Verification & Validation (V & V)
Verification is the process of checking that software achieves its goal without any bugs. It is the process to ensure whether the product that is developed is right or not. It verifies whether the developed product fulfills the requirements that we have. Verification is simply known as Static Testing. Validation is the process of checking whether the software product is up to the mark or in other words product has high-level requirements. It is the process of checking the validation of the product i.e. it checks what we are developing is the right product. it is a validation of actual and expected products. Validation is simply known as Dynamic Testing.
Key Components:
- Verification and validation are both crucial aspects of the software development and quality assurance process, but their importance can vary depending on the stage of the development life cycle.
- Verification primarily focuses on ensuring that a product is built correctly according to its specifications. It involves activities such as code reviews, inspections, and testing to identify and fix defects in the early stages of development.
- On the other hand, validation is concerned with assessing whether the software meets the customer’s needs and expectations. It involves activities like system testing, acceptance testing, and user feedback.
- While both verification and validation are essential, their significance may depend on the context. Early in the development process, verification is crucial for identifying and rectifying issues promptly.
- As the development progresses, validation gains importance to ensure the software aligns with user expectations and requirements. Ultimately, a balance of both verification and validation is necessary for delivering a high-quality and reliable software product.
- In summary, the complexity of understanding and addressing user needs, the subjectivity of requirements, and the challenges associated with real-world testing make validation a more intricate and demanding process compared to the more straightforward nature of verification.
