Verifying and validating software requirements and design specifications

Boehm In other words, software verification is ensuring that the product has been built according to the requirements and design specifications, while software validation ensures that the product actually meets the user's needs, and that the specifications were correct in the first place.Software verification ensures that "you built it right".Verification can be in development, scale-up, or production. Validation is intended to ensure a product, service, or system (or portion thereof, or set thereof) results in a product, service, or system (or portion thereof, or set thereof) that meets the operational needs of the user.For a new development flow or verification flow, validation procedures may involve modeling either flow and using simulations to predict faults or gaps that might lead to invalid or incomplete verification or development of a product, service, or system (or portion thereof, or set thereof)." "Building the right thing" refers back to the user's needs, while "building it right" checks that the specifications are correctly implemented by the system.In some contexts, it is required to have written requirements for both as well as formal procedures or protocols for determining compliance.

It is normally the responsibility of software testers as part of the software development lifecycle.

A set of validation requirements (as defined by the user), specifications, and regulations may then be used as a basis for qualifying a development flow or verification flow for a product, service, or system (or portion thereof, or set thereof).
