In Systems Engineering, What is Verification? What is Validation? What are their similarities and what are the differences?
Verification : It is a process for determining whether a product fulfills the requirements and specifications established for it or not.
Validation : It is the assessment of a planned and delivered system to meet and satisfy the client's operational need in the realistic environment achievable.
In other words, validation is concerned with checking that the system will meet the customer’s actual needs, while verification is concerned with whether the system is error-free or not . Verification will help to determine whether the software is of high quality, but it will not ensure that the system is useful or not.
