Validation & Verification

In this section, we will study about verification & validation. Therefore, to make yourself familiar with the terms, follow the content below.

Verification

Firstly, validation refers to the process of evaluating a software product during a particular development phase. In other words, it determines if the product meets the requirements set out at the beginning of the phase.
Secondly, the phase is static and includes verification of all the necessary documents, code, design and program.
Thirdly, it includes all the activities that ensure the delivery of the best quality products. For instance, design analysis, inspection,etc.
Fourthly, some of the common methods to conduct verification incorporates meetings, inspection, and review.

Validation

Firstly, validation refers to the process of testing a software product after its development process gets completed
Moreover, it is set out to identify whether a particular product meets the pre-determined requirements or not.
After that, it is a dynamic process. That is to say, it evaluates a product on parameters that help evaluate whether it meets the expectations and requirements of the consumers.
Lastly, some common methods of conducting validation include black-box testing, white-box testing, and grey box testing

Verification	Validation
Firstly, to Check documents, codes, and programs	Firstly, to validate the Product
Secondly, no code execution	Secondly, code execution
Thirdly, the static method	Thirdly, dynamic Process
Fourthly, prepense for database design, architecture, specification, high level, etc	Actual Product is the target
Fifthly, uses reviews, inspections, and desk changing for verification	Uses non-functional testing, black box testing, white box testing, etc.
Sixthly, QA Team is responsible	Development as well QA is responsible
Lastly, checks manually checking requirement specification	Lastly, used for checking developed program based on the requirement specification
