V-model advantages and disadvantages

V-model advantages and disadvantages

Introduction to V-model advantages and disadvantages

The V-model is one of the Software Development Life Cycle(SDLC) models; it mainly seems to be the execution of the processes that can be happened with the sequential steps that must be the V- shape so that the datas are considered as the Verification and Validation model the V represents the Verification phases on any side of the Validation area of the other sides it should follow the certain steps and stages for to complete the cycle here the stage represents phases the main advantage of the V-model is to save the time, proactive defect tracking when compare to the waterfall model. In this topic, we are going to see V-model advantages and disadvantages in detail.

Advantages and Disadvantages of V-Model

We already know about the V- model type and its usages. However, it is mainly considered to save a lot of time compared to the other SDLC cycle models, especially the waterfall model. This is because the V represents the Verification and Validation; it is used to validate and check that the software system meets the specifications and other requirements so that it fulfills the user’s needs and its intended purposes. Therefore, it has higher chances of success over the waterfall, which is used for the model, and also it is the proactive measure and defect tracking that will defect which found at the early stage of the testing activities.

Again V-model is the pictorial and graphical representation of the systems, and it’s the development cycle which used to produce the rigorous development lifecycle models and the other project management tools and models. So that it denotes and is referred to as the general testing model, and mainly it represents the US government standard. Generally, the V- model is used to regulate the software development process within the standard and federations like German federation administration because the German federation administration and its defense projects are denoted and called with each region. Compared to other SDLC models, V-model is easier to manage and use in projects like small-scale industries. It is highly disciplined with the model, and the phases are completed for the execution once at a time. Due to the V-model usable for the small projects whereas the requirement of the projects is more clear at the time of the initial phase lifecycle.

We all know about the phases of the SDLC because, after analysis of the requirement, the system design phase is the main part of the application. Because due to the system design, the entire description of the system components like hardware and other software communication setups for the product development. So that the device plan is mainly set up and it is based on the system design due to this stage phase, it will leave the time for spending more time for the actual test execution based on the test scenarios. After this phase, the Architectural design phase is used for system design and to implement the application in the technical phase and also, in this phase, the application modules will be broken into separate modules with taking different functionality so that it denotes the High-level design phases simply called it as HLD. After this phase, the next level is the module design, and it is named the internal design and specified for the system modules, also referred to as the low-level design pattern. This design phase will be compatible with the other modules and other external systems with a different architecture.

It is easy to manage due to the rigidity of the models for each phase of the project deliverables, and the review process is also handled for user convenience. But it has some disadvantages like high-risk capability for uncertainty nature so that it’s not a good model for high and big complex object-oriented projects they have the difficulty for to handle the project datas because of this model. And also, when compared to other models, it’s not a good model for long and current ongoing projects that is not suitable for the projects where the requirements are at the high-moderate rate for the high risk of changing the datas. On the positive side, the primary engineering activities have flowed with the logical flow that can be easily covered and understandable with the balance development activities for corresponding activities. So that the V-model does not adequate with the capture development from the testing point of view. This model focuses on the verification and validation activities early in the lifecycle, thereby enhancing the probability of building the errors and free with good quality products. They may be enabled the project management to track the task progress in some accurate manner. On the disadvantage side, it has high risk and also does not easily handle concurrent events. No working software and application is produced with usages and until some late duration for the life cycle. The module design is the low-level design that can be called and denoted as the LLD. It is important that the design is more compatible with the other design modules in the system architecture and external systems. In V-model, even though the other models, the unit test is the most important one for the development process. It helps to eliminate the maximum faults and errors at the early stage levels. So that the unit test will be assigned for this stage, and it depends on the internal module designs.

The V-model have some types like single V-model, double V-model and triple V-model these type of models are used with the traditional testing from the testers point of view. Major verification technique to intended with the product behavior with known inputs from the user.

Conclusion

Generally, the SDLC models are used to understand the workflow of the projects whenever we start the project from our end. Based on the scenarios, many models are available and followed by the technical people; among that V-model is the model for budget and other small-scale projects.
