Verification refers to the process of evaluating and checking the product during the development process to determine whether it meets the specified requirements. Verification techniques include reviewing requirements, designing and reviewing plans, conducting inspections and walkthroughs, and testing the product against requirements.
Validation refers to the process of evaluating the software at the end of the software development process to determine whether it is fit for its intended use and meets the specified requirements. Validation techniques include functional testing, performance testing, security testing, and acceptance testing.
In conclusion, verification focuses on checking the product during the development process, while validation focuses on evaluating the product at the end of the development process to ensure that it meets the specified requirements and is fit for its intended use. The specific techniques used for verification and validation may vary depending on the type of product being developed and the specific requirements and constraints of the project.
