Independent Software Verification and Validation (ISVV) is targeted at safety-critical software systems and aims to increase the quality of software products, thereby reducing risks and costs throughout the operational life of the software. The goal of ISVV is to provide assurance that software performs to the specified level of confidence and ...
Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
Software verification is a discipline of software engineering, programming languages, and theory of computation whose goal is to assure that software satisfies the expected requirements. Broad scope and classification
Formal verification of software programs involves proving that a program satisfies a formal specification of its behavior. Subareas of formal verification include deductive verification (see above), abstract interpretation, automated theorem proving, type systems, and lightweight formal methods.
These specified procedures and outlined requirements lead to the idea of Verification and Validation and software testing. It is distinct from software quality assurance which encompasses processes and standards for ongoing maintenance of high quality of products, e.g. software deliverables, documentation and processes - avoiding defects.
The verification and validation of a simulation model starts after functional specifications have been documented and initial model development has been completed. [4] Verification and validation is an iterative process that takes place throughout the development of a model. [1] [4]
Today, Independent Verification and Validation (IV&V) is an Agency-level function, delegated from OSMA to Goddard Space Flight Center (GSFC) and managed by NASA IV&V. NASA's IV&V Program's primary business, software IV&V, is sponsored by OSMA as a software assurance technology. Having been reassigned as GSFC, NASA IV&V is Code 180 (Center ...
"Validation. The assurance that a product, service, or system meets the needs of the customer and other identified stakeholders. It often involves acceptance and suitability with external customers. Contrast with verification." "Verification. The evaluation of whether or not a product, service, or system complies with a regulation, requirement ...
