And validation would be tasting the cake before serving it to guests and finding out if it’s way too salty. We may liken verification and validation to the following analogy about baking a cake where verification would happen when checking the ingredients and method. In short, both verification and validation are quality control processes.Įxamples of Verification and Validation (How to Do Each) And validation can further validate that the final product functions correctly. For example, performing verification prevents errors in the requirement from making it to the implementation (coding) phase. Both check that the product meets specific requirements and standards. The main objective of verification and validation is to improve the overall quality of a software product. How Verification and Validation Are Related Verification processes include reviews, walkthroughs, and inspection, while validation uses software testing methods, like white box testing, black-box testing, and non-functional testing.Verification comes before validation, hence it finds bugs early while validation finds bugs that verification can’t detect.Validation, on the other hand, requires a product or code to execute. It is possible to perform verification without the finished product.With verification, quality assurance (QA) personnel are responsible for the processes, whereas, with validation, software testers run the tests.The following points show the differences between verification and validation: What is the difference between Verification and Validation? detects errors that verification can’t. ![]()
