Validation - Validation is a process. It uses objective evidence to confirm that the requirements which define an intended use or application have been met. Whenever all requirements have been met, a validated status is achieved. The process of validation can be carried out under realistic use conditions or within a simulated use environment.

In the context of this standard, the term validation is used in at least two different situations: design and development and production and service provision. Design and development validations use objective evidence to confirm that products meet the requirements which define their intended use or application.

Production and service provision processes must be validated whenever process outputs cannot be measured, monitored, or verified until after the product is in use or the service has been delivered (by then it's too late to do anything about output deficiencies and defects). In this case, validations use objective evidence to confirm that production and service provision processes are capable of producing planned results.

validation -

(1) [software] The process, using formal methods, of evaluating a system or software component to determine whether it functions as expected and achieves the intended results.

(2) [Category=Data Quality ] The process, using formal methods, of evaluating the integrity and correctness of data or a measurement.

(3) [modeling] In modeling, the evaluation of a method to show whether it is assessing the parameter of interest rather than something else.

(4) [Category=Data Quality ] The process of comparing the topology rules against the features in a dataset. Features that violate the rules are marked as error features. Topology validation is typically performed after the initial topology rules have been defined, after the feature classes have been modified, or if additional feature classes or rules have been added to the map topology.
