Validation during the software development process can be seen as a form of User Requirements Specification validation; and, that at the end of the development process is equivalent to Internal and/or External Software validation. Verification, from CMMI's point of view, is evidently of the artifact kind.
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
"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 ...
Validation is the complementary aspect. Often one refers to the overall checking process as V & V. Validation: "Are we trying to make the right thing?", i.e., is the product specified to the user's actual needs? Verification: "Have we made what we were trying to make?", i.e., does the product conform to the specifications?

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]
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 ...
