the systematic and cost-effective production of high-quality software.
Both large-scale and small-scale software organizations utilize the SDLC method to build reliable and effective software. These organizations follow development standards that range from quick to lean methods to a waterfall and similar others.
The software development lifecycle supplies all organizations with a systematic, step-by-step strategy to generate successful software from assembling the primary requirements for a fresh and original product.

The SDLC consists of various models, one of which is the mention-worthy V Model.
The V Model is a kind of SDLC model where the process performs sequentially in a V shape. It is also known as the Verification and Validation model or V Model. It is based on the association of a trial phase for each analogous development stage.
In simpler words, the V Model is developed during the development of each movement which is directly associated with the trial phase. The following phase starts simply after the completion of the last phase for every development activity; there is a specific testing activity corresponding to the phase prior.
What is Meant by V Model?
One of the notable benefits of the waterfall STLC model was the defects found later by engineers at the end of the software development cycle.
It grew highly challenging and expensive to fix the defects since engineers found them at a very later stage. Hence, a new development model was introduced to overcome this problem. This development model was termed the “V Model.”
V model presently is one of the most extensively used software development processes. The foundation of the V model has confirmed the implementation of testing right from the fundamental phase of the development of software. V model is also known as a verification and validation model.
To follow the V model, users should first understand what the role of verification and validation is in software development.
Verification
Verification is an inactive analysis method. In this method, testing is carried out without administering the code- for instance, inspection, reviews, and walk-through.
Validation
Validation is a dynamic analysis method where testing is carried out by administering the code- for instance, including subjects like functional and non-functional testing systems can be categorized under validation.
The V Model consists of various phases for different stages.

Advantages of V Model
- Uncomplicated Use: The framework of the V model is highly uncomplicated. The environment is quite user-friendly and provides a solid base for or software development for small-scale developers. The design environment is relatively straightforward and finds candid used in the software development industry.
- Time saver: V model is simple to use, and trial activities such as designing, planning, and development take place before coding the software, which saves a turn-off time for busy developers who are heaped with work about the day. The chance of success due to quick designing and a well-integrated system is also the cost for higher success rates.
- Proactive error-tracking: The V Model environment consists of a proactive error tracking method that helps engineers fix bugs and other system errors and build the software in less time than the available time frame.
- No downward data flow: The V Model design framework is highly sophisticated and hence has no loopholes. It does not allow unidirectional or downward data flow during the development process of the said software.
- Straightforward design: The design of the V Model is quite simple. The developers of the V model work to make this model straightforward to understand; hence they have made the architecture simple yet highly efficient.
Disadvantages of V Model
- Highly rigid: The V Model is highly rigid. It is formed for the ease of development of highly complicated software. The V Model is relatively rigid in the case of utilization. The structure may seem simple, but the execution and methods are pretty complex compared to other design environments or models.
- Limited flexibility: The V model is not very flexible. It isn’t elementary and takes time for new developers to get used to it. The architecture is easy to follow, but it has limited flexibility in terms of design. It is overall not suitable for use in the process of development of object-oriented projects. The model design does not support highly complex calculations either hence it is very inadequate for use.
- No prototype guidance: The V Model software is developed during the implementation phase, so no initial prototypes of the software are produced. Due to the lack of prototype guidance, it is unsuitable for use to develop complicated or professional software that requires a precise, solid, and sound execution design.
- Mass updating: The process of software development is fraught with trouble and errors. Engineers try their utmost to develop a model to build the best software that suits every requirement. To make sure the developed model is at its finest, there are many trial and error stages involved. The worst drawback about the V Model is its update feature. Unlike most highly professional software, the V Model uses massive updates of both the test documents and requirement documents if something goes wrong midway.
- Risky: The management of the total environment is volatile and risky. It is not suitable for use to build object-oriented software due to its uncertainties in the design.

FAQ’s on Pros and Cons of V Model
Question 1.
What are the requirements for the software development of the V Model?
Answer:
The requirements for the software in the analysis phase are accumulated by analyzing the requirements of the. This particular phase has to do with what the development system has to perform. Generally, the users who will be using the software are interviewed, and an official document is generated accordingly.
Question 2.
What is the architecture design of the V Model Software developer?
Answer:
The design of the computer architecture can be referred to you as a professional design. The foundation is selecting the architecture that can realize all the major components of various models and their functionality. It also includes details about architecture diagrams, interface relationships, database tables, etc.
Question 3.
What is the primary disadvantage of the V Model?
Answer:
The major disadvantage of the V Model is its rigidity and most limited flexibility. If any changes occur midway, then developers must update the test documents and also requirement documents.
