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.
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 and validation, in engineering or quality management systems, is the act of reviewing, inspecting or testing, in order to establish and document that a product, service or system meets regulatory or technical standards
These examples show several common methods that Wikipedia editors use to make their articles verifiable. Wikipedia editors are free to use any of these methods, or to develop newer methods—no particular method is preferred. However some method is required and each article must use the same method throughout the entire article. (When making ...
Verification: "Have we made what we were trying to make?", i.e., does the product conform to the specifications? The verification process consists of static/structural and dynamic/behavioral aspects. E.g., for a software product one can inspect the source code (static) and run against specific test cases (dynamic).
Static verification, also known as analysis or, static testing - This is useful for proving the correctness of a program. Although it may result in false positives when there are one or more conflicts between the process a software really does and what the static verification assumes it does.
Verification is an auditing process in which auditor satisfy himself with the actual existence of assets and liabilities appearing in the Statement of Financial position. [1] Verification is usually conducted through examination of existence, ownership, title, possession, proper valuation and presence of any charge of lien over assets .
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.
